Coordinate Systems Service (CSS)
• An issue where the WKT alias containing the Mercator 2SP Variant B map projection operation was not
recognized automatically by our software, has been fixed.
• The identification of Krovak Modified (Greenwich) and Krovak North Modified (Greenwich) map
projection operations has been improved. In some rare cases, WKT aliases containing these map
projection operations could be misidentified as Krovak map projection operations.
12
Aspen Epos V14.2 Release Notes
Epos Data Management
Data Import/Export
New Features and Enhancements
CLI Utilities
• A new CLI utility (UpdateUSIandClass) that enables bulk update of the Unique seismic ID (USI) and the
Class of seismic files, has been implemented. The utility should be run from Epos terminal and will
update these parameters using an external text file that defines the old and new values.
Epos Seismic OSDU Connectivity
The connectivity of our Epos Applications to OSDU seismic repositories has been updated:
• A new user interface for Application Administrators to define and store the parameters of an OSDU
connection with Epos has been introduced, with secure storage of those parameters.
• We have refined the metadata transferred between Epos and OSDU with seismic read and write
operations, to better facilitate inter-vendor interoperability through OpenVDS storage in OSDU.
• We now supply a simple utility to explore the metadata associated with OpenVDS volumes in JSON
format. This is available from MB3 in the Register from OSDU dialog.
By default, these options are hidden from Epos Application users in V14.2, but can be enabled simply by
Application Administrators. Please reach out to an AspenTech SSE contact should you wish to learn more,
and we will be happy to support you in your OSDU journey.
Seismic Data Manager
• An option to move files between paths has been added in the seismic data manager. This enables you to
quickly move seismic data between file systems, such as for NAS and web-native storage on the cloud.
In addition, application administrators can define Path Labels when defining managed data paths.
These will be seen in the move files dialog box, enabling an easier and clearer understanding of the
target path.
Aspen Epos V14.2 Release Notes
13
Session Manager
• The tolerance parameter for Low/Med/High Prestack Compression can now be set in the Session
Manager> Customize> General> Seismic Compression Tolerance.
The tolerance parameter controls the level of compression, it can be set between 0.0001 and 0.999. A
value closer to 1 results in higher compression and larger loss. A smaller value reduces the compression
rate and improves the quality.
Files generated in the different applications (Echos, SEG-Y Import, Migrations, SO) will use these
parameters according to the selected output file format.
The tolerance factor used is written in the File Attributes> User Defined.
• Images can be taken using the 'Take Snapshots of Opened Windows' option from Session Manager
Home tab. The option is available only when P&I Utilities are installed and configured.
The images are saved to the relevant Epos Survey database.
The images can be managed by the Image Manager utility and used in the Reporting utility to create
presentations. See P&I Utilities.
Well Manager
• The "not equal" condition (!=) has been added to the Select Wells by Criteria dialog box.
Software Fixes
ASCII Import
• Offset reference and Z-values columns are now handled correctly in the default VFNDEF format when
importing On/Off Mute functions.
• Well header constants of existing wells can now be updated when importing Well Parameters.
Project/Survey Manager
• The issue prevented setting of the Depth direction using the "Positive/Negative below sea level" option
has been resolved.
SEG-Y Import/Export
• Shape files exported from an Epos database can now be used to correctly position vertical images
loaded through the SEG-Y Loader.
14
Aspen Epos V14.2 Release Notes
Session Manager
• The Prestack AutoPicker application can now be added to the Favorites tab of the Epos Applications
Session Manager.
Vertical Function Manager
• The maturity labels for vertical functions are now saved into the Vertical Functions Database. Vertical
Function maturities that were set in previous versions will not be read and should be reset manually.
Well Manager
• Shape files generated from the Well Data Manager now contain database (.dbf) information that is
compatible with ArcGIS.
• In the option "Create Position from Directional Survey" the default masking of input log names could
cause problems with the operation. Fixes have been made to the software to prevent these issues from
occurring.
• An issue that could result in severe performance challenges in the Well Data Manager, in Projects
containing more than one Well Database and large numbers of wells, has been addressed. Specifically, if
no well lists had been selected in Well Data Load settings for certain Well Databases, the Well Data
Manager Well Lists subtab would scan all the wells in those Well Databases. This no longer occurs by
default. Now, the scanning only occurs when you select those well lists in Well Data Load Settings or
enable the 'Show All Lists' option in the Well Lists tab.
• In some cases, the well header constant SPUD_DATE (and other textual dates) might be ambiguous, due
to differing geographic norms for defining dates as DD:MM:YY or MM:DD:YY. Internal application logic to
determine which protocol is in use can break down in case where both DD and MM are less than 12.
To address this issue, the 'locale' of the user's workstation is now used to determine which format to
assume.
In case the predicted format from the current locale would differ from what was used by the data
loaders for a database, the environment variable
PG_WELL_SPUD_DATE_REVERSE can be used to 'reverse' the logic. For example, if DD:MM is predicted
by the locale, then MM:DD will be used, and vice-versa.

Interpretation
Aspen SeisEarth (including Explorer & QSI)
New Features and Enhancements
Crossplot
• A new paint scheme, rock-physics coloring, was added to the crossplot. When using this paint scheme, it
is possible to generate rock-properties volume from amplitude inversion results and a rock-physics
model in a few mouse clicks.
Options relating to if/how to color the crossplot points located outside of the rock-physics model grid
are available from the Rock-Physics Model Marking Parameters option accessible by right-clicking on the
crossplot panel.
Note We recommend that you start generating a crossplot of the invertion result from a 3DCanva,
focusing on your layer of interest, such as P-impedance versus Vp/Vs. Then, a rock-physics model
previously calibrated on the well data should be displayed on the crossplot. The datatype used to
color the rock-physic model must correspond to the datatype of the rock-property you want to
generate. By enabling the Paint Crossplot option and Marking Data by Background Color, you can
automatically create the volume of the desired property in 3DCanvas within the limit of the data
cross-plotted. This volume can be saved by right-clicking on the generated crossplot volume in
3DCanvas Display Element tab.
• When using Relation for painting, the Relation can now be automatically extrapolated to the display
extents. By default, the extrapolation option is off, but you can control its default state in Customize >
Global Preferences > Paint > Relation. You can also enable or disable this option from MB3 > Relationship
Parameters.
• In Customize > Plot Axes & Grid Definition there is a new option, User-Defined (Fixed No. of Bins), which
provides the ability to define the number of bins of each crossplot axis.
• It is now possible to color multiple crossplot elements by Z axis. This new option is available whether the
Z axis is a property or a histogram. It is limited to cases where the crossplot elements to color have
consistent datatype, color scale and value range.
• When coloring a log crossplot by a third attribute, you now have the option to display points (in the color
of your choice) when Z axis values are undefined. In previous versions, these points were automatically
16
Aspen Epos V14.2 Release Notes
removed from the crossplot. This option is available from Crossplot Global Preferences > General.
• Selection of rock-physics model cells has been enhanced. Using the Edit tool
:
A new Select All Cells option is available when right-clicking on a rock physics model.
Drawing a line between two cells of a rock physics model will select all the cells intercepted by the
line.
Global Velocity Model
• The Model Extend Tab has been renamed to Model Geometry. Addiotional enhancements available in
this tab include:
In the "user defined rectangle" option it is now possible to align output grid geometry to 3D survey
inline/crossline grid.
A new option to laterally limit the Global Velocity Model by existing AOI/Polygon, "Area of Interest
Bounding Box". Any Area of Interest from the project or surveys in the project can be selected.
When Scaling and Preview, the "Use Exact AOI Polygon” option can be used to constrain results to
the AOI.
Integrated Canvas
General
• The management of Maturity Labeling in Epos has been extended to the Integrated Canvas.
Interpretation objects can now have their maturity set by users within the BaseMap, Section and 3D
Canvas plugins. The Set Maturity option is added to interpretation objects context menu.
"Gold status" data now gets special treatment: this maturity level can only be set/unset by users with
Administrator privileges, and objects that are labeled as gold cannot be edited or deleted from within
the plug-ins. Changes to cursors and pop-up warnings are issued if users attempt to do so.
• A new implementation of the 3D Horizon Propagator as a Workflow for Interpreters is available in this
release. It provides a workflow-driven user experience, with enhancements over the previous user
interface including an audit trail of steps to create horizons, built-in lasso-constrained, editing,
replayability and the ability to copy and rerun the exact same steps for propagation with different input
Aspen Epos V14.2 Release Notes
17
volumes (for example, for AVO or 4D comparisons). The Workflow can be used with the 3D Canvas,
Section and BaseMap plugins of the Integrated Canvas.
The previous user interface for 3D Propagation in the 3D Canvas is being maintained alongside the new
implementation in this release, due to some of its unique features (prestack propagation and
constraining by T-surfs). You should be aware that there is no 'communication' between the two
implementations, meaning that they should not be used in parallel to pick the same event. We are eager
to receive feedback from you regarding the new implementation.
3D Canvas
• Saving and opening of Displays is now supported in 3D Canvas. Users can save Displays at any time from
within 3D Canvas, and open the saved Displays later to quickly restore the scene as it was when saved.
Unlike the use of Sessions, opening a Display does not involve closing and restarting the Integrated
Canvas. In addition, only data that is not already loaded will be opened into the application, which
makes the Display restoration much faster. You can Save, Open and Delete Displays from File> Displays.
• For Grids & 3D Horizon Picks, an option to save with an applied shift has been added. The Save As dialog
box has a new toggle, Save with Shift which is enabled when shift is applied to the data.
BaseMap
• Creation of Q-factor related maps is now available in Mathematical Operations.
Section
• Options to reorder layers inside Section panel have been added. This can be done in the following ways:
On the Section display, use context menu option Move Top Layer To Bottom to move top layer to
the bottom.
Using Shift+B shortcut, this will move top layer to the bottom.
In Section Display Elements, context menu on the layer element using one of the options: Move
Layer to Top, Move Layer Up, Move Layer Down, Move Layer to Bottom.
• An option to export seismic data to SEG-Y file from a displayed traverse, has been added. This enables
the export of seismic data from different line geometries as a single SEGY file.
The Export to SEG-Y option is available from Section context menu when a traverse is displayed in the
panel. The displayed traces will be exported.
• Shortcut key "E" can be used to synchronize displays in panels in Synchronize Geometry Mode.
Well Log Window
• Flattening in Well Log Window - a new option has been added to flatten the display on a selected grid or
marker, when displaying multiple wells. When using markers, the markers should be assigned to the
same feature.
• To generate intervals for multiple wells simultaneously, it is no longer necessary to display all the
desired wells. Loading these wells in Well Log Window is now sufficient.
18
Aspen Epos V14.2 Release Notes
• It is now possible to close multiple panels in one click. Several options are available from the panel title
bar:
Poststack Inversions (including Maximum Likelihood Inversion (MLI))
• When the vertical output range is horizon-oriented, inversion is only performed on traces for which the
horizon is defined. Where the horizon is not defined, the traces are skipped.
Seismic Operations
• Seismic Operations > AVO Inversion > AVAZ attributes
The minimum number of input volumes needed to calculate AVAZ attributes (number_of_azimuths +
number_of_angle_stacks) has been reduced to 9, enabling calculation of attributes when 6 azimuth
sectors and 3 angles stacks are available.
Synthetic-Seismic Utility
• In the wavelet panel of the Wavelet and Calibration tab, an option to display a wavelet previously saved
in ASCII has been added. This wavelet will be displayed in the background and will not be used for
synthetic estimation. It is loaded using Reference Wavelet > Load Reference Wavelet available by rightclicking on any display panel. The reference wavelet can be hidden from the display by toggling it off
using the Reference Wavelet toggle located underneath the wavelet display panel.
Vertical Functions
• Crossplot relationship for Q-factor related vertical functions can now be saved. Note that this
relationship can be opened only in the Vertical Functions Window when opening Crossplot for displayed
Q-factor related functions.
• It is now possible to extract vertical functions at the intersection points with grids or markers.
• Extract from Volume/Section no longer allows users to input inline/crossline values that do not exist in
the survey (for example, due to step values greater than one).
• If a user changes the color of a surface in the Interpretation Manager, the corresponding color of the pick
intersection in the Vertical Functions Window will update immediately.
Workflows for Interpreters
3D Geostatistical Operations
The following additional features have been added to the 3D Geostatistical operations. These are being
released as a beta version and are available only when using FlexNet license under the MSI add-on to
the QSI-RFP license.
Aspen Epos V14.2 Release Notes
19
Relative Geological Time (RGT) volumes describe the stratigraphic layering of an area. The RGT
option enables the creation of these volumes using horizons/grids and internal layering; or using
Geological or Stratigraphic grids created in Aspen SKUA. The RGT volume is a compulsory input of the
Fast Stochastic Inversion workflow.
The Background Trend option combines the generation of log property volume using (co)kriging
followed by high-cut filtering. This option can be used to generate background models for inversion,
background trend for Fast Stochastic Inversion, velocity volume from velocity logs. The stratigraphy
used in the kriging process is performed within a stratigraphy described by horizons/grids and
internal layering; or using Geological/Stratigraphic grid created in Aspen SKUA. This option benefits
from a preview of the kriging output and the output of the high-cut filtering on a restricted geometry
to help the user choose optimum parameters.
Attribute Clustering Workflow
Two new parameters have been introduced in the Create Training Set dialog box:
Vertical Half Window Size (samples) - This new parameter provides an option to apply a sliding
window when creating the training set, so samples above and below the current sample are used to
build the training set. Using this parameter in multiple datasets has proven to improve the quality of
the model. For most datasets, the ideal value for the sliding window is between 3 and 5.
PCA – this applies Principle Component Analysis to the training set data. It is recommended to use
when using the Vertical Half Window Size in order to reduce the dimensionality of the training set and
improve performance.
Neural Network Inversion (NNI)
A New implementation of Neural Network Seismic Inversion as a Workflow for Interpreters is available
in this release.
Neural Network Inversion uses convolutional neural network to predict log properties away from well
control.
The method uses neural networks trained on the input data (seismic/seismic attribute data and input
well logs) to predict properties (attribute volumes, maps or logs).
This new delivery includes several improvements and new functionality, including:
20
Aspen Epos V14.2 Release Notes
An Attribute Contribution Analysis option to rank the input seismic volumes relative to their
contribution to the quality of the training for the selection of an optimal set of input attributes.
Training auto-stopping conditions and training convergence QC.
Training quality QCs.
This implementation leverages the benefits of A Workflow for Interpreters wizard-driven interface,
including:
• Intuitive user guided interface
• Access to parameter testing and permutation
• Option to chain with other Workflows for Interpreters
• Workflow report
The workflow is available from Integrated Canvas > Analysis/QSI > Inversion.
Fast Stochastic Inversion (Beta)
This is a beta version of Fast Stochastic Inversion (FSI) workflow.
Fast Stochastic Inversion is based on the same concept as the Modified Stochastic Inversion (MSI): The
deterministic inversion result is merged, in the frequency domain, with gaussian simulation to generate
multiple high-resolution realizations of impedances whose synthetic are tying the seismic. In the Fast
Stochastic Inversion, the Sequential Gaussian Simulation method has been replaced by the Turning
band simulation method, improving processing parallelization and speeding it by a factor of 2 to 2.7.
Additional outputs such as Vp/Vs, Poisson ratio, LambdaRho, are also available in elastic mode as well
as some realizations of lithofacies and statistics.
In FSI, the workflow usability has been enhanced. QCs of well logs smoothing, preview of simulation for
the low and high frequency components, and spectral merging results are available to help the user

Licensing Token Model Update
We have adjusted the core funcionality of token-based licensing for Aspen SeisEart. This enhancement
provides you with more flexibility in how you use the tokens in an interpretation workflow.
In this V14.2 release, we have effectively split the functionalities that were previously grouped together
in the (now deprecated) SeisEarth Daily token feature into two groups:
SeisEarth Interpretation enables the interactive creation, manipulation and editing of interpretation
objects, and certain other core interpretation functionalities, including:
Gridding and contouring
Volume rendering
Flattening
Seismic mistie analysis and correction
Aspen Epos V14.2 Release Notes
21
SeisEarth Advanced Interpretation enables wizard-driven, more advanced interpretation features and
workflows, including:
FaultTrak
Horizon Propagator
Subvolume Detection and Geobody Sculpting Workflow
Interval Attributes Workflow
Extract Seismic Attributes
4D QC
The significant change in V14.2, compared with previous aspenONE releases, is that the tokens
associated with the SeisEarth Advanced Interpretation feature can be checked back into the token pool
without having to close the Integrated Canvas. If you are not using any of the features associated with
SeisEarth Advanced Interpretation and you close the user interfaces that control them, those tokens
will be released back into the pool. They will then be available for use with other SeisEarth features, by
other users or in other applications from the AspenTech Subsurface Science and Engineering portfolio.
Please note that the sum total of tokens associated with SeisEarth Advanced Interpretation and
SeisEarth Interpretation is the same as it was for SeisEarth Daily. If one or more features from both
SeisEarth Interpretation and SeisEarth Advanced Interpretation are in use at the same time, then the
number of tokens checked out from the pool will be the same as it would have been with SeisEarth
Daily.
In order to use the functionalities enabled by these two new features, your application administrators
must be sure to have configured your V14.2 installation with an updated license file that contains them.

Aspen Epos V14.2 Release Notes
31
• If the borehole image orientation reference is changed (for example, from North to TOH) when picking
dips, all existing apparent azimuth (AZIM_APP) values in the dip set will now be automatically
recalculated to correspond with the new orientation reference.
• The Image 3D track performance has been improved.
• A new tool, Rotate Image, has been added to enable you to interactively orient an image in an image
track. This tool provides the ability to orientate a circumferential core scan using a borehole image as
reference.
• A warning message is now displayed when box style (for example, breakouts) and line style features (for
example, tensile fractures) are displayed in a Dip track in a highly deviated well (deviation > 80 degrees)
using the default AZIMUTH (true azimuth relative to North) log. In highly deviated wells a reliable true
azimuth for breakouts and tensile fractures cannot be determined. Therefore, the apparent azimuth log
(AZIM_APP) displaying the azimuth relative to TOH should be used as the azimuth log in the Dip track.
Licensing
• When Aspen Geolog needs to exit because of a license failure, you are now given the opportunity to save
your work.
• A crash dialog box is no longer displayed if the license server connection is lost.

Badhole logic is applied or the DEXP or SIGMALOG is calculated.
• The DEPTH_WATER input constant has been removed and the SURFACE_ELEV constant is now used for
the Depth below mudline computation both in Onshore and Offshore wells. The WELL_ENV input
constant is used to check that the input SURFACE_ELEV value is correct (positive for onshore, negative
for offshore).
Production Logging
• Tracks for matching the lateral averages of the apparent fluid velocity and the fluid identifier logs to
their zonal logs have been added.
• Calculated surface flow rates can now be matched with measured surface flow rates.
Aspen Epos V14.2 Release Notes
33
• An array tool spec must now only have at least one spinner, gas holdup or water holdup log. Previously,
an array tool spec was required to have all the tabs (spinner, gas holdup, and water holdup) populated
with one or more logs. This was an issue because a significant number of jobs are completed with a nonarray spinner (single spinner), an array of water holdup sensors and no gas holdup sensors, or some
combination of these. This change increases flexibility and caters to a wider range of production logging
toolstring combinations.
• The color associated with the selected Zone or Set is now displayed in the Display Selector panel, within
the zone or set selection list.
• The current Production Log view can now be saved to a .prodlog spec file. The following are saved to the
spec file: the Data Set value, the composite log plot zoom scale, array tool cross section colormaps,
array tool and image track appearance, Zone and Set list selections, and the selections in the Spinners,
Gas Holdups and Water Holdups tabs. The spec file can be opened to display a Production Log view
using the saved settings.
• The Display Calibration Zones in Plot panel now has a button to scroll the composite log plot to the
selected zone.
• Both water holdup logs and capacitance logs can now be used simultaneously as fluid identifier logs
when calculating water holdup in zones.
• If one of the selected phases is water in a two-phase flow, then an option is now available to use
capacitance and/or water holdup logs as the fluid identifier.
• Synchronized Positioning is now available for the composite log plot.
• The dialog boxes associated with selecting additional basic production logs for display in the composite
log plot have additional functionality:
Select Logs Log name and label are now displayed in selection list, button to delete log(s) from
selection list, and updated selection list is saved.
Add Logs Selecting a log in the selected set results in a new column with its cells automatically
populated with the log name.
• The downhole flow rate calculations have been improved with the following changes:
The PVT Correlations dialog box can now calculate downhole density and use the downhole density
for flow rate calculations.
Constants or logs can now be selected as the pressure and temperature inputs into the PVT
calculations.
Additional correlation methods are now available for the calculation of the Solution Gas Ratio and
Formation Volume Factor.
The inputs used to calculate Holdup and Surface Flowrate are displayed in the Calibration Zones
tables.
Query
• GeologSQL now supports array logs and expressions.

added. These compute oil, water and dissolved gas (in oil and in water) volumetrics. In addition, the
existing shale gas modules (shale_gas and shale_gas_cum) have been enhanced with an option to
compute dissolved gas in water volumes.
• In the TOC by the Delta LogR module (shale_toc_deltalogr), the LOM parameter can now be input as a
log.
• In the Water Saturation (shale_swt) module, SWT_ORG_SH now evaluates to 1 when VOL_KEROGEN is
equal to 0, even if the other logs used in the calculation are missing.

Aspen Epos V14.2 Release Notes
Modeling
Aspen SKUA
Overview
Aspen SKUA V14.2 delivers significant functionality and productivity improvements including the following
highlights:
• Improved performances when opening and saving large projects
• New Reservoir Properties Workflow Update and Replay
• Expanded Python API and improved scripting environment
• Enhanced data exchange with OSDU Data Platform through the introduction of a new OSDU/ETP
Connector dialog box
• Strengthened property model building and automation
• Interoperability with Building Information Modeling (BIM) applications through the addition of model
export capabilities in IFC format
New Features and Enhancements
Infrastructure
• Crash handler. When the application stops functioning, a crash report is now automatically created in
the temporary folder on your machine. When you contact customer support, you can attach this file to
the incident. The file does not contain any confidential information, only a function call stack that can
help our developers reproduce and resolve the issue more efficiently.
On Windows, browse to %TEMP% and search for a file named
SkuaSessionInfo-XXX.log, with XXX being the process ID number.
On Linux, the path to log file is indicated in the command prompt from which you started Aspen
SKUA.
Note: If you are running Aspen SKUA from the Aspen Epos Session Manager and the crash dump
setting of Epos is enabled, the Epos crash handler takes precedence.

Foundation
• Create surfaces from geologic grid units. You can now create surfaces from the geologic grid envelope
surface with the new command in Surface menu > New > Grid Section or Cage > Geologic Grid Unit. It
creates a closed surface per geologic unit. In the command, you can control the resample of the surface
mesh and copy the grid properties to the surfaces. This command could be used, for instance, to
reproduce the display of a geologic grid in volume and export it as surfaces to other applications such as
ArcGIS.
• Performances to open projects on remote disks. If you work with projects containing SKUA fault
networks and tetrahedral meshes (Solid 2.0), opening and saving the project has been optimized. On
average, we observed a time gain of 20% to open the project and 40% to save the project (if the data has
not been modified). Note that the performance gains are more visible when you work with projects
saved on remote disk and are heavily dependent on your network configuration.
• Internal coordinate system origin. You can now get information about the relative coordinate system
origin of your project in the Project Information dialog box. For numerical precision issues, Aspen SKUA
stores the object coordinates in a relative coordinate system. This information is exposed mostly for
users working with the JavaScript API and Developer Kit, who may have to manipulate the internal
coordinates of objects, or for advanced debugging purposes. Refer to Aspen SKUA > Getting Started >
Aspen SKUA Projects > Check Units in a Project for more information about the relative coordinate
system.
Maps, Cross Sections and Well Viewers
• New page template for maps. When you create a new page, you can use the new Maps template to
quicky create a page with a Map view and a Display Element. For FlexNet users only, the template
appears even if the Map Cross section and Well Viewer add-on is not loaded, in which case the page
simply opens without a map created.
• Editing curves in maps. You can now edit the curves or closed polygons in a Map view with the
Interpretation toolbar, even if use data projection distance is cleared in the map settings.
Note: We recommend that you use these editing tools for editing the geometry of curves that are in
the map datum plane only. For three dimensional objects, edit in a 3D Viewer.
Sequential 3D Restoration (Kine3D-3)
• Legend for state of constraints. In the Define Kinematic Constraint panel, when you enable the
validation of constraints (Show the state of constraints
) a color legend appears in the 3D Viewer for
enhanced usability.
• Computing stress vector from strain. In the Check Restoration panel, when you compute strain
tensors, you can now also compute the green Lagrange stress vector. Stress is computed from strain
with elastic parameters for each rock facies. In addition, the six raw tensor components
(sxx,syy,szz,sxy,..) can be saved as individual cell properties.
• Improved colormap management when checking results. In the Check Restoration and Tectonic
Analysis workflow panels, when you review the simulation results over geologic events, the
42
Aspen Epos V14.2 Release Notes
management of property colormaps has been improved so you can more easily compare the restoration
steps. The colormap range is no longer reset when you browse over time, and preserves the edits you
may have done to customize the display.
• Computing fracture orientation. Diffuse fracture proxies related to past strain or stress can now be
computed with the command in Kinematic Mesh command > Tools > Create Fracture Orientation
from Current Tensors.
The command computes either:
• Shear direction as a vectorial cell property
• Dip and azimuth as two scalar cell properties
You can choose the fracture type for computation: Joins, Shear fractures, Conjugated shear fractures
or Stylolites.
When using a Facies property as input, the rheological parameters, such as the Friction angle, are
retrieved from the associated rock classification.
• Creating cell center X Y Z properties on a Kinematic Model. You can now compute the X Y Z properties
at cell centers for the kinematic model using Kinematic Mesh commands > Property > Create or Reset
Cell Center XYZ for All Events. These properties are useful to create cell regions and filter displays by
these regions.
Reservoir Properties
• Updating (or replaying) a Reservoir Property workflow. You can now use the parameters defined in
an existing Reservoir Properties workflow to simulate the properties on a new grid.
After changing the grid in the General Parameter workflow panel, click the Update button to map all
parameters specified in the workflow to the new grid (regions, properties). You can then go to the
Simulation Control Panel and run the simulations.
Alternatively, from the Workflows tab, right-click an existing Reservoir Properties Workflow, and then
select Replay.
Watch this video to learn more about this functionality.
Updating or Replaying a Reservoir Property Workflow With a New Grid (2:23)
• Improved Cloud Transform algorithm. When using the Cloud Transform simulation method, a new
option Smooth transition between bins has been added. This option reduces the blocky appearance in
each bin when plotting the simulated property against the corresponding collocated property (an
inherent aspect of the cloud transform method). For an illustration, see Aspen SKUA Help > Property
Modeling > Introduction to Reservoir Modeling.
The algorithm has also been entirely reviewed, improving the visual quality of simulated properties and
the blending with the input data.
• Save distribution as text file. You can now save and reload continuous and categorical distribution
resources. Go to File > Import (or Export) > GOCAD Resources > Distribution or use the contextual
menus in the Resources browser to access the Save and Load distribution dialog boxes.
Aspen Epos V14.2 Release Notes
43
SKUA Uncertainty and HPC
• HPC Reservoir Uncertainty (Jacta Cluster) in aspenONE token mode. For Linux users, Jacta Cluster
tools are now available with aspenONE token license model.
• SKUA Uncertainty – Displaying fluid contact in cross-section. You can now display the fluid contacts
for a realization in a cross-section.
Exchanging Data
• OSDU/ETP Connector. You can now connect to a Reservoir DDMS (or OpenETPServer) using the
Energistics Transfer Protocol (ETP) and exchange data in RESQML format with other third-party
applications, such as Aspen RMS. The Reservoir DDMS is part of the Open Subsurface Data Universe
(OSDU) software ecosystem and one of the backend services aiming at storing, accessing, and retrieving
geomodelling and reservoir simulation data. Select File menu > Import (or Export) > RESQML > OSDU/
ETP Connector to access the dialog box.
• Export surface to IFC. You can now export surfaces to an IFC file. Select File menu > Export > Surfaces
> IFC to access the dialog box. The IFC format is widely supported in the building industry and allows
you to visualize surfaces created from Aspen SKUA in reference to third-party applications such as
ArcGIS or Bentley viewers.
• Export well path inclination and azimuth. In the Export Well to LAS command, when selecting Include
deviation, the Inclination and Azimuth are now exported in addition to the current X, Y deviations and
depth values. These values are recalculated according to the sampling interval. For more accuracy, use a
dense sampling.
Scripting and Automation
Improved CLI commands
• Overwrite an existing property at creation. In the Create Property command, a new option Overwrite
property has been added so you can reuse a name for a property and simplify your scripts. This option is
only visible when you open the command in the macro sequence or review the logged command in the
Log and Command Message.
• Enhanced property modeling automation. The macros to automatically build variograms and create a
property model from well logs have been improved.
Improved Developer Environment
• Python and Macro Editor shortcut keys. The shortcut keys to open, create, and save a file have been
updated for consistency between the two editors.
Tip: Press CTRL+S to save the active file or CTRL+Shift+S to save all open files in the editor.
• Python Editor output area. In the Python Editor, to ease the debugging of your scripts, the print and
exception messages are now reported in the output area of the editor. You can also clear the output at
each run.
44
Aspen Epos V14.2 Release Notes
Extended Python API
The Python API, introduced in Paradigm 22, has been extended to support more workflows:
• CLI command results. Similar to macros, when running a command script, you can now capture all
results of CLI commands and manage values with units using the Quantity object.
• Project API. Access the current project and settings with the new Project object.
• Grid API. Access the 2D or 3D gridded objects (structured only) with the new Grid object. The API
supports read and write access to properties and regions for these objects.
• Seamless Python developer environment setup for third-party applications. Configuring the
developer environment for using the Python API outside of Aspen SKUA was simplified with the new
Aspen SKUA Command-Line Interface. You can use this environment in many workflows, such as starting
the Jupyter Notebook web application or opening Visual Studio Code to edit your script with help and
auto-completion functioning for the skua module.
On Windows, use the shortcut created at installation to open a command prompt with the developer
environment variables.
On Linux, in a command prompt, execute the script in the Aspen SKUA installation path (SKUAV14.2/bin/SKUA_env.sh) to load the SKUA environment variables.
• Release notes for Python API in Help. For more convenience, the release notes dedicated to the
Python API are now embedded in the User Help. Refer to Aspen SKUA Scripting Help > Python Scripting
Interface > Release Notes to learn more about all new methods and attributes in this release.
Software Fixes
Aspen SKUA V14.2 includes a number of software fixes that further improve the product.
Foundation
• In the 3D Viewer, when you digitize a curve on top of a 2D-Grid displayed, the line now snaps to the
object from all viewpoints. Previously, this functionality was only available when you selected the Top
view.
• In the Create Tube Surface From Curve and Expansion Vector dialog box, if you append the created
surface to an existing one, the updated surface is now automatically refreshed in the view.
• In the Region Editor, you can now edit regions with spaces in their name.
• Editing the no-data value in well logs now works as expected.
• When initializing the SGrid geometry from truncated surfaces:
In the Erode SGrid by Surface dialog box, the first I and J sections are now truncated with the rest of
cells as expected.
In the Initialize SGrid Parallel to Top or Bottom dialog box, you can now use a 2D-Grid as a truncation
surface.
Aspen Epos V14.2 Release Notes
45
• In the Compute Volume dialog box, an accuracy issue related to reported volumes when the Fast
computation option was cleared has now been fixed.
• When editing the size of a Channel object for all sections, a crash was fixed.
• On Linux, you can now work with projects located on every disk data partition, even those that don't
contain the /tmp folder.
Maps, Cross Sections and Well Viewers
• When using Aspen SKUA connected to an Epos database, a crash was fixed when removing a well from a
cross-section while a map is displayed on the same page.
Interpretation Modeling
• In the Flatten Voxet With 2D-Grid dialog box, fixed a numerical instability that could lead to a crash in
some test cases.
Velocity Modeling
• In the Band-Pass Filter dialog box, smoothing well logs with no-data values now works as expected.
• For users updating a SKUA model using the Tomography method (from Pencils), the vector
displacement values are now taken into account using the default project units of measurement. For
example, Areal Unit for Delta X and Delta Y, and Depth Unit for Delta Z.
• When extracting velocity from well logs using the Extract Trend from Wells dialog box, the slope of the
trend line is now correctly calculated regardless of how the well path was initially imported with positive
values for downward or upward depth axis.
Sequential 3D Restoration (Kine3D-3)
• In the Create Point Set from Kinematic Points dialog box, you can now create a point set from any
Kinematic Mesh node regions. Previously, depending on how the region was created, it could affect how
the command worked.
• For workflow studies created in Paradigm 22 and later versions, if you had computed the strain vectors
and saved your project, you can display them again after reopening the project.
• When defining the kinematic constraints, a crash was fixed when selecting an invalid restoration target.
• In the Create Surface and PointsSet from Regions dialog box, the new object name is no longer defined
by the selected regions, which could result in long names for the created objects.
Reservoir Properties
• When using the Simple Kriging method and using a "Global mean values", the property result is now as
expected.
46
Aspen Epos V14.2 Release Notes
• When using the Cloud Transform method, the simulated properties no longer show a pixelated effect
and blending to hard conditioning data is smoother. For more information on the improvements to the
method, see New Features and Enhancements > Reservoir Properties.
• When using the Pluri Gaussian Simulation (PGS) method, an issue with fitting the truncation diagram to
target proportions has been fixed.
• When using the Multiple Point Statistics Simulation (MPS DeeSse) method, an issue to fit to target
proportions when they deviate significantly from the data proportions has been fixed.
• When creating facies map from boundaries, fixed an instability issue that could lead to a crash in some
grid configurations.
• In Reservoir Properties Workflow, the Select From Browser
option in the secondary data selectors
is now working as expected. Previously even if the property looked selected, the workflow parameter
was not properly updated, and you had to reselect the data again.
SKUA Uncertainty
• When running realizations and taking snapshots at each realization, taking screenshots of a crosssection view now works as expected.
• In the SKUA Uncertainty Viewer, plotting constant values against base case now works as expected.
Reservoir Risk Assessment (Jacta)
• In the Parameter Browser, when using a correlated property with a User Property, you no longer need to
actually create the property on the base case grid for the simulation to run.
Sharing Data
• When importing well paths from a column-based file:
If you import the path for an existing well with markers, the marker position is now updated
automatically.
If you import the path for an existing well created by another user, the well is now updated instead of
creating a new well.
• When you import from LAS files well logs that have a measurement unit corresponding to a distance,
such as caliper, and the property type name is unknown by Aspen SKUA, the imported log values are
now correct. Previously, they were shifted using the relative coordinate system of the project.
Note: As a reminder, you can add your own log names in the geolog.alias configuration file in
Aspen SKUA installation files so the well logs are automatically assigned to the right property type
when imported. To learn more, see Help and search for "Configuring Property Type Assignment to
Log Curves".
• A performance issue when importing curves from Shapefile containing integer properties was fixed. In
addition, when it is possible to store the values as float without numerical issue, these properties are
imported again as standard float properties like in Paradigm 19p1 and earlier versions.
Aspen Epos V14.2 Release Notes
47
• An issue preventing "resolve external files" when opening a project with data imported by reference was
fixed.
• When transferring a simulation grid to another project using the RESQML format, the link to a SKUA
model is now correctly rebuild if the original and target project have different relative coordinate
systems.
Sharing Data With Aspen Epos
• If you only have interpreter permissions (NO “Modify Geometry” permission) and have created and
assigned a feature to a marker in the Well Data Manager (WDM), the marker feature is now correct when
you open the marker in Aspen SKUA.
• When opening interpretation data from Epos database, an issue leading to importing two different
surfaces or curves under the same geologic feature was fixed.
Deprecated Features
In this section, you will find the list of deprecated or obsolete add-ons and functionalities in Aspen SKUA.
• The following FlexNet-based add-ons with their associated features and workflows are deprecated:
Fracture Modeling (FracMV™) is now considered a deprecated module.
GOCAD™ Structural Uncertainty (Alea™) is now considered a deprecated module. Instead, we
recommend that you use SKUA Structure Uncertainty, a more recent approach for structural
uncertainty that takes into account fault and velocity uncertainty.
Inversion Refinement is now considered a deprecated module. Instead, we recommend you use the
3D Geostatistical Operations Workflow for Interpreters in Aspen Epos Applications.
Production Data Uncertainty is now considered a deprecated module. Instead, we recommend that
you run an Aspen Big Loop™ workflow.
Production Risk Assessment Jacta–3DSL Connection and Jacta–FrontSim Connection are now
considered deprecated modules.
SKUA OpenSpirit Connection is now considered a deprecated module. Instead, we recommend that
you exchange data with the RESQML data standard.
• Solid 1.0 object is deprecated. Instead, we recommend that you use Solid 2.0 objects, which take
advantage of a more adaptable and optimized data structure.

Aspen Epos V14.2 Release Notes
49
EDIT
A problem which would cause repeated calls of the EDIT module to negate prior "editk" flag values (resetting
"yes" to "no" edit on traces) has been corrected.
GEOM2D
A warning will now be issued in the MLF if the user-provided scatter radius is larger than an internally
calculated suggestion.
HEADPUT
A problem which would yield zero values if a coordinate header was used in the ATTRI list-card has been
corrected.
Aspen GeoDepth and EarthStudy 360
New Features and Enhancements
General
• P&I HPC applications are supported on AMD Milan processors.
Note: If you are using AMD processors for running V14.2 Processing & Imaging applications, we
highly recommend using Red Hat Enterprise Linux (RHEL) version 8 as the operating system for
optimal performance. Running these applications on Red Hat Enterprise Linux (RHEL) version 7
with AMD processors may lead to performance degradation.
Create Pencils
• Create Pencils can now be run as a script for all parameters. The script can be saved in the Create Pencils
UI.
• T-surface sets and Solid models created in 3D Canvas are no longer supported in Create Pencils.
Grid Tomography
• The Grid based tomography solve stage now has multi-threaded interpolation that results in significant
performance improvements for large volumes.
The expected overall run time improvements depend on 3 factors, in decreasing order of importance
they are:
50
Aspen Epos V14.2 Release Notes
1. How much of the run is interpolation. The larger the portion of the run being interpolation, the
larger the overall performance improvement.
2. I/O capabilities. Interpolation stage is combined with I/O, faster I/O will result in a larger
interpolation stage run time improvement.
3. Memory Considerations. The maximum number of CPUs used in the interpolation stage is the same
as the rest of the run. However, if there isn't enough memory available, the number of CPUs used in
the interpolation stage will be decreased. In this case there will be a log message indicating the
performance bottleneck.
EarthStudy 360 Imager
• A new user interface has been implemented for EarthStudy 360 Imager.
This GUI is consistent with the other GeoDepth HPC applications like 3D Tomography and Kirchhoff
Migration. It includes the standard load and save script options. The parameters layout has been
improved, and redundant parameters have been removed to simplify the script setup.
Notes:
The log file was previously written by default to -mt_logfile; in the new GUI, it will be written to
-log_dir.
A saved script from the new GUI is compatible with the other GeoDepth applications and will list only
parameters that are not default.
The parameter -aux_result has been removed. Instead, set -gather_type 3 to create Reflection and
Direction angle gather outputs
For 2D surveys the parameter -line_name has been replaced with -lind_id.
Number of rays now appears in the GUI and will be saved to the script as -ray_tracing_number .
Changing opentop/openbot/diptop/dipbot/dipnum/opennum in the script will not recalculate the
number of rays (-ray_tracing_number). To recalculate the parameter, remove it from the script.
Loading a script with parameters that aren't in the new GUI, will remain in the script once saving it.
The parameters -no_slantstack, -no_statics_corr and -no_interp4 can be set only when running from
script.
A new log level, VERBOSE, which is higher than INFO, is available.
• In this release, we continued to improve the performance of EarthStudy 360 running on multiple GPU
cards. In this release multiple shots are sent in parallel to the GPU cards making the work more efficient
reducing computation time.
The GPU workload is dominated by the amount of work given to the GPU kernel. The size of work is
highly dependent on the number of valid ray pairs per point. The number of valid ray pairs is linearly
dependent on the number of shot gathers available for migration per kernel call. In previous GPU
releases a single shot gather was migrated per point. In the new version a shot gather vector is formed
that is migrated in a single kernel call. The total number of migrated ray pairs and amount of arithmetic
operations is almost identical to the previous GPU versions, however the size of the GPU kernel
increases and shows significant speedup per migrated ray pair. In addition, more CPU functions were
ported to the GPU and contributed to the overall speedup.
Aspen Epos V14.2 Release Notes
51
As the multi shot version consumes more GPU memory than the previous version, an improved GPU
memory estimation was introduced.
Environment variables related to this release:
PG_ES360_GPU_ITR_SIZE – default is 200000. The ES360 GPU workload is dominated by the amount of
data available to migrate per iteration/point or the number of available ray pairs. The performance
increases with the number of available ray pairs, but so does the memory consumption. This value sets
the maximum iteration size.
PG_ES360_MAX_NGATHERS_GPU – Default is 8. The MS version populates multiple shot gather vectors
to be migrated simultaneously by the GPU kernel. This value controls the vector size. The performance
improves with the increase of the vector size, but so does the required memory increases. The tradeoff
between memory and performance should be considered when setting the vector size.
PG_ES360_CPUS_PER_GPU – Number of CPU threads per GPU device. Default is 6. In case the GPU
memory limit is reached, meaning not enough shot gathers can be allocated on the GPU device, the
recommendation is to try 4 CPU threads per device. This could change from one data set to another
depending on the hardware specs.
• GPU Memory estimation has been added to EarthStudy 360 to optimize the GPU usage. This process
scans the size of the available free memory on the GPU device prior to the migration stage. The size of
the available memory is then reduced by a user-defined percentage that is set by environment variable
set to 20%, by default.
The available GPU memory is divided into two sections. The first holds per thread GPU memory. The
second holds multiple shot gathers. Once the per thread GPU memory is set, EarthStudy 360 calculates
and allocates the maximum number of shot gathers it can hold simultaneously for the run.
• When setting the frequency as a function of depth, the values used are now included in the log file.
P&I Utilities
• The P&I Utilities support the GeoDepth/EarthStudy 360 HPC applications (Imaging, Tomography, and so
on) allowing launch of jobs on clusters, monitoring them and viewing analytics dashboards.
Cluster settings: Defines the available clusters and cluster nodes that can be later selected in the Job
Launcher.
Job Launcher: Enables launching HPC jobs created by GeoDepth and EarthStudy 360 using a local
cluster, local machine or Slurm.
Job Monitor: Detailed monitoring of submitted jobs including progress on nodes, memory usage and
IO, as well as easy access to logs and scripts.
Analytics: Dashboards for viewing progress of projects, managing resources and analyzing
bottlenecks.
• In addition, the Image Manager and the Reporting utilities provide an easy way to create reports of the
project’s results.
Image Manager: Table listing the image sets and images that are saved to the database using the
Snapshot option in the Session Manager. Allows management of sets and images (delete, add,
rename, download).
Reporting: Create multiple slides in user-defined templates, using the images that are saved in the
database.

• Output Azimuth Filter table (multi azimuths sectors) option is not supported when Geometry Weights
and/or Offsets/Azimuth from database options are used. The combination of these options has been
blocked and an error message is printed.
• When Offset Azimuth from Database option is set to be on while Geometry Weights is off, the output
offset and azimuth cannot be read from the input seismic file. The error message for this case has been
updated to guide the user on how to run the migration successfully.
Create Pencils
• Creating pencils for 2D surveys when No Model option is selected and a Formation Table is not defined,
will work correctly. Previously an incorrect erroneous message was displayed.
• When creating pencils in Aspen SKUA , the Epos formation table is now updated and replaced with the
SKUA formation. Previously the update should have been done manually.
CRP Rays
• An issue related to displaying CRP Ray filter attributes in 3D Canvas has been fixed.
EarthStudy 360 Imager
• Amplitude normalization has been improved. Its value will remain similar regardless of the selected up
sampling value.
• The following error in the log file has been changed to a warning, as this won't cause the migration to
fail.
"ERROR: No input data traces in the workgroup range."
• The issue where using the parameter -smooth_output_gathers resulted in zero amplitudes has been
fixed.
Aspen Epos V14.2 Release Notes
53

• An issue related to Parallel read mode in Build Stage, has been fixed. Previously it failed with COMM
_RECEIVER errors.
Volume Creation and Manipulation
• When converting Interval velocity in Depth to NMO velocity in the time migrated domain, incorrect
results were produced when the time sample rate in the output file is different than the sample rate
defined in Survey Setup. This issue has been fixed.
• The transformation of Q-Effective vertical functions in Time to Q-interval velocities in depth has been
fixed.
• Interval Q-factor volume in depth is now created correctly from Q-factor vertical functions in depth.
