What’s New The following tables briefly describe, by domain, the Petrel 2011.2 enhancements, including fixed issues. The companion document, Petrel 2011.2 What’s New Guide, contains detailed descriptions of any major functionality changes summarized here.

General

Feature Brief Description

Window Arrangement

You now have the choice of using Tabbed or Classic window modes:

• Tabbed - (Default) Introduced in 2011.1 to support auto-scaling, the 2011.2 version also allows you to save layouts, helping you to organize your displays for a specific workflow.

• Classic - Replaced in 2011.1, this mode was restored as an alternative in 2011.2. As in earlier Petrel versions, it supports cascading (overlapping) windows and fixed sizes.

Log File Location

Previously the default log file location was defined in the Petrel.exe.config file to be in the Petrel.exe installation area. Normal users without admin privileges were unable to write to the log files or change the settings. This issue was corrected by changing the log file location in the current and upcoming Petrel releases:

• For Petrel 2011.2 – %appdata%\Schlumberger\Petrel\2011.1\

• For Petrel 2012.1 – %appdata%\Schlumberger\Petrel\2012\

Geology

Geology Feature

Brief Description

Co-kriging Secondary Property Transformation

In the Co-kriging tab for the Kriging algorithm, if the default “No transform” setting is selected for the secondary data transformation, the result is incorrect in Petrel 2011.1. This is due to an incorrect shift-scale transformation having been applied to the secondary variable. In Petrel 2011.2, the secondary variable will be transformed according to the mean and standard deviation of the secondary property, as in Petrel 2010.

Geology Feature

Brief Description

Property Modeling

Petrel 2010.x and 2011.1 could crash while executing modeling processes on some of the newest mobile workstations (Dell M4600, M6600 and HP8760). This was because the affected processes—Gaussian Random function simulation (GRFS), Structural uncertainty, Make/Edit surface uncertainty with GRFS and Adaptive channels—used a specific Intel random number generator. The issue is solved by upgrading to Windows 7 Service Pack 1 (SP1) where the Intel bug has been fixed or by installing Petrel 2011.2 where the fixed Intel library is now integrated.

Positive Volume Cells

In 2011.1, very low volume cells (typically very thin pinched-out cells) can be incorrectly reported as having negative volumes. This is due to the limited numerical resolution of the common cell volume calculation algorithm adopted in Petrel 2011.1 for all volume computations (Volume calculation process, Geometrical modeling\Cell volume, Volume() function in the property calculator, pick cell volume in status bar). When large UTM coordinates are present, this can lead to minor inaccuracies in the computation of the cell-by-cell volume. In Petrel 2011.2, the algorithm has been fixed to work in relative coordinates, and all cell volumes are computed accurately regardless of the model spatial location.

Well Section Window

Well Section Feature

Brief Description

Discrete Log Editing

Discrete log editing is now available in all domains except for non-horizontal or recumbent wells. These types of wells still require the domain to be in Measured Depth (MD) for editing.

Display Well Section window display was corrected for errors during the following tasks:

• When removing wells or changing domain in a flattened Well Section

• During X-Section reordering when a project is reopened • When at a high vertical scale (poor performance) • When upgrading (duplicated logs)


Schlumberger Public


Brief Description

Bitmap Logs • .sif displays are now updated when the scale is changed.

• .sif files that worked in 2010 can now be used in 2011.2.

• There is now better handling of bitmap logs in the upgrade process.

• There is now support of control points for multi-segment bitmap logs.

• There is improved performance when working with control points.

• Editing bitmap logs beyond TD no longer causes an exception.

• You can now edit the first and last control points.

• An exception that occurred when editing control points has been fixed.

• There is now improved usability for deleting control points.

Comment Log • There is better handling when working with multiple comment logs.

• Comments no longer disappear when zooming in or scrolling through the wells.

• The Comment log editor now has an Apply button.

• Comment logs can now be depth shifted while the editor dialog is open.

• There is improved usability when in the Edit Existing Comment mode and the ability to create a comment at a single depth.

• Comments now fit better in the tracks.

Reservoir Engineering

• There is improved handling of simulation logs for horizontal wells.

• Updates to completions are now automatically applied in the Well section window.

Various • Discrete log interpretation is now supported in all domains, except when the domain leads to a recumbent well.

• The ability to use the SHIFT key to keep one end fixed when rescaling a well has been restored.

• Flattened well sections in the TST and TVT domains now reference to 0.

• A watermark is now available to inform users that the background data is only displayed in SSTVD and TWT domains.

• The following 2011 defects were corrected: - Issues handling invalid data and spatially unaware data from

RPT - Functional tools unavailable after magnify zoom


Schlumberger Public


Brief Description

- Slow performance when scrolling in a flattened well section - Active window not retained after upgrade - Well Section Windows not upgraded to the correct folder in the

windows tab




Several issues have been addressed following the 2011.1 release, most significantly:

• Truncation of property precision – Petrel uses the template precision to control the number of decimal places for the values in exported properties keywords in simulation export. An error is reported on export if values are truncated to zero.

• Editable relative permeability curves in a function window – This functionality has been restored following removal, to prevent accidentally changing data in 2011.1

• EPS probe – You can pick cells in a 2D window as well as in a 3D window.

Well Section: RE Workflows

• Errors in the time/dates at which simulated RFT data is displayed have been corrected.

• The Well section window adds a completion track automatically when this process is selected.

• Coloring of tubing is corrected, and individual display control improved.

• Discrete simulation results and calculated simulation results (for global grids only) can be displayed.

Studio Annotate


URLs URLs requiring authentication can now be opened from Petrel.

Studio Knowledge Database


Seismic Interpretation Transfer

The following issue was corrected: memory leaks that sometimes caused the application to allocate unreasonably large amounts of memory when transferring regional scale seismic interpretations.

Petroleum Systems Quick Look

PSQL Feature Brief Description

Make Generation Properties, Charge Modeling Processes

New functionality allows you to save created output and the settings that lead to it simply by adding another suffix to the surface attributes of a newer process run (Make generation properties) or creating a new output folder (Charge modeling).

Generation Property Output

This is new functionality in the Make generation properties process. With each calculation an additional surface attribute is generated: source rock temperature. It is listed as an attribute below the source surface on the Input pane.

Accumulation Picker

This is new functionality related to the Charge modeling process. It enables you to open the accumulation info box quickly by picking directly any accumulation in the 3D or Map View windows.

Lithologies You can now access nine extra lithologies on the Input tabs of the Make reservoir properties and Make seal properties processes. The lithologies are all varieties of shale/sandstone mixtures.

Audit Trail You can now trail the history of calculations by opening the Settings window of a Petroleum Systems Quick Look output item on the Input pane.

Overpressure Scaling Factor

In 2009 and 2010 versions of Petroleum Systems Quick Look there was an option for “Scaling factor for overpressure” in the Make generation properties process, for temperature and pressure attributes for a reservoir surface, using the same thermal scenario as for generation (in 2011.1 only hydrostatic pressured reservoir pressure was output). This functionality has been restored.

Output when Using Pepper Adsorption

When using “Pepper adsorption” as the expulsion method (on the Expert tab of the Make generation properties process), you gain additional output: “Oil expulsion mass” and “Gas expulsion mass” (in addition to “Oil generation mass” and “Gas generation mass”), since generation and expulsion are different!

Petrel Input Search Function

You can now search for any input item which has been placed into Petroleum Systems Quick Look via the blue selection arrow by right-clicking that item in the process dialog and choosing “Find in Petrel input tree”. The item will then be highlighted on the Input pane.

Capillary Entry Pressure

The default value for capillary entry pressure on the Input tab of the Charge modeling process has been changed to 20 bar (in 2011.1 it is 1000 bar).

Default Thermal Properties Process

For the Make generation properties process, on the Input tab, the thermal default has been changed from Heat flow (Basal heat flow and Thermal conductivity) to Thermal gradient.

Accumulation Settings Box

It is now possible to copy data from the table in the Accumulation Settings box and paste it into Excel or another spreadsheet.

Accumulation Settings box

The following issues were corrected:

• “Column height gas and oil’ was reported incorrectly. For example in 2011.1, if no oil was in the accumulation but there was some gas, the output was incorrectly reporting 0m.

• In the Accumulation Settings box, “IES gas and oil” has been replaced by “PetroMod gas and oil”.

• In the Accumulation Settings box, the values of IES gas and IES oil appeared under the wrong heading (gas below oil, oil below gas). This was corrected so that the value for PetroMod oil is now below Oil, and PetroMod gas is now below Gas.

• The Accumulation Settings box now fully expands to show all information without having to use the scroll bars.

Negative Burial Depth

There is now a warning message when seabed/topography surfaces/surface attributes or values and top source, top reservoir, or base seal surfaces/surface attributes cross-cut and thus result in negative burial depth.


Schlumberger Public


Charge Modeling Process

The following issues were corrected:

• Sometimes the results of charge runs with PVT using temperature/pressure maps showed subsurface (gas) volumes flashed to surface (oil and gas) volumes for some accumulations but not for others.

• Sometimes the results of charge runs when using either a map or a constant resulted in different accumulation sizes.

• Area-only charge simulation without PVT did not result in any calculations.

• A zero thickness value entered for the base reservoir still produced accumulations. This has been fixed so that no accumulations are produced when the reservoir thickness is set to zero.

Make Reservoir Properties, Make Seal Properties Processes

• When the general discrete template was used for lithology surfaces, the resulting calculated porosity had a value of 0.01 regardless of input. This issue was corrected.

• Lithology surfaces with discrete templates which had missing input for each row in the Petrel facies column of the table (on the Input tab) resulted in output of porosity of 0.01 regardless of input. This issue was corrected.

Make Seal Properties Process

There were issues with multiple data scenario output (that is, you had one scenario with different inputs and different results). Now the Options tab is no longer editable when editing an existing case.

Expanding Windows

Minor issues with expanding windows and correspondingly adjusting layout in the windows were fixed.


Schlumberger Public

Known Issues The following table summarizes known issues for the Petrel 2011.2 release.

Domain Issue Description

General: Window Layouts

• Classic window mode, supported in Petrel 2011.2, is not compatible with Petrel 2011.1.x releases: Opening a Petrel 2011.2 project that was saved with Classic window mode switched “on” will, in Petrel 2011.1.x, cause the windows to appear without borders.

Workaround: Re-start the project in Petrel 2011.2 and switch to Tabbed window mode rather than Classic window mode before opening in an earlier version.

• Window layouts defined in Petrel 2011.2 are lost if your project is opened and saved by an earlier version of Petrel.

General: Printing

If a PDF file is created when the option “Limit size of seismic bitmaps to printers/metafiles” is toggled off (Tools>>System settings>> Troubleshooting), a Seismic line will remain in the correct position within an interpretation window but be flipped in the created file.

Geophysics When doing a time-to-depth conversion (TWT to Z), the use of a seismic velocity cube indexed in depth will not produce adequate results. Instead it is always recommended to have the seismic velocity cube indexed in the domain where the transformation is initiated (not the resulting domain).

Well Section

• The Well section window does not allow you to perform any action interactively when using the log editor functionality.

• Right click context menus are not available in the Well section window.

• Unlike Petrel 2010, well data tracks without data are visible rather than hidden.

• The Well section does not recognize font changes applied in System Settings.

• In Petrel 2011.x, the template keeps the details for the display template, including details for data tracks, displayed data types, and style settings. The Well Section Window keeps details for which wells are displayed: layout, horizontal spacing, flattening, plot size, and the well tops display status.


Schlumberger Public


• The Reference Project Tool (RPT) does not support transfer of Well Section windows.

• The RPT only supports the transfer of 2011 Well section templates. To transfer templates from older projects first upgrade them to 2011.

• Well section windows cannot be copied.

• The Well section window vertical scale settings are not preserved on upgrade.

• Curve fill cannot be specified for a depth interval.

• Marker display can’t be controlled by user-created well top filters, that is, based on the interpreter.

• Bitmap logs have a refresh issue. Occasionally it may be necessary to toggle the log off and on to correct the display, and to delete internal control lines, first click on the line to be deleted and then use the DEL key.


When exporting 3D properties from the Models tree, we have found that Petrel will crash if the property name is SIGMA or SIGMAV. Exporting these properties from the Define Simulation Case Process works as expected.

Studio Collaborate

• If you add attachments to your project using the annotate workflows, then save the project (or use a previously saved project with embedded attachments), and then use the “File: Save as” option to create a new project, all attachments are lost when you open the new project.

This issue is fixed in Petrel 2012.

This issue does not occur if attachments are added as links into a project using the annotate workflows. There are two possibilities to re-import these files as copies into your project:

- Delete the file and re-add it. The history for each file can first be checked to see where the file came from. The file should not be relinked, as this will result in a linked file which appears like a copy inside of Petrel.

- Use RPT to bring in all the embedded attachments from the old project to the new project.

Petroleum Systems Quick Look

• Drainage area polygons are sometimes not complete or show strange defects for surfaces with very high resolution.

• When using the reference project tool (RPT) to move accumulations from source project to target project, the geo reference is not considered.

• Charge modeling: To ensure the right position of polylines (faults, injection polygons), the user should not use rotated maps. Workaround: Re-grid a rotated map into a north-south aligned map grid.

• Charge modeling/Input Generation tab — There might be an issue when using injection area polygons (Point/area injection) with rotated surfaces: the rotation of the surfaces may not be taken into account in the simulation run. The resulting charge modeling output may appear in the wrong position. Workaround: Use the Make/edit surface utility in Petrel to create unrotated surfaces for use in Petroleum Systems Quick Look Charge modeling.


Schlumberger Public


• Make generation maps, Base source artifacts:

- When the base source rock map is shallower than the top (intersections, negative thicknesses), Petroleum Systems Quick Look shows immature vitrinite reflectance.

- When the base source rock map is not defined (e.g. holes due to fault displacement), Petroleum Systems Quick Look calculates with a very high undefined number instead. This results in extremely high maturities and generation / expulsion masses. Workaround: Set undefined values to XXX (for example, fill hole with depth values from fault).

• When the results of more than three Petroleum Systems Quick Look Charge modeling processes are saved in a project, it can take considerable time to open the project.

Workaround for some projects: When you open a project from 2011.1 or earlier for the first time in 2011.2, save it. This may take some time, because superfluous data is removed, but the next time it will open much quicker.

• When opening old projects of Petroleum Systems Quick Look from 2009 and 2010, accumulations cannot be viewed with the intersection plane. Workaround: Re-run the Charge process with the 2011 version.

• You need admin rights to install the module.
