Petrel 2013 With this Petrel* E&P Software 2013.3 update release, Schlumberger continues its commitment to improve and innovate the way you work. Petrel allows multi-domain experts to co-create a shared earth model that can be continuously updated as new information is acquired. These Release Notes contain short descriptors for the most significant enhancements, fixed issues, and known limitations as well as system requirements and recommendations. The full set of Petrel 2013 documentation, or documentation for any prior Petrel release, can be downloaded from the Schlumberger Information Solutions (SIS) Support Portal.

Welcome to Petrel 2013.3 Petrel continuously promotes disciplines working together and, with this release, a significant new step is introduced with the Dual Scale Modeling workflow spanning Geology and Reservoir Engineering. Other significant new features have been added in Geophysics, Production and Studio, along with performance and stability improvements. The key new features in this release are: Geophysics Surface attributes - resample option: Allows resampling of the input seismic trace prior to surface

attribute computation to address amplitude extractions in areas of dipping seismic reflectors. Interval velocity maps: The Velocity Modeling process now allows creation of Interval velocity maps directly

from the velocity model. Geology Well log calculator: The workflow for generating logs for bulk wells has been significantly improved. Well tops attributes and editing: Improvements and fixes, including allowing deletion of well tops horizons

selected in a 3D window. Log visualization: Significant performance improvements when working in 3D or Interpretation windows. Geology and Reservoir Engineering Dual scale reservoir modeling: This new reservoir model building workflow enables you to build linked

geological and simulation models that contain the structural resolution and geological property resolution necessary to characterize the static and dynamic reservoir behavior. It enables fast and accurate upscaling of grid properties between the geological and simulation grids.

Production OFM: OFM calculated fields can be imported and well mappings are preserved. Studio Web Map Gallery: Enables users to choose from a selection of pre-defined map-services. Data Synchronization: Several enhancements have been added to the data synchronization workflow. Further information on the above mentioned improvements can be found in the following sections and in more detail in the companion document, Petrel E&P Software Platform 2013 Whats New. Complete documentation for this release, and all prior Petrel releases, is available from the Schlumberger Information Solutions (SIS) Support Portal.

Project Compatibility The Petrel platform preserves the value of your historical data. Projects saved in all earlier Petrel versions will load directly into Petrel 2013 without any need for data migration. However note that projects saved with Petrel 2013 will not be backwards compatible (e.g., cannot be opened) with earlier versions.

Whats New in Brief The following content contains short descriptions of new features in this release, organized by domain. The companion document, Petrel E&P Software Platform 2013 Whats New, contains more detailed explanations, descriptions of functionality, and workflows for these enhancements.

Geophysics Feature Short Description Surface attributes: resample option

There is now an option to resample the input seismic trace prior to surface attribute computation to mitigate artifacts arising from the discrete nature of seismic. In this new release, this option is available for a few surface attributes.

Interval velocity maps In the 2013.2 release, you could create Interval velocity maps for the existing velocity model. The 2013.3 release presents an additional option to create Interval velocity maps while you are running the Velocity Modeling process. These output maps can be used for QC purposes.

Keyboard shortcut key Shift + E The shortcut key Shift + E can be used to access the Select a single point icon.

Seismic volume rendering Ray casting technology is now used for volume rendering of seismic cubes. This enables rendering techniques like depth effect for crisper and more continuous amplitude visualization.

Geobody interpretation Improved interactivity of the probe opacity manipulation.

Volume attributes: Depth conversion

Previously, assigning an Interval Velocity cube as an attribute created a cube with 0 value result. This has been fixed.

Volume attributes: Consistent dip Previously, when input seismic is in depth domain, generating the Consistent dip attribute produced random noise. This has been fixed.

Volume attributes: Favorites The issue to allow right-click on a seismic volume in the Favorites pane to access the Volume attribute process has been fixed.

Surface Attributes : Non-overlapping surfaces

Previously, generating an attribute surface between two input surfaces produced numbers with large values in areas where the two surfaces do not overlap. This has been fixed to produce an NaN (undefined) value.

Seismic interpretation: Visualize mode

Seismic interpretation commands now remain enabled when Toggle visualization on plane mode (blue button) is activated.

Seismic interpretation : Autotrack The dialog box display issue to support large fonts at 125 dpi Windows setting has been fixed.

Feature Short Description MultiZ interpretation The Create triangle mesh (Meshing) process now releases the

memory it used for calculations. In the 2013.2 release, MultiZ interpretation, in some

circumstances, rendered slowly. This has been fixed. With the Structural and Fault analysis license enabled, MultiZ

interpretation objects no longer have the Structural Analysis tab available.

Mis-tie manager Inserting Mis-tie manager on a dataset with missing intersecting lines no longer causes Petrel to crash.

SEG-Y 2D Toolbox The Shot point scalar now supports values up to 10,000. The issue for numerical precision for scaled shot point numbers

has been fixed. The issue of coordinate support for measurements in arc seconds

has been fixed. The Existing 2D lines function now correctly supports imperial

units. The loading of traces with varying time-of-first-sample (TOFS)

now activates sinc interpolation.

SEG-Y to ZGY converter The issue where certain ZGY cubes were created with checker board-like artifacts has been fixed.

Seismic Well Tie Previously, when wavelets were created using the statistical extraction method, the history was tagged incorrectly; it showed those wavelets as the extended white method. This has been fixed.

Geology & Reservoir Engineering Feature Short Description Dual scale reservoir modeling workflow

A new dual scale reservoir modeling methodology brings significant benefits for the Geologist and the Reservoir Engineer: Build a first model grid at the simulation grid resolution so that

the geologist and reservoir engineers together identify the structural resolution necessary to capture the dynamic reservoir behavior

Refine the grid, without changing the structure, in order to maximize the accuracy of well log upscaling and property population at the appropriate fine geological grid resolution

Maintain explicit mapping between coarse and fine grid for fast accurate upscaling of grid properties.

Modeling Feature Short Description Scale up well logs When running the scale up well log process, if the horizons of the 3D

grid were not perfectly tied to the well picks, there was no guarantee that the correct data was upscaled in each zone. In the 2013.3 release, a zone correction option has been added to ensure that the upscaled well data is correctly mapped to each zone.

Geology Feature Short Description Backward compatible projects We have addressed a compatibility issue between 2013.2 and 2013.1,

that may have occurred when using Annotation Style. Some projects saved in 2013.2 will not be able to be opened in 2013.1. Open these projects in 2013.3, save, and then open in 2013.1.

Geology: Wells Feature Short Description Checkshot loader When importing checkshot data exported from GeoFrame, where the

file contains a header, units can now be reset and user-specified units can also be stored for use in the next import activity.

Well log calculator There is now a seamless workflow when generating logs for bulk wells with the calculator operations in Workflow editor, so that you no longer need to delete the logs prior to operation rerun. The well log calculator no longer fails to overwrite existing logs.

Well tops attributes When computing zone thickness by using a Boolean log filter in well tops attributes, zero values are no longer produced if there are three rows in the spreadsheet. In such cases, Petrel now correctly computes the first filter interval as well as the end of each interval.

Well tops editing in 3D windows In edit mode, you can now delete well tops horizons selected in a 3D window.

Well section window display You can no longer create incomplete input data, which would otherwise result in project corruption. This fix will not correct an already corrupted project, but you can manually delete the incomplete point from the well trace spreadsheet, then save the project before visualizing in the Well section window.

Transferring wells with RPT Petrel no longer crashes if you open and close RPT multiple times when transferring wells across projects.

Log visualization in 3D and Interpretation windows

There are no longer log visualization problems in the TWT domain when you work in 3D or Interpretation windows. In prior releases, a shift resulted from the use of only time samples from trajectory points. Now all time samples interpolating the trajectory at each sample are used to visualize in the TWT domain.

Well Section Window Feature Short Description Reference Project tool The transfer of Well section windows and cross section objects is now

possible using the Reference project tool for Petrel project versions 2013.1 and onwards. You need to upgrade your projects to at least the 2013.1 version to use this feature.

Plotting The SDI_Print failed error has been fixed when trying to plot a cross section hardcopy.

Well Tops Several use cases that caused well tops not to display in the cross section have been fixed.

Well Design Feature Short Description BHA display in Well section window

You can now hide a BHA display in the Well section window by clearing the depth settings for the BHA. You can also display the BHA as a depth line by setting the same start and end depths.

Production Feature Short Description OFM - Importing from OFM OFM calculated fields can be imported.

OFM - Petrel 2013.1 OFM Data Connector Templates

Well mappings are preserved when an OFM Data Connector template from a 2013.1 project is used in a 2013.2 project.

Production Analytics - Split Sets Split sets can make the round trip from 2013.2 to 2013.1 and back to 2013.2.

Well Deliverability - Petrel Projects with TUFFP Flow Correlations

Because the TUFFP Unified 2-phase v2007.1 flow correlation is no longer supported by Petrel and PIPESIM, you will receive a warning message if you try to open a Petrel project that was saved with a TUFFP Unified 2-phase v2007.1 flow correlation.

Reservoir Engineering Feature Short Description Exporting multiple realization cases

Exporting multiple realization cases no longer include the MULTREAL keyword when exported outside either the Workflow editor or Uncertainty and Optimization process.

Specifying the simulator version when exporting a data set containing the WSEGVALV keyword

If your version of ECLIPSE is earlier than 2013.1, you must specify the simulator version when exporting a data set including the WSEGVALV keyword.

Studio Feature Short Description Web Map Gallery A new Webmap Gallery has been added, which enables users to

choose from a selection of pre-defined map-services.

Data Synchronization Enhancements have been added to the data synchronization workflow. These enhancements include the option of using a filter to control what data is selected from the database and the ability to only send new items with particular data statuses.

Re-parented 3D interpretations displayed polygon only in Find

This issue, described in the 2013.2 Release Notes, has been resolved in 2013.3.

Known Issues The following content summarizes known issues and limitations for this release, grouped by domain.

Structural Framework Affected Feature Issue or Limitation

Volume Based Modeling (VBM) Method

Baselap-baselap relationship is not working as expected. It is not possible to explicitly define truncation rules between unconformities: the youngest unconformity is always assumed to be truncating older unconformities.

The stair-step faulting process is disabled when using faults coming from a VBM model.

Eroded horizon surfaces coming from VBM models are not always handled properly in pillar gridding. They may be extrapolated beyond erosion line.

Results are not fully reproducible, especially in areas where there is no input data to control horizon extrapolation. However, differences in volume are expected to be less than 1% in areas where data interpolation is properly constrained.

Zones could present visualization/rendering issues reflected as empty triangles in Interpretation window, Intersection planes and Intersection window.

Geophysics Affected Feature Issue or Limitation

Seismic Compression Volume attributes generated from compressed cubes may display cosmetic artifacts along its edges. These edges are typically zones along boundaries of irregularly shaped surveys, muting zones at edges of surveys and zones above sea bottom which in the compressed cube borders consecutive neighboring samples with zero values.

WORKAROUND: These cosmetic artifacts can be cropped from view. Alternatively crop the compressed cube prior to generating volume attributes. For compressed cubes intended for more permanent storage, we recommend to (re)generate these using the next release of seismic compression process.

Velocity cubes and other non-zero mean (e.g., positive only values) data types should be compressed with a high (enough) value SQNR to maintain adequate signal quality.

Affected Feature Issue or Limitation

SEG-Y 2D Toolbox Upon clicking Define byte location, the Message log shows "Unexpected error occurred when resizing BinatryHdrGridview Exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". This message can be safely ignored. This message appears when working in a Windows environment where text size has been set at values other than 100% of normal size.

WORKAROUND: Set Windows text size to 100% of normal size via Control Panel > Appearance and Personalization > Display.

MultiZ interpretation MultiZ interpretation is not yet supported within the Studio Environment.

Seismic operations run from the Operations TAB of the MultiZ Interpretation cannot be undone.

MultiZ interpretation projected point can become disconnected with the segment on the section (e.g., inline) while editing it on the crossing section (e.g., crossline).

The restrict mode is not available in the 2013.3 release.

WORKAROUND: Use Flip in front of/behind plane instead.

Seismic Well Tie The new version of Seismic Well Tie uses the Petrel domain conversion algorithm, while the old version used a proprietary algorithm; hence, small numerical differences are to be expected.

For every study, a temporary folder and objects will be created and stored under the Input tree; they will be located under the Well > Study Folder > Visual. This folder should not be deleted.

When wavelets created in the Wavelet Toolbox are copied (using Copy/Paste), the parameter settings for this new wavelet cannot be edited.

Deleting any required input data belonging to the Study from the Input tree will close and delete the current study. All the objects saved from the study will still be preserved in the Input tree.

If a seismic, log or wavelet used in an SWT study is deleted, the SWT settings will be auto-populated with the next available object with the same template.

Deleting the Well Section Window study will delete the information inside this study and temporary objects created for visualization. All the objects saved from the study will still be preserved in the Input tree.

Exploration Geology Affected Feature Issue or Limitation

General After copying/pasting a Play Chance Mapping, Prospect Assessment, Prospect Summing, Petroleum Systems 1D, or Petroleum Systems 3D object on the Input pane, the Edit existing area in the process dialogs is not updated immediately, i.e., does not show the copied object (only while the process is open).

Petroleum Systems Quick Look General

When opening old projects of Petroleum Systems Quick Look from 2009 and 2010, accumulations cannot be viewed with the intersection plane. Re-run the Charge process with the 2013 version.

Make generation properties Rotated surfaces which were entered and resulted in an error message, when removed from the dialog still produce an error message.

Make generation properties When the base source rock map is not defined (e.g. holes due to fault displacement), it results in extremely high maturities and generation / expulsion masses. Ensure holes in the map are filled, for example by using the depth values from fault.

Play Chance Mapping Discrete surfaces are not supported by Play Chance Mapping, using a discrete surface as a property surface can lead to a Petrel crash. WORKAROUND: Use discrete surface attributes.

Imported PetroMod overlay: Gas content

There are differences in the definition of gas content in Petrel (mass/mass) and PetroMod (volume/mass) resulting in the wrong visualization of the overlay. Do not use this overlay.

Templates and units for "Temperature/Heat capacity" data

Petrel and PetroMod used different templates and units for "Temperature/Heat capacity" data. When PetroMod overlay data was imported using "Convert to simple grid in the 2012.1 release, units were incorrectly converted. This is still an issue when you open overlays which were imported using 2012.1 versions, even with the 2012.2 or 2013.1 version installed. WORKAROUND: Re-import any overlays that were previously imported.

Fracture Modeling Affected Feature Issue or Limitation

Large 3D grids An observation grid (reservoir grid) with more than one million cells will take approximately 10 minutes to compute during the Generate Fracture Driver process.

Fold related fractures Models with fold-related fractures cannot give coherent results since the methodology is based on fault-related fractures.

Well Design Affected Feature Issue or Limitation

Well plan display in an intersection window

If an Intersection window is associated with a curved surface, the display result of certain plans might be incorrect.

Converting a simple proposed well to an advanced plan

A simple proposed well is created with Well path design by manually digitizing the design points. When converting a simple proposed well to an advanced plan, the design points will be converted into Station points in the advanced plan. If you click Go to surface or add any curve section to the top in

Well path designer, for the Station points, only MD, INCL and AZIM values will remain unchanged during calculation, but X, Y, Z and TVD will be recalculated.

If the last point of the simple well (TD) is above MSL, the conversion will fail due to TVD and MD being referenced to MSL instead of to Kelly Bushing (KB).

WORKAROUND: Edit settings for the proposed well by changing from simple well to standalone well with appropriate KB value.

Associating a side track to a well When assigning a branch to a main well during the sidetrack creation workflow, the trajectory of the main well (parent) and the branch (sidetrack) must be within 1m. Otherwise, the assignment will fail.

Well path creation with non S-3D profile

The system automatically converts any non S-section (profile) into an S-3D profile when you click on that section in a 3D window and in well path design Pick/Dragger mode. The conversion will display in the Well path designer spreadsheet as empty rows. Those rows will be filled up when modified with the dragger. WORKAROUND: Click the Undo button and return to the Well path designer.

Plan grid convergence values In the 2012.1 release, if a project was set up with mixed units, the grid convergence for the plan might be calculated incorrectly. This issue was fixed in the 2012.2 release. However, if a project is saved with the 2012.1 version and is opened with any newer version, an incorrect grid convergence will occur. WORKAROUND: To correct this, you must trigger a plan recalculation by editing the plan (with Well path designer, dragger or Inspector) in a 3D window.

Transferring data over different index ranges

For some particular data sets, when one incoming log in the server contains multiple passes of data over different index ranges, if the deeper data range is downloaded before the shallower or earlier data range, the shallower or earlier data might be skipped during data transfer. For more details, see the online help.

Production Affected Feature Issue or Limitation

Different TVD for Deviated Wells in Petrel vs. PIPESIM

Petrel and PIPESIM use different algorithms to calculate true vertical depth (TVD). As a result, when you import a deviated well from PIPESIM to Petrel, the TVD values will be slightly different in the two applications. Petrel imports Measured Depth (MD) values exactly as they are in PIPESIM, but Petrel uses a more advanced algorithm that allows for curved paths. True vertical depth is then derived from the MD values. WORKAROUND: If you want your TVD values in Petrel to match the same well in PIPESIM, after importing the well from PIPESIM, you can export the well deviation data, then manually correct (key-in) the TVD values in the deviation file, then re-import the deviation values. This effectively forces the TVD values rather than deriving them from the MD values.

Well Section Window Production charts may be positioned incorrectly in a Well Section Window. WORKAROUND: In a Well Section Window, you must display a production chart in the MD domain for the chart to be positioned correctly.

Reservoir Engineering Affected Feature Issue or Limitation

RESQML files exported from Petrel 2012.1 cannot be re-imported into later versions of Petrel.

RESQML format files that had been exported from a Petrel 2012.1 project cannot be re-imported into any version of Petrel from 2012.2 onwards. This issue is caused by changes the underlying storage technology. WORKAROUND: To access the grid and properties in a 2012.1 RESQML file first import the file into 2012.1, then upgrade the 2012.1 project to the newer version of Petrel (2012.2+), and then re-export RESQML. The re-exported RESQML file can then be read by newer versions of Petrel.
