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 What’s 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

What’s 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 What’s 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

For additional details, please see “Modeling” in Petrel E&P Software Platform 2013 What’s New

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

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
