Well section window

Performance improvement in Well section window: General performance improvements in the Well section window when moving, reducing, maximizing, or restoring a window with many wells displayed. Performance improvement when displaying logs with high density data with color fill.

Petrosys map window

The Petrosys map window now supports the creation of bubble maps for wells and well tops attributes. Additionally, the Petrosys map window has improved support for international characters throughout.

Structural Modeling

Structural Framework Modeling

Structural models computed in Petrel 2020.1 are expected to show slight variationsfromthosecomputedinpreviousreleases,particularlyinsparsedataareas.Thesechangesarerelatedto thealgorithmicchangestoenhanceperformanceandareexpectedtobemoreconsistentwithinterpretedstructures.
• ImprovedconsistencyoftheDepospacegeometricalflatteningmethod:Insomecases,inconsistentrotationofthe structuralmodelsindepospacewasobserved.Thisrotationwasrelativetothegeospacerepresentation.Thisisnow fixed in Petrel2020.1.

Implicit fracture modeling support for depogrids: The modeling of naturally fractured reservoirs using depogrids has been enabled in 2020.1. This complements the existing dual-porosity, dual-permeability simulation workflows available on depogrids using INTERSECT. The Fracture network and Scale up fracture properties fracture modeling processes are currently supported. The Fracture density and Generate fracture driver processes are not active for this grid type.

• Improved'ODAcorrected'fracturepropertyupscalingmethod:TheODAcorrectionhasbeenmodifiedinPetrelPreviouslyitwasonlyvalidforcertainrangesofextendedconnectivityindex,eCl,andlength,L.WitheCIlowerthan

~26-27 and L lower than ~0.7, it was noticed in some specific cases that upscaled permeability would decrease as the eCI connectivity increases due to the fracture network generating values of eCI,L outside the expected range. This is now fixed.

Gridding

Depogrid layering enhancements: Algorithmic enhancements have been made to the Depogrid creation process to improve the grid layering proportionality. These changes reduce the number of self-intersecting cells. This enhancement can be observed in certain model configurations, particularly those with very high aspect ratio cells.

Geomechanics

Reservoir Modeling

General

Convert property to points: You can now convert properties to points, with attributes that represent the property values. This feature is available in the context menu of an object, on the Operations tab in the Settings dialog box for an object, and in the Workflow editor.

Workflow Editor

Insert quality assurance map: An option to insert a quality assurance map is available in the Workflow editor. You can find commands for inserting maps in the Insert quality assurance map folder under Processes.

Train Estimation Model

Output neural net classification probabilities to variables: When using neural net as the method for facies modeling in the Workflow editor, the resulting classification probabilities can be assigned directly to variables. Select the Output probabilities checkbox to enable Open variables table.

Guru

Guru Content Manager

Projects download functionality removed: Within Guru Content Manager, the functionality to download projects from the cloud has been removed.

Foundation

Annotate Note

Annotate Note enhancements: The Annotate Note's interactivity and functionality have improved and you can now preserve your note's position and your display status choices. These settings are saved and recovered when you reopen the project.

Floating Widgets

• Propertiesoffloatingwidgetspersist:Petrelnowsavestheposition,size,andsettingsforthewidelyusedfloating widgets, whichinclude:
  • Toolpalette:Positionandgearsettings.
  • Inspector:Position,size,andgearsettings(withtheexceptionof'Window',becausethisisprojectspecific).
  • Players: Position and gearsettings.
  • Visualfilters:Position,size,andgearsettings.

Your choices for these tools are saved before the Petrel session is closed. When you start a new Petrel session and select any of the last used tools, they are positioned on the last place they were left on any monitor, together with the size and specific settings, whenever applicable.

Properties are saved locally in your machine and they do not depend on a specific project, so you can recover the saved properties every time when using Petrel, which enables a personalized user experience.

• Selectionoffloatingwidgetspersists:Petrelnowsavestheselectionoftoolsfortheapplicablefloatingwidgets, whichinclude:
  • Tool palette: tool groupselection.
  • Players: playersselection.

Your selections for these widgets are saved when you save the project. When you reopen the project in a new or existing Petrel session, the last used selection of tools is restored, which improves usability, workflow continuity, and creates a personalized experience.

Improved workflow to define the project CRS

When you create a new Petrel project, the box to define the spatial context now appears when the project is created. This is to organize the workflow to create a new project, and prevent the box appearing unexpectedly. If Petrel is completely initialized, it now appears immediately when you click New project.

Polygons and Points Attribute Spreadsheet

Polygons and points attribute spreadsheet improvements: In the polygons and points attributes spreadsheet, you can now perform a multi-selection of cells belonging to a single column and select on or off. This is applicable for Show and boolean attributes.

Position Groups in Viewports and Windows

Position group new linking functionality: In selected viewports and windows you can synchronize the position to a specific group, so that panning and zooming the display in the active viewport or window has the same effect in the other
