Rapidly deliver reservoir models with increased efficiency and confidence to make better decisions.
Expanded distance-to-failure algorithm usinguses Mohr-Coulomb failure criteria.
Use the workflow editor to automate time-consuming daily procedures so you can devote more time analyzing and characterizing the reservoir.
Machine Learning for Property Modeling combines tried-and-tested geostatistical methods with machine learning to change the paradigm of reservoir property modeling. This new process dramatically reduces the time spent on geostatistical data analysis and parameterization tasks. These time savings enable you to spend more time analyzing output property model realizations, and their associated uncertainties, to rapidly deliver reservoir models with increased efficiency and confidence to make better decisions.
Traditional geostatistical reservoir modeling is complex and time consuming. Detailed knowledge of geostatistics is generally required and the de-trending of input data, alongside stationarity assumptions, needs to be done per zone, per facies and per region. These extensive data preparation tasks are not needed in Machine Learning for Property Modeling as the geostatistical models are embedded into machine learning.
This has several beneficial implications; firstly, an unlimited number of variables can now be used to provide additional conditioning of the model. Secondly, the time normally spent on detailed parameterization can instead be spent on better understanding the geological relationships between the input and output data and gaining a more comprehensive understand of the subsurface.
Traditional property modeling efforts produce a distribution of the target property with additional effort required to gain an understanding of property uncertainty. Machine Learning for Property Modeling produces an integrated, consistent estimation of the property distribution at every cell. This allows geomodelers to obtain robust and unbiased estimates of the property, the associated uncertainty and sweet spots. These additional outputs enable you to quickly gain a better understanding of where reservoir-grade conditions are likely to be present, and where more detailed analysis is required.
In Petrel 2021.1. you can generate ensembles of VISAGE finite-element geomechanics simulations from within the Petrel platform uncertainty and optimization (U&O) process. Apply variables and vary properties to obtain a quantitative assessment of geomechanical uncertainty.
New post-processing tools in Petrel 2021.1 enable easily visualization and interpretation the output ensembles, so geoscientists can derive insights. Compatibility with the charting window enables geoscientists to present geomechanics summary findings for a selected region, individual simulations, or numerous examples in an ensemble.
The mean and standard deviation for various simulation results can be calculated and visualized in 3D using a new stress calculator tool (see picture above). The calculation enables geoscientists to determine the geomechanical uncertainty at any point in the modeled subsurface, providing a better understanding of subsurface stress and strain to enable better well placement and field development decisions
When exporting depogrid cases for simulation, Petrel 2021.1 optimizes the data footprint and runtime. For example, the export time for a 2.26 million cell depogrid, with a 25 realization Uncertainty and Optimization (U&O) workflow where properties are modified, reduces from 17 minutes (14.7 GB data) to 4 minutes (0.8 GB data).
Data will only be exported from depogrid case files if there has been a relevant change since the last export. This optimization of the data footprint means that re-export time will be substantially reduced. A further reduction in the dat"a footprint and export runtime is achieved by sharing common grid files, case data, and properties across U&O cases.
The combined optimization of the export data footprint offers a significant reduction in export runtime–a 75% reduction for a 2.26 million cell depogrid with a 25 realization U&O workflow where properties are modified–by eliminating the need to re-export unchanged and common data. Runtime savings will vary depending on the size and complexity of the model.
Identifying severely stressed faults in the subsurface is an important component of defining future field development plans, especially for EOR, carbon capture and storage, and geothermal workflows. The new distance-to-failure algorithm, which uses Mohr-Coulomb failure criteria, enables geoscientists to make an initial assessment of the fault model to identify areas of faults that are oriented favorably for slip and therefore more likely to conduct fluids up the fault.
Distance-to-failure analysis is used to determine the likelihood of sliding on individual faces of the fault surface. Fault faces that are oriented favorably for slip are considered to be critically stressed and are more likely to conduct fluids up the fault. A detailed understanding of which faults are likely to be leakage pathways is critical not only for oil and gas operations, but also for long term CO2 storage integrity and geothermal operations.
The new distance-to-failure operation in Petrel 2021.1 employs Mohr-Coulomb failure criteria and enables geoscientists to perform an initial assessment of the fault model so they can identify potential areas that may require further investigation.
The distance-to-failure operation, which is available for structural frameworks, depogrids, pillar grids, discrete fractures, and points sets, is located in the Structural analysis tab of each object's Settings dialog

After selecting and filtering the data you want to investigate, you can view spreadsheets for well logs, trajectories, point well data, completions, and more in one place without having to open each of them from the input pane. You can also get an overview of your production data, viewing bubble charts by well or by observation. The Well Data Browser is perfect for projects where you have a high volume of well data that you need to examine quickly.
Dual-porosity, dual permeability workflows are critical for static and dynamic reservoir characterization of naturally fractured reservoirs. In Petrel 2020, you can perform these workflows on depogrids, meaning you can capture complexity at every scale in your reservoir, without compromise.
Depogrid offers you the ability to model both complex and simple reservoir architecture (whether that’s complex sequence stratigraphic relationships or horst and graben structures) without compromising that complexity during simulation. Petrel 2020 introduces implicit fracture modeling for depogrids to complement the existing dual-porosity, dual-permeability workflows available using the INTERSECT high-resolution reservoir simulator. This enables you to model and simulate complexity at every scale of your reservoir.
You can also improve the reliability of your depogrid simulation model further by incorporating downhole dynamic data and generating simulated RFT/PLT logs to compare against measured RFT and PLT during history matching.
The Petrel E&P software platform now saves the size, position, and settings for the tool palette, inspector, players, and visual filters—so you quickly find the tools you need every time you open the Petrel platform.
The size, position and settings for the tool palette, inspector, players, and visual filters are saved when you close the Petrel platform, so that next time you open your session and select the tools you need, they’ll be right where you left them. The properties are not saved per project, so you can recover them for any project you open in the Petrel platform, and across multiple screens.
For the tool palette and players, the tool selection also persists. Whether you had the tools open for quantitative interpretation or facies modelling, or both, they will be restored next time you open the Petrel platform.
Combined with the ability to customize your ribbon and tool palettes, the Petrel platform offers you continuity in your work and a truly personalized user experience.

The algorithms used in the model construction process of volume based modeling have been optimized and deliver up to a three-fold improvement in runtime.
Optimizations to the model construction algorithms in Petrel 2020.1 deliver up to a three-fold increase in performance. This performance improvement affects all models, however models with large input datasets, large numbers of fault-fault or horizon-fault intersections or multiple sequences will see the most significant reduction in runtime. For multi-sequence models activating the new ‘air-interpretation’ option will further improve the model construction performance.
With the completion of the depth synthetic workflow in Petrel 2020, the software platform now offers you full flexibility regardless of the domain you’re working in.
Establishing an accurate tie from well data to seismic data is critical to ensure that all your interpretations and models are calibrated. With the completion of the depth synthetic workflow in Petrel 2020, the software platform now offers you full flexibility regardless of the domain you’re working in.
In Petrel 2020, you can add user-defined calibration points to a study, or create a study entirely based on user-defined points, giving you better control of your well tie outside of well tops. Auditability is ensured as all alignment points are recorded and stored inside the study.
In Petrel 2020 we continue to deliver performance improvements to improve your everyday productivity and reduce the number of mouse clicks and overall mouse movement you need to complete your work.
Some of the latest performance improvements delivered in 2020 include:
Ever been unable to complete an operation or workflow because data has been removed or is missing from your project? Petrel 2020.3 offers a solution to recover metadata on deleted objects or find them in the Studio platform.
Now when you come across a missing object in a workflow or operation, you can find ‘simple’ and ‘advanced’ information on an object to help you find it. Simple information includes object type, template and domain. Advanced information, which can only be exported in a private format, includes object name and import/reference project tool/Studio synchronization history. The new private format for exported workflow editor scripts ensures compliance with privacy policies and standards.
Petrel 2020.3 delivers the long-awaited ability to edit well log headers, along with numerous other visualization tools to make your work in the well section window easier.
In Petrel 2020.3 you can now customize the log name, font size, font color and apply bold, italics or underline text for improved clarity while working with well sections. Settings are saved with the well section template and can easily be applied to new cross-sections. You can also display both linear and logarithmic scales in a single track making petrophysical analysis easier in conventional workflows. Finally, you can further improve your well section display by customizing well top label styles (font size, font colour and apply bold, italics or underline text), hiding inter-well surface lines and displaying well top sub-labels between wells.
Make better-informed field development decisions by assessing reservoir integrity using the new Structural and Fault Analysis operations available on Depogrids. Consume the output fault properties directly into reservoir simulation, uncertainty, and history matching workflows to get a detailed and more accurate understanding of reservoir behavior.
To assist you in your analysis of structural model quality and fault seal behavior, we have added the following fault operations for Depogrids in Petrel 2020.3:
Dip/Dip direction
Fault throw, displacement and heave
Fault clay content prediction
Threshold pressure and column height prediction
Fault permeability prediction
Fault thickness prediction
Fault flow indicators and mean properties
Fault transmissibility scaling
A new method for calculating fault slip, utilizing the depositional space mapping, is also available for Depogrid faults. This approach significantly improves the estimation of fault properties for curved faults and around fault intersections.
Spatially varying fault properties are typically captured within fault transmissibility multipliers and exported to simulation. However, these multipliers cannot be modified in simulator history matching workflows without compromising the geological inputs behind their generation. As a result, the process of updating multipliers is prone to errors and disconnected from the reservoir simulator.
Geological fault properties generated on Depogrids can be consumed directly in the INTERSECT high-resolution reservoir simulator, offering you a new integrated fault seal analysis workflow. This workflow enables the direct consumption of geologically defined fault properties (such as permeability, thickness, and threshold pressure) in the INTERSECT simulator. In addition, a new scaling factor property is now available for uncertainty analysis and history matching workflows to accurately adjust these properties between simulation runs. This improved workflow will enhance the accuracy of your reservoir model and increase efficiency in dynamic history matching, ensuring an optimal field development plan.
EBCDIC header information is now captured and stored when you realize ZGY format seismic from SEG-Y files, greatly improving the integrity of your seismic and helping you to quickly track down source data. The saved metadata can be found in a new tab in the Settings dialog of the output ZGY data file.
When you realize ZGY format seismic from SEG-Y files, the Petrel platform will automatically save a new file in the same location as the output ZGY which contains the EBCDIC header information. The saved header information is tied to the ZGY object in the Petrel platform and can be viewed in a new tab in the Settings dialog for the ZGY object called ‘ZGY ASCII headers’. When opening the Settings dialog for ZGY files realized to an external location in previous versions of the Petrel platform, Petrel will try to collect the EBCDIC header information based on the available information.
Enhanced reservoir characterization for complex reservoir systems.
In Petrel 2020.3, a significant update has been made to the ‘Make segments’ process allowing for user-defined, repeatable grid segmentation for structural grids. User-defined parameters for fault relationships can now be set to control the virtual extrapolation of faults through their truncations. The defined parameters are stored and can be re-applied to other grids, or to properties on the same grid, to reproduce equivalent grid segments. This update also allows alternative segmentation to be applied to individual reservoir units, providing enhanced characterization of complex stacked reservoir systems.
The workflow editor is one of the most powerful tools available in the Petrel E&P software platform. Use it to automate work steps from everyday housekeeping to assessing reservoir uncertainty and share them across your organization using the new export/import functionality.
You can automate over 80% of work steps in Petrel 2020.2 using the workflow editor. Arguably one of the most powerful tools in the Petrel platform, and available with every core license, the workflow editor enables you to automate tasks ranging from everyday housekeeping (object renaming and filing) to assessing reservoir uncertainty.
