The Petrel E&P software platform offers geoscientists and engineers a single platform for collaborative workflows with best-in-class technology and leading innovation. From seismic processing to production, the Petrel platform enables seamless integration across all subsurface domains, enabling you to deliver your best field development plan.
Our commitment to technology and quality is one of Schlumberger’s guiding principles. Petrel 2021.2 delivers the latest updates in domain workflows, functionality, and productivity. It also leverages the power of the DELFI cognitive E&P environment’s data ecosystem to bring the latest advances in cognitive technology to your favorite E&P platform—whether you’re working in the DELFI environment or on premise.

Machine Learning for Property Modeling
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.
Only available in the DELFI Petrotechnical Suite.
DATA AND FOUNDATION
Focus on your area of interest (AOI) and avoid accidentally moving a display with the new ability to create a fixed AOI based on scale and coordinate position. With this enabled, it is not possible to pan or zoom in a map window, making printing and positioning workflows much easier. AOIs can also be shared via the reference project tool.
Growing and shrinking polygons by a specified distance can now be done without producing spikes in the output polygon. The rewritten algorithm also aims to avoid creating inside-out polygons when shrinking a closed polygon.
EXPLORATION
Petrel 2021.2 now writes all ZGY files using the OpenZGY library that Schlumberger donated to the Open Subsurface Data Universe (OSDU) in 2021. The OpenZGY library is an OpenSourced version of the ZGY library that the Petrel platform has used for more than 15 years. The adoption of the OpenZGY library in the Petrel platform also enables the creation of compressed OpenZGY files, reducing the amount of space required for storage. OpenZGY files can be easily consumed by third-party software that also utilizes the OpenZGY library.
Live collaboration functionality, i.e., the real-time sharing of objects between users, has been further enriched in Petrel 2021.2 and now supports 2D seismic interpretation and polygons. This builds on the already shareable well tops, surfaces, points sets, and 3D seismic interpretation objects (with improved performance in this release), enabling enhanced collaboration within the Petrel platform.
It is now possible to quickly calculate thickness, percentage, and fractions for interzone layers within well tops. This long-awaited functionality is delivered alongside a raft of new features for the well section window aimed at improving everyday usability. These include but are not limited to coloring point well data by attribute, copying tracks between well section templates, and changing the color of the ghost curve. For full details check out the release notes.
Filtering information in the well tops spreadsheet has never been easier. The new abilities to display the unique well identifier (UWI) alongside well names and hide spreadsheet columns help you find and focus on the information you need.
When importing derived logs into the Petrel platform or updating existing derived logs from the Studio E&P knowledge platform or a reference project, you no longer need to rerun the derived log operation, as this is done automatically after one-click selection. This removes the need for you to repeat work steps post-update and enables you to focus on the interpretation work that matters.
Median, Bartlett, and Hamming smoothing algorithms are now available in the Petrel platform, offering alternative weighting options for data points in the smoothing radius. In addition, you can now input a fault polygon to a surface smoothing operation to avoid surface dragging around the fault and preserve the data within the polygon.
DEVELOPMENT
Gain a better understanding of the interaction between reservoir and aquifer with improved aquifer workflows for depogrids. With numerical aquifer support for the Petrel platform and INTERSECT high-resolution reservoir simulator, consumption of user filters, copy/paste of grid aquifers into target grids (of all types), and visualization improvements, you can enhance subsurface modeling accuracy and enrich reservoir insights.
Perform comprehensive analysis of your reservoir structure by using new tools now available on depogrid, including the addition of grid properties to faults and the creation of high-quality 2D fault plane diagrams. A new fault threshold pressure prediction global equation using Yielding et al. 2010 (also now available for pillar grids and stairstep grids) assists you to define fault threshold pressures based on the fault/fluid properties and maximum burial depth of faults in analogous areas.
The modeling of naturally fractured reservoirs using implicit fractures was enabled for depogrids in Petrel 2020.1. To further supplement this workflow and improve the consistency between input density distribution and fracture model output, the fracture density process has been extended to support the use of depogrid horizons as mechanical boundaries.
In Petrel 2021.2, you can now create geomechanics ensembles based on a two-way coupled simulation between the VISAGE finite-element geomechanics simulator and ECLIPSE industry-reference reservoir simulator or the INTERSECT simulator using a new option that enables the creation of copies of reservoir engineering cases. This expands on the Petrel 2021.1 ability to generate VISAGE simulations from within the Petrel platform uncertainty and optimization process.
Improve collaboration with extended support for geomechanics related objects. Geomechanical grids, pressure definitions, boundary conditions, fault and fracture mappings, and postprocessing analyses such as from the stress calculator and mud weight prediction can now be transferred using the reference project tool (RPT).
Take advantage of greater flexibility delivered in Petrel 2021.2 for permeability updating functions. Two-way coupled simulations can now be generated solely based on strain or displacement changes without considering a specific initial opening.
SIMULATION
Simply implement economic input logic for certain common operations to automatically generate the required lists (static/dynamic), actions, and instructions internally in the INTERSECT simulator at runtime. You can now use Field Management in the Petrel platform to create an economic logic template that helps define a simple logic to perform automatic workovers. To use this new functionality, you must select INTERSECT Connector 2021.3 or later.
In Petrel 2021.2, you can now choose between six different viscosity mixing rules when creating your thermal fluid model to capture the required effect in your INTERSECT simulation models. This enables you to better capture phenomena occurring during thermal enhanced oil recovery operations. To use this new functionality, you must select INTERSECT Connector 2021.1 or later.
To model the pressure and temperature dependency in the component molar enthalpy in INTERSECT simulation cases, you can now choose between using enthalpy calculation equations or directly providing tabular data as a function of pressure and temperature when creating your thermal fluid model. This is important for modeling solvent injection with SAGD cases or for CO2 injection where phase enthalpies vary with pressure and temperature. To use this new functionality, you must select INTERSECT Connector 2021.1 or later.
You can now transfer streamline data generated by the Petrel platform or the INTERSECT and ECLIPSE simulators between projects using the RPT. You also can now import and export thermal dead oil fluid models as IXF files into and out of the Petrel platform.
The Petrel E&P software platform and Studio E&P knowledge platform bring benefits to all geoscientists and engineers, including seismic processors, seismic interpreters, geologists, reservoir modelers, reservoir engineers, drilling engineers, production geologists, and data and information managers. They can be deployed by companies working in exploration, development, and production for either unconventional or conventional reservoirs.
