The Petrel* E&P software platform enables reservoir engineers to collaborate effortlessly with each other as well as with geoscience and production specialists. Combining knowledge from all these disciplines into a single, model-centric subsurface representation means that changes in the seismic interpretation or geological model cascade through to the simulation model. Changes dictated by simulation studies flow back into the subsurface interpretation and model, while integrated production data allows subsurface models to be kept easily in sync with the latest operational information.

Powerful reservoir simulation environmentPetrel Reservoir Engineering provides a fully featured pre- and postprocessing reservoir simulation environment, supporting the ECLIPSE industry-reference reservoir simulator and the INTERSECT next-generation reservoir simulator. Easy-to-use workflows and powerful visualization capabilities make the Petrel platform an efficient and productive environment for reservoir engineering workflows.

Advanced gridding and upscalingThe Petrel platform offers a variety of gridding and upscaling techniques for resampling fine-scale geological models to simulation-ready models. Gridding techniques include corner point grids for full fields, stair-step (IJK) gridding for complex faults (e.g., highly inclined or Y faults), as well as both structured and unstructured local grid refinements (LGRs) for challenges associated with coning, and horizontal and multilateral wells. Upscaling includes a suite of averaging methods and a flexible tensor function, to determine effective permeability in each simulation cell.

Results charting and analysisPlotting charts of simulation results and production forecasts is daily work for most reservoir and production engineers. Petrel Reservoir Engineering provides a dedicated process for simulation charting that gives greater control and reusability, allowing users to get high-quality charts for reports and control how charts display, as well as share and reuse the charts and templates on the next simulation, project, or asset. Engineers can also see the same data in different ways to get more insight into their simulation, and play equivalents charts to compare different wells or groups in a field.

INTERSECT field managementThe INTERSECT simulator supports flexible, advanced field-management capabilities, such as optimization of rigs and other resources by specifying complex strategies with constraints and conditional logic. The Petrel platform provides a straightforward interface to easily configure and control these advanced workflows.

Better, faster decisionsUnderstanding the impact of uncertainty on your reserves estimates and production forecasting is essential to making the right field-development decisions. The Petrel platform provides straightforward workflows to quantify and understand uncertainty. It also makes advanced workflows quicker and easier, allowing engineers to work more productively and arrive at better decisions—faster.

Geological model screening and rankingStarting with the geologic model and uncertainty ranges for various parameters, the Petrel platform quickly generates multiple geological realizations that are all consistent with observed data constraints. FrontSim* streamline simulations let you create recovery profiles from multiple models quickly—these are then used with static volumetrics to screen and rank multiple geological realizations.

Uncertainty and sensitivity analysisThe Petrel uncertainty manager lets you create, submit, and analyze a large number of simulation runs and proxy model solutions. Workflows can be used for both dynamic simulation cases and static volumetric cases, and are essential to understanding the impact of uncertainty on hydrocarbon recovery. Flexible cross-plotting and tornado charts provide extra insight into results.

Streamlined history matchingHistory matching is essential to continually improve the predictive capability of reservoir simulation models. This process can be time consuming and difficult when there are multiple wells, data types, and properties to consider, and hundreds of simulation runs to be managed. The Petrel platform streamlines this process, enabling you to define a history matching objective function, as well as providing dedicated data-management and sophisticated run-management systems. A range of global optimization algorithms and analysis tools let you quickly isolate the most likely realization and arrive at the best history match.

Optimization of well path and completion designThe Petrel platform provides advanced well-handling capabilities with automated placement and completion optimization. You can easily design complex wells, such as fish-bone and fork wells, and place them inside geological bodies with precision. In addition, the Petrel platform supports design of advanced completions such as inflow control devices (ICDs) and flow-control valves (FCVs). The platform also now supports complex well modeling to keep pace with the evolution of completion designs. Sliding sleeve devices, which allow individual branches of a multilateral well to be shut, are now modeled, visualized, and configured for reservoir simulation. With these comprehensive well-design tools and uncertainty and optimization workflows, you can evaluate and optimize well placement and spacing, as well as the type and number of laterals and completions.

MEPO plug-inThe uncertainty and optimization capabilities of the Petrel platform can be extended by use of the MEPO* multiple realization optimizer. The integration between Petrel platform and the MEPO optimizer has been enhanced to provide easier access to running advanced simulation-intensive workflows directly from the Petrel platform. The MEPO plug-in provides a powerful toolkit for better understanding reservoir behavior and parameter dependencies, and improves the probabilistic nature of both greenfield and brownfield project deliveries.

Reservoir geomechanicsGeomechanics phenomena—including subsurface stresses, rock deformations, and failure—have the potential to adversely impact exploration drilling, well survivability, field development, and production operations. The Petrel platform provides an efficient, integrated environment for geomechanics modeling, enabling 3D preproduction geomechanics modeling that allows experts and non-experts alike to incorporate geomechanics analyses into their existing reservoir or structural models.

Coupling these geomechanics models to reservoir simulation also provides 4D analyses and predictions of stress changes, deformations, and rock failure that might occur later in the life of their field. Two-way coupling between the geomechanics simulations and ECLIPSE reservoir simulations provides permeability updating of reservoir models, predictions of enhanced permeability for regions of rock failure, and geomechanics property updating with changing stresses, temperature, and water saturations. Engineers can assess potential changes and deformations in the reservoir overburden formations throughout the entire field life that impact

■ well and completion survivability ■ the potential for solids production ■ inadvertent loss of reservoir containment and out-of-zone injection ■ fault movements ■ changes in reservoir characteristics and performance ■ induced rock failure and seismicity.

Unconventional reservoirsDevelopment of shale gas, shale oil, and coalbed methane plays has increased dramatically over the past few years. The Petrel platform provides a dedicated interface for defining the physics specific to modeling these types of reservoir. Preset models and parameter values are available, including Langmuir isotherms and pressure-dependent adsorption functions, as well as a Palmer-Mansoori rock-compaction model. The full ECLIPSE compositional coalbed methane model is also supported, including component-dependent extended Langmuir models and the multiple-porosity matrix model. With the high well count required in these unconventional developments, automated workflows plan optimal well placements based on both surface constraints and reservoir quality assessments, supported by two Ocean* software development framework plug-ins: Pad Placement and Pad Well Design.

Integrated production dataThe Petrel platform provides easy access to production histories via a connection with OFM* well and reservoir analysis software, which supports integration of production data from both the well and completion level. Production geologists can now incorporate dynamic simulation and production data using new production analytics capabilities for well performance analysis, to better diagnose production losses or trends. Visualization techniques (e.g., bubble mapping, production grid mapping, and a well section window track for production) integrate the production history into the earth model, providing an integrated environment for relating the actual well production back to the geology.

The Petrel Well Deliverability module enables reservoir engineers to validate and tune reservoir simulation models using hydraulic vertical flow performance (VFP) tables and nodal analysis. Reservoir engineers can then evaluate and choose optimum well completions or predict well productivity, based on the impact of mechanical changes and workovers on well inflow performance. Nodal analysis capabilities record operational factors used in a simulation run and identify possible problems using the data in context with the reservoir model.
