Reservoir Simulation with Petrel RE & Eclipse

Conduct a reservoir simulation study on a .PET project using Petrel RE and Eclipse to estimate production from a field with three wells, then build, run, view, and export results.

Follow a reservoir simulation workflow in Petrel RE and Eclipse, from data review and perforation to defining a simulation case with grid properties, rock and fluid properties, and results analysis.

Open Petrel with the .pet file and .ptd, and share the project as a zip. Use the Excel file for dynamic model inputs such as fluid properties and compaction.

Configure a new reservoir project by selecting coordinates, units (field or metric), and the coordinate reference system to match the field location and workflow.

Switch to the reservoir and production perspective to declutter the Petrel interface and work with inputs, cases, models, results, and workflows.

Learn to check 3D grid dimensions in Petrel RE, identify total grid cells (103,680) and spacing (50 m by 50 m), and gauge simulation compute needs.

Explore facies within the reservoir grid, identifying sand, shaley sand, and shale through the 3d window, legend, and histogram analysis, with numeric codes for rock types.

Explore porosity in reservoir models, view its continuous 0–1 distribution, and analyze statistics and histograms to understand the range from 0.12 to 0.2 with an average around 0.183.

Explore permeability in reservoir simulation, inspect grid settings and statistics, and review mean and max permeability values (750 and 1500 mD) with histograms similar to porosity.

Analyze water saturation statistics, apply a 1d filter for 0.2–0.3, invert to exclude that range, and explore 3d property slices in i, j, and k directions.

Toggle the three vertical wells afri-1, afri-2, and afri-3 to compare locations and water saturation, noting no logs and a deviation plan, and label wells as gas, oil, or proposed.

Initialize the reservoir model to equilibrium in pressure, temperature, and fluid saturation. Eclipse offers equilibration, enumeration, and restart, using reference depth, fluid contacts, composition, and zero capillary pressure.

Define a case, configure grid with permeability in i, j, k and porosity, then create perm z and perm y with the calculator for single porosity model in eclipse 100.

Explore relative permeability modeling in Petrel by applying rock physics presets for sand, shaly sand, and shale, then assign rock types to drainage simulations and compare oil–water curves.

Create a black oil fluid model in Petrel RE with light oil plus gas presets, then set bubble point pressure, formation volume factor, oil-water contacts, and initial conditions.

Select rock physics and apply rock compaction using Palmer-Mansoori or the standard methodology, input a user-defined compressibility of 3e-6 with a reference pressure around 3200 and a range of 1000–5000.

Create a development strategy in the field development tab by selecting an empty prediction strategy, using January 2025 to 2045 as dates, then save as initialization.

Navigate the advanced tab to export grids, adjust runtime options and the CPR solver, and view results in real time, then edit Eclipse keywords via the editor and runspec sections.

Discover how the results section uses default properties to automatically calculate bottom hole pressure and gas oil ratio, with options to add custom fields and reset to defaults, then apply.

Export and run your Petrel RE reservoir simulation with eclipse, define the simulation case, export, and run; initialize and QA/QC to verify oil in place and no errors.

Verify run integrity via the simulation log and print file; confirm zero production and constant pressure during initialization, and review oil in place (about 25 million barrels) in charting window.

Forecast reservoir production by perforating three vertical wells and running a new development strategy, then perform a prediction simulation to forecast oil output in a greenfield scenario.

Explore how to configure a prediction depletion strategy for reservoir forecasting, including group and well production controls, reporting frequency, and water cut rules to meet a 5000 bpd field target.

Define a forecast by duplicating the previous simulation and applying a new development strategy. Export and run; monitor reservoir pressure decline, rising gas ratio, and oil production at 5,000 bpd.

Explore common error checks in reservoir simulation with Petrel RE and Eclipse, including convergence warnings, grid connection issues, perforation coverage alerts, and how to inspect simulation logs.

Analyze reservoir performance using the results tab and charting window, compare field and well forecasts, monitor bottom hole pressure and gas-oil ratio, and study saturation dynamics to optimize production.

Create, export, and run forecast simulations with organized case naming, adjust development strategies and rates, and use WBP9 well block pressure to interpret well pressures in the charting results.

compare full-field and well-by-well forecasts to see how removing the lower perforation affects water cut, gas-oil ratio, and long-term production in reservoir simulations.

Export reservoir data and charts from Petrel RE and Eclipse to PowerPoint or Excel, including oil, gas, and water production forecasts and rates, with image and spreadsheet exports.

Explore the help center to learn reservoir engineering concepts, search for aquifers, view definitions and models, and follow steps like using the Make Aquifer dialog box.

Use the project reference tool in Petrel RE to open and compare projects, copy polygons and models between reservoirs, transfer simulation and history match cases, and interpret node counterpart icons.

Access eclipse and petrel reference manuals from the editor by right-clicking, then explore the bookshelf and keywords, or import data files to run simulations directly, without rebuilding in Petrel RE.
