Eclipse 2001, 20th anniversary release

The 20th anniversary edition of Schlumberger’s Eclipse reservoir simulation software offers PC-based parallel processing, three-phase streamline simulation, near well bore grid refinement and a brute-force drilling location optimizer.

Jim Flynn, head of Simulation Product Planning with Schlumberger Information Solutions announced the roll-out of Eclipse 2001 – the 20th birthday edition of Schlumberger’s market-leading numerical reservoir simulator. The 2001 edition brings additions and enhancements to FrontSim, SimCube and PlanOpt.


FrontSim is Schlumberger’s streamline simulator. Streamline computation is a simplified way of computing fluid movement in the reservoir and is more suited to calculating flow in million-cell geological models than the more rigorous finite-difference technology of Eclipse. FrontSim has been extended to a three-phase black oil mode, an advance made possible by coupling FrontSim with Eclipse to generate fully implicit solutions along the streamlines.

Near well bore

NearWellBore (NWB) is claimed as the industry’s first interactive solution for fast, detailed flow modeling near the well bore. NWB uses prior full-field model results to account for flow into and out of the local volume of interest.


SimCube, an Open Spirit-enabled application, brings simulator results into GeoFrame applications. The SPE demo displayed simulator-generated attributes such as water saturation in Schlumberger’s GeoViz – along with the 3D seismic data.


PlanOpt is a brute-force calculation engine, originally developed by Agip which tests and ranks hundreds of possible drilling well locations, generating production forecasts for each hypothetical well.


The parallel versions of Eclipse 100 black oil reservoir simulator and Eclipse 300 compositional and thermal reservoir simulators are now commercially available on Windows and Linux. They can be deployed on an ad-hoc network, or on a bespoke Linux cluster. Cross-platform file compatibility means that pre-processing, simulation and post-processing can be run on different machines.


The pre and post-processor applications have seen a range of usability improvements. PVTi pressure-volume-temperature analysis software has a revamped user interface that simplifies data entry and reduces turnaround time for fluid analysis.

Real soon now!

Current development focuses on borehole geomechanics, and 4D seismic-controlled history matching with SimOpt. Integration with surface facilities leveraging the Baker Jardine acquisition is also in the planning stage. Finally, workflow integration is to be improved “so that it doesn't seem as if you are going from one application to another all the time.” That’ll be the day.
