Eclipse industry-reference reservoir simulator

Black oil, compositional, thermal, and streamline reservoir simulation

Overview

Robust, reliable reference simulator

The Eclipse industry-reference reservoir simulator offers the industry’s most complete and robust set of numerical solutions for fast and accurate prediction of dynamic behavior for all types of reservoirs and development schemes.

The Eclipse simulator has been the benchmark for commercial reservoir simulation for more than 25 years thanks to its extensive capabilities, robustness, speed, parallel scalability, and unmatched platform coverage.

Applications

Petrel reservoir engineering environment

The user environment for the Eclipse family of simulators is Petrel Reservoir Engineering, which integrates the static and dynamic modeling process into a seamless workflow. Data flows are transparent, with an easy-to-learn graphical user interface that supports simulation configuration and results visualization. The Petrel platform integrates data from multiple disciplines, allowing experts to combine their knowledge in a unified environment. It also supports extensive uncertainty and optimization workflows.

Better performance without upgrading hardware: Improved CPR solver brings better performance

Simulate faster without compromising results and without upgrading your hardware. Improved CPR (Constrained Pressure Residual) solver enables you to provide addition residual checks, for dramatic improvements in performance, especially when there are repeated non-linear convergence problems.

Benefits

Unrivaled depth and breadth of functionality

With over 30 years of continuous development and innovation, the Eclipse simulator is the most feature-rich and comprehensive reservoir simulator on the market—covering the entire spectrum of reservoir models, including black oil, compositional, thermal finite-volume, and streamline simulation. By choosing from a wide range of add-on options—such as local grid refinements, coalbed methane, gas field operations, advanced wells, reservoir coupling, and surface networks—simulator capabilities can be tailored to meet your needs, enhancing your reservoir modeling capabilities.

Extensive expertise and user base

Used at over 800 sites in 70 countries, the Eclipse simulator draws upon an unrivalled level of reservoir engineering expertise across the entire industry. As well as being the de facto simulation standard in the petroleum industry, the Eclipse simulator is used extensively by academia, regulatory authorities, and petroleum financial planners. Evidenced by citations in over 1,500 SPE technical papers, the Eclipse simulator is widely acknowledged as the industry’s leading reservoir simulator.

Date-ordered tabular input for satellite group production definition

The new GSATPTAB keyword has been added to both E100 and E300 to allow specification of all satellite group production information in a single keyword, with rows defined by the date they are to be applied. This is an alternative to the existing GSATPROD keyword, which must be specified multiple times throughout the scheduling data.

Direct regrouping of wells

A “direct” regrouping option that allows unconditional transfer of wells to a new group has been added. This will prove useful in several field management scenarios, such as regrouping wells to different manifolds, facilities, or production targets.

Additional inflow control device information in RFT reports

RFT reports for wells containing inflow control devices (ICDs) have been extended to include three latest items: ICD (inflow control devices) length, scaling factor, and maximum flow rates at segment conditions. These can be useful for quality checking the inflow performance for these devices and can be visualized from Petrel™ subsurface software.
