Eclipse simulator

Robust, reliable reference simulator

Overview

The Eclipse™ reservoir simulator offers the 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 40 years due to its robust capabilities, speed, parallel scalability, and unmatched platform coverage. The simulator covers the entire spectrum of reservoir modeling, including black-oil, compositional, thermal, and streamline simulation.

Eclipse 2025 features

Eclipse 2025.1 release announcement

Date-ordered table input for group injection and production definition

The new GTABPROD and GTABINJE keywords have been added to both Eclipse 100 (E100) and Eclipse 300 (E300) to allow concise specification of all group production and injection information in single keywords, with rows defined by their date of application. This is an alternative to the existing GCONPROD and GCONINJE keywords, which must be specified multiple times throughout the scheduling data.

Improvements to new energies workflows

Improvements have been made to support cases with component solubility in water defined by CO2SOL and H2SSOL keywords. Firstly, the default water density calculation now uses the Ezrokhi's method, a standard in such cases. Solubility calculations now employ exponential expansion for more precise interpolations of formation volume factor and viscosity.

Enhanced reporting for summary keywords

Several enhancements have been made to line plot reporting in this version:

The well name can now be defaulted for summary keywords starting with S, to produce output for all multi-segment wells.
In E300, the group name can now be defaulted for group summary keywords which take a component number to produce output for all groups.
