Schlumberger ECLIPSE v2025.3
The ECLIPSE family of simulators provides the most comprehensive and reliable set of solutions in the industry for numerical simulation of the dynamic behavior of all types of reservoirs, fluids, degrees of structural and geological complexity, and development systems.

ECLIPSE covers the full spectrum of reservoir modeling tasks, including finite difference models for crude oil, dry gas, gas condensate composition, thermodynamic models for heavy oil, and flowline models. By selecting various add-on options from the widest range available (e.g., coalbed methane modeling, fuel calorific value production control, onshore gathering network modeling), you can add everything you need to fully meet your modeling needs, expanding and deepening your understanding of field development issues. For over 25 years, the ECLIPSE simulator has been the benchmark commercial product for development modeling thanks to its unmatched breadth of capabilities, stability, speed, parallel computing scalability, and compatibility with a variety of software platforms.
