Schlumberger ECLIPSE v2025.1
The ECLIPSE family of simulators provides the most comprehensive and reliable 
set of solutions in the industry for numerical modeling 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, composite 
gas condensate, thermodynamic models for heavy oil, and flowline models.
 By selecting various add-on options from the widest range 
(e.g., coalbed methane modeling, production control based on 
fuel calorific value, onshore gathering network model), you 
can supplement the simulator's capabilities with everything you need to fully 
meet your task requirements, expanding and deepening 
your understanding of the issues involved in field development. 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.
