Eclipse 2026.1 (One PC)

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