Schlumberger Eclipse 2026.1: Industry-Standard Reservoir Simulation Software

Eclipse 2026.1 is the latest release of SLB’s leading reservoir simulation software, featuring enhancements in tracer modeling, reporting clarity, and solver robustness for black-oil and compositional reservoirs .

Key New Features in 2026.1

Tracer Reporting Enhancements

• Water Phase Mapping: Tracers with carrier name H2O are now correctly mapped to the water phase in Eclipse 300 .

• Consistent Summary Keywords: Uniform behavior for summary keywords between Lagrangian and non-Lagrangian tracers .

• Dead Oil Handling: Tracer carriers in dead oil are treated as oil phase rather than wet gas phase .

Eclipse 100 (Black-Oil) Enhancements

• Date Handling: Improved handling of date table keywords and DATES keywords with multiple dates .

• LGR Robustness: More robust handling of local grid refinements (LGRs) and LGRLOCK .

Eclipse 300 (Compositional) Enhancements

• K-Value Generation: Improved KVGEN algorithm to reduce incorrect phase identification .

• Water Density Formula: Enhanced Trangenstein coefficients for consistency with Intersect reservoir simulator .

• Permeability Modifications: Permeability changes in SCHEDULE section can now be included in connection factors calculated after the modification .

• INCLUDE File Handling: Enhanced error handling and reporting for INCLUDE files .

Reporting & Usability Improvements

• Readable Indices: i,j,k indices with more than three digits now display clearly in PRT file messages and tables .

• Robust Output: Improved reporting for extreme numeric values .

• Reduced Duplicate Messages: Invalid SUMMARY block keywords produce fewer redundant error messages .
