Schlumberger OLGA 2026.1

Schlumberger OLGA 2026.1 is the latest release of the industry-leading dynamic multiphase flow simulator from SLB (Schlumberger), designed to model time-dependent (transient) behaviors in oil, gas, water, and CO₂-dominated systems. Trusted for over 30 years and validated by the world’s largest multiphase flow database through the Olga Verification and Improvement Project (OVIP), OLGA maximizes production potential by predicting critical operational conditions in pipelines, wellbores, and process systems. It excels in flow assurance, transient analysis for feasibility studies, field development design, and CCS (Carbon Capture and Storage) applications, supporting both offshore/deepwater and onshore operations.

Key Features of OLGA 2026.1

• Advanced CO₂ Flow Model (Olga New Solver – CCS): Dedicated high-accuracy solver for CO₂-dominated multiphase transport and injection, developed via the Olga CO₂ REACH JIP; reduces pressure drop error by 51%, hold-up error by ~31%, and improves flow regime prediction accuracy by 34% compared to the traditional friction factor model.
• Directional Leak Functionality: Calculates leaked gas and liquid fractions in stratified flow based on leak angle, diameter, and liquid level; enhances depressurization and safety simulations (compatible with the new CCS solver).
• Equilibrium Fluid Model for Pumps and Compressors: New FLUIDMODEL key with EQUILIBRIUM option using equation of state (EoS) for precise calculations, replacing ideal gas/incompressible liquid assumptions for better performance in complex systems.
• Updated Fluid Libraries and PVT Engines:
  • Symmetry™ fluid engine: Major stability/accuracy improvements for compositional tracking, flashes, P-H handling, and VLE predictions in CO₂-natural gas mixtures.
  • Multiflash library upgraded to 7.6: Enhanced cubic EoS, robust critical point extrapolation, faster initialization, and updated EOS-CG.
  • PVTsim Nova 7.2 support: Compositional tracking with PH Flash, liquid-liquid split control, and OLGA PH tab file generation (including PVTsim Nova CCS).
• Performance Optimizations: Parallel processing enhancements reduce simulation time by 2–3x (case-dependent) across most architectures.
• Transient Multiphase Modeling: Predicts dynamic changes in flow rates, compositions, temperature, solids deposition, slugging, and operational transients; supports wellbore dynamics, pipeline equipment, and integrated production systems.
• Visualization and Workflow Tools: Powerful plotting with external data import/comparison, steady-state pre-processor improvements, and seamless integration with Delfi digital platform for cloud-based parametric studies.
