Schlumberger OLGA 2026.2 – Advanced Dynamic Multiphase Flow Simulation Software
Industry-Leading Dynamic Multiphase Flow Simulator
Schlumberger OLGA 2026.2 (developed by SLB, formerly Schlumberger) represents the latest evolution of one of the world’s most widely used dynamic multiphase flow simulation software platforms for the oil and gas industry.
For decades, OLGA has been recognized as a reference solution for transient multiphase flow analysis, enabling petroleum engineers to accurately simulate the simultaneous movement of oil, natural gas, water, condensate, and other fluids through wells, flowlines, pipelines, risers, subsea production systems, and complete production networks.
Unlike steady-state simulators, OLGA models how production systems behave over time, making it an essential engineering tool for evaluating operational changes, startup procedures, shutdown events, slugging, hydrate risks, pigging operations, pressure transients, and many other dynamic scenarios.
Whether your project involves an offshore deepwater field, an onshore gathering network, or a complex subsea development, OLGA 2026.2 provides sophisticated simulation capabilities that support engineering analysis throughout the lifecycle of oil and gas production systems.
