Schlumberger OLGA 2025 is a dynamic multiphase flow simulator used for modeling transient flow behaviors in oil and gas production systems to maximize production potential. It’s widely applied in feasibility studies, field development design, and operational scenarios for both offshore and onshore pipeline networks. The software simulates time-dependent behaviors like flow rates, fluid compositions, temperature changes, solids deposition, and operational procedures (e.g., start-up, shut-down, pigging). It also supports advanced applications such as sizing separators, managing solids, contingency planning, and assessing environmental risks in deepwater drilling.
Key Features of Schlumberger OLGA 2025.2:
CO2 Handling for CCS: Features a new solver developed through the OLGA CO2 Joint Industry Project (JIP), enhancing CO2 transport and injection simulations for carbon capture and storage (CCS) systems. It offers improved numerical stability, robust vaporization/condensation modeling, and optimized capital/operational costs.
Pipeline Network Modeling: Simulates complex pipeline systems with equipment like compressors, valves, heat exchangers, and pumps, accounting for heat transfer, pipe branching, and corrosion.
Dynamic and Steady-State Analysis: Provides transient flow simulations for greater precision compared to steady-state simulators like PIPESIM, handling complex fluid interactions (e.g., bubbling, slugging).
Limitations: Struggles with simulations of extra heavy and heavy oil due to inaccuracies in the black oil model for low API values.
