Olga dynamic multiphase flow simulator
The industry-standard tool for dynamic multiphase flow simulation
Overview
The Olga™ dynamic multiphase flow simulator models transient flow (time-dependent behaviors) to maximize production potential. Transient modeling is an essential component for feasibility studies and field development design. Dynamic simulation is essential in deep water and is used extensively in both offshore and onshore developments to investigate transient behavior in pipelines and wellbores. Transient simulation with the Olga simulator provides an added dimension to steady-state analysis by predicting system dynamics, such as time-varying changes in flow rates, fluid compositions, temperature, solids deposition, and operational changes.
From wellbore dynamics for any well completion to pipeline systems with various types of process equipment, the Olga simulator provides an accurate prediction of key operational conditions involving transient flow.
Applications
The Olga simulator enables key flow simulation applications, including
- liquids handling
- sizing separators and slug catchers
- managing solids
- simulating key operational procedures including start-up, shut-down, and pigging
- modeling for contingency planning
- assessing environmental risk in complex deepwater drilling environments.
Benefits
Maximize production and minimize risk
Successful production system design and operations requires a detailed understanding of multiphase flow behavior. Flow modeling and simulation provides valuable insights into flow behavior, including the physics describing flow through the entire production systems, from reservoir pore to process facility.
