Gain deeper insight into flow behavior to 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.
The OLGA dynamic multiphase flow simulator models time-dependent behaviors, or transient flow, to maximize production potential. Transient modeling is an essential component for feasibility studies and field development design. Dynamic simulation is essential in deepwater 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 analyses 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 all types of process equipment, the OLGA simulator provides an accurate prediction of key operational conditions involving transient flow.
Key flow simulation applications
The OLGA simulator enables key flow simulation applications, including
- liquids handling
- sizing separators and slug catchers
- managing solids (e.g., hydrates and wax)
- simulating key operational procedures including start-up, shut-down, and pigging
- modeling for contingency planning (kill mud density and kill flow rates for blowout control)
- assessing environmental risk in complex deep water drilling environments.
From early conceptual and planning phases to full field production operations and contingency planning, the OLGA simulator helps you to determine the best design, operational procedures, optimization, and risk mitigation strategy.
30 years of development—supported by over 200 experts
Customer-supported innovation and research has been at the core of the OLGA simulator’s development for more than 30 years. Through testing and verification since the 1980s, the OLGA simulator has become the de facto industry standard for modeling flow dynamics. Validation of the OLGA code with large-scale lab research and the largest database of actual production data from leading E&P companies are key factors in its ongoing development.
Major oil and engineering companies participate in the OLGA Verification and Improvement Project (OVIP). The program is now in its seventh 3-year cycle and has collected the world’s largest database of lab and field data. This data has been used to validate and adapt the multiphase flow models. Results are continuously implemented in the OLGA simulator, improving the core technology to better match the realities of operations.
Additionally, the Horizon project is cosponsored by seven major oil companies. This project addresses problems related to the cost-effective development and safe operation of long-distance gas-condensate transport and long-distance transport of oil well streams.
