Life Cycle Simulation

Dynamic modeling provides key design requirements and is essential for maximizing the production window.

Assuring stable production(flow assurance) throughout the field life is the main focus for detailed analysis with OLGA.

Successful design and operation of onshore and offshore multiphase production systems rely on the understanding of flow behavior to ensure technical, operational and HSE integrity.

OLGA is used from the engineering of systems through to the operation, resulting in overall capital and operating cost effectiveness.

Efficient production involves the multiphase transport of oil, gas and water from the reservoir, through wells and pipelines, to the processing installations. OLGA models the flow of production using complex simulations which predict the behavior of the fluid flow.

The unique competitive advantage of OLGA lies in the ability to model the dynamic qualities of production for all multiphase scenarios.
