Successful design and operation of multiphase production systems rely on detailed understanding of flow behaviour. OLGA provides solutions through accurate modelling of true dynamics.
Pipeline flow assurance and well dynamics with OLGA ensure technical, operational and HSE integrity during design and operation of production systems throughout the entire life cycle. This results in capital and operating cost effectiveness. Similarly, OLGA is successfully deployed in e-field production systems and available in a run-time version for integrated simulators
OLGA is structured with a modular solution to yield the ability to identify, prevent and solve flow assurance problems throughout the field life. Our team will assist in configuring the appropriate combination.
The OLGA 7 graphical interface provides a wide range of tools, workflows and workspaces to perform your studies. The interface also offers powerful analysis tools to visualise, export, ultimately understand, and communicate the dynamics of the simulated model.
OLGA has through the years proven significant value for long term well performance both in the planning and operational phases.
Understanding the impact of complex flow regimes in wells is crucial for production optimization.
Dynamic simulations identify instabilities and flow problems, giving a better understanding of the overall long-term well performance and total recovery.

Online solutions based on OLGA have proven valuable in more than 30 comprehensive installations world-wide since 2005.
OLGA models developed during design phases are used as a basis for production management systems later in the project life cycle, and are tuned online once operations commence, yielding a “transparent pipeline” for the operators.

Successful design and operation of onshore and offshore multiphase production systems rely on the understanding of flow behaviour 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 behaviour 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.
