OLGA

Multiphase Flow Simulator

OLGA is the market-leading simulator for engineering the flow of oil, water and gas in wells, pipelines and receiving facilities.

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.

Successful design and operation of multiphase production systems rely on detailed understanding of flow behavior. OLGA provides solutions through accurate modeling of true dynamics.

OLGA has an extensive package of standard and specialized modules developed through extensive research and field measurements, which are capable of simulating demanding challenges in multiphase transport.

OLGA can also be used in eField Production and as run-time in integrated simulators.

Flow Assurance

OLGA is used in feasibility studies, conceptual studies, FEED and detailed designs and is essential for defining operating procedures and control schemes.

Application examples:

• Transient thermohydraulics during start-up/shut-in
• Optimal design for maximum operating envelope
• Process and control system design
• Flow assurance, investigating hydrates, wax, asphaltenes, corrosion, emulsions, scale and sand
• Liquid inventory during pigging and rate changes
• Slug mitigation and control

Fluid systems that can be modeled:

• Oil and natural gas flowlines
• Wet gas and condensate flowlines
• Wellstream fluids
• Dense phase flowlines
• Single phase gas or liquid flowlines
• Laboratory experiments

Full network capability

OLGA has full network capability, allowing for definition of converging and diverging transport and process networks as well as closed loops. This flexibility enables the engineers to simulate a set of applications such as well and pipeline networks, gas lift and complete process systems.
