Pipeline Flow Assurance

Solutions

OLGA is the world leading multiphase flow simulator and an industry standard within the area of flow assurance. Through continued development since 1980, OLGA has proven its accuracy in both the transient and the steady-state simulations of multiphase production and transportation.

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

Our pipeline flow assurance solutions 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.

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 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
Pipeline blockers as hydrate and wax
Liquid inventory during pigging and rate changes
Slug mitigation and control

Fluid systems that can be modelled:

Oil and natural gas flowlines
Wet gas and condensate flowlines
Wellstream fluids
Dense phase flowlines
Single phase gas or liquid flowlines
Multi component or single component fluids

Design purposes:

Pipeline sizes
Thermal insulation
Hydrate/Inhibitor
Liquid management/Pigging
Slug mitigation
Process capacity (integrated simulation)

Operational purposes:

Decision support
Procedure improvements
Adhoc operations
Modifications
Redesigns

OLGA is a truly versatile tool that solves a wide specter of flow assurance challenges.

The unique competitive advantage lies in the ability to model steady state and dynamic qualities of production for all multiphase scenarios in various network configurations.
