Steady-state and transient simulations of well and surface facilities
Tools for steady-state and transient simulations of well and surface facilities to identify and mitigate flow assurance challenges.
The Olga™ dynamic multiphase flow simulator models transient flow (time-dependent behaviors) to maximize production potential. Transient modeling is an essential component for feasibility studies and field development design. Dynamic simulation is essential in deep water 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 analysis 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 various types of process equipment, the Olga simulator provides an accurate prediction of key operational conditions involving transient flow.
The Olga simulator enables key flow simulation applications, including
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.

Previously, the plotting configuration for a case was discarded whenever the case was closed. Now, this configuration is saved within the case file, allowing plots to be automatically reloaded when the case is reopened. This enhancement applies to all types of 2D plots.
It is now possible to initialize profile and trend plots with an offset applied to the x-axis—length for profile plots and time for trend plots.
We’ve introduced powerful new functionality to the plotting tool that enables you to import and compare external data directly with OLGA simulation results.
The PVT package used for calculating inhibitor properties is specified using the INHIBITORPROPERTIES key under the OPTIONS section. In addition to the previously available options—Simple and Multiflash—two new PVT packages are now supported: Symmetry and PVTSim.
The Lennard-Jones viscosity model in Multiflash is now enabled for Olga compositional tracking simulations.
Previously, the level gradient term was not included in the steady-state pre-processor. Now, it is incorporated into the force balance calculations for oil and water layers within the steady-state pre-processor.
NExT offers a comprehensive training program to support users of the SLB software, plugins, and other software products.
