Pipesim
steady-state multiphase flow simulator
Overcome fluid flow challenges and optimize production.
Olga core system
Olga core system is the main module for the Olga simulator. It includes the steady-state and transient network solvers for three phase flow—water, oil and gas. The solvers calculate the slip (velocity difference) between the phases.
Overview
In most cases, production tubulars and pipelines have three phases flowing simultaneously. At low velocities there is considerable slip between gas and liquids, and also between oil and water. As a result, liquids tend to collect in low spots along the system, which leads to high local accumulations and increases the potential for slugging and surges. Where water accumulates, there is also potential for serious corrosion problems and hydrate formation.

Applications
The Olga simulator supports process equipment modeling in deepwater field developments and other complex developments, and accurately models dynamic multiphase flow. Oil and water dispersions are also predicted; dispersion viscosities—which may deviate considerably from the oil-water average viscosities—are calculated by the default models or user-defined tuning factors.
Benefits
Models three-phase flow—oil, water and gas
Predicts dispersion of oil and water
Features
- Enables fundamental process equipment modeling
