• Developed through HORIZON JIP
  • Runs at the same speed as the standard OLGA stratified flow model
  • Includes improved stratified flow model


OLGA High Definition provides accurate simulation for stratified flow in gas/condensate lines where holdup predictions are critical.

The OLGA High Definition model for three phase stratified pipe flow is formulated as a simplified 3D model using preintegration and innovative mathematical manipulations. It has been adapted to the 1D and transient numerical scheme in the OLGA simulator—providing substantial accuracy improvements simulating stratified flow, while maintaining standard OLGA calculation speeds. 

Typical cases

  • Liquid holdup and pressure drop predictions for stratified flow in gas condensate systems
