Olga compositional tracking

The Compositional Tracking module models dynamic changes in fluid composition and tracks individual components along the pipeline.

Overview

In Olga Three Phase, the chemical compositions are defined as constant throughout a simulation. With the addition of Olga Compositional Tracking, the user can accurately model changes in composition along the pipeline or well.

Merging fluids of different compositions require rigorous tracking.

Identify changing fluid properties and individual components along the pipeline.

Applications

Managing networks merging with varying fluids or multilateral wells with fluids with differing compositions

Simulating shut-in and start-up scenarios

Modeling gas injection and gas lift

Handling changes in composition at inlets and sources

Tracking gas quality

Analyzing blow-down scenarios

Evaluating safety processes

Artificial lift systems pipeline whole icon

Dense phase pipeline start-up and operation

Dead oil circulation

Benefits

The Olga Compositional Tracking module takes into account changes in flow due to slip effects (velocity differences between phases), interfacial mass transfer, as well as where networks merge with comingling of different fluids and changes in fluid composition at the inlet.

In the compositional model, mass equations are solved for each component in the gas phase, droplets, oil and water phases. Thus, the compositional model tracks the changes in composition in time and space, and ensures more accurate fluid description in complex compositional flow environments.

Compositional tracking is critical for blowdown and gas lift analysis, in which compositional effects are more significant.
