Flow Assurance & Multiphase Flow Modeling
An analysis of the flow composition and the expected conditions along the pipeline is used to determine locations that are prone to liquid drop-out.
Analysis of a pipeline and the inhibited fluid composition is used to verify the operating conditions that will be free from hydrates.
Slugging analysis of a trunkline during a production ramp-up and its effect on the separation capacity of the Gas Processing and Dehydration Facility.
Slugging statistical analysis of a trunkline for different production phases.
Multiphase modeling of a pipeline system helps to improve the reliability of the system by identifying critical conditions to be avoided. It is used to evaluate flow assurance issues such as:
- Hydrate formation
- Liquid accumulation / corrosion
- Wax deposition
- System control and production management
These issues are of particular concern for pipelines with limited capacity, bottlenecks, and those that experience harsh transient conditions. Multiphase flow modeling can be applied to a variety of pipeline and production systems including compression and pumping stations as well as offshore pipeline networks.
Multiphase modeling can also be used to prevent slugging and liquid drop-out complications in gas pipelines by:
- Identifying critical gas liquid/velocities and gas oil ratio of the streams to be transported
- Identifying phase change conditions
- Determining operating conditions to avoid
- Predict locations prone to liquid drop-out and thus corrosion/liquid accumulation
Field troubleshooting and benchmarking services can also be provided to complement the modeling.
