G/L Separation And Liquid Boosting

Main Drivers:

Low pressure reservoirs

Decreasing reservoir pressure

Heavy Oil

Depressurization necessary due to hydrate formation

Stabilize production, i.e damp slug flow

Reduce power consumption by single phase boosting

Gas Compression

Main Drivers:

Decreasing reservoir pressure Maintain gas velocity to avoid liquid accumulation in flowlines

Reduce need for water injection or pressure support

Avoid surface installations:

Subsea to beach

Long step-outs possible
