Gas Compression Strategy & Concept Selection
Determine what compression you need, where you need it and when you need it before committing CAPEX.
ETA Energy Solutions helps oil & gas operators develop technically and commercially defensible life-of-field gas compression strategies by integrating production forecasts, declining pressure, gathering-network behaviour and compressor performance.
✓ Independent of OEMs ✓ Integrated system analysis ✓CAPEX & OPEX considered ✓ Life-of-field approachDeclining pressure changes the compression decision throughout field life.
A compressor selected only for today's operating point may become oversized, inefficient or operationally constrained as production and suction pressure decline.
The real question is which development strategy gives the best balance of production recovery, reliability, flexibility and cost throughout the economic life of the field.
Questions the study can answer
- How long can production be sustained without compression?
- Should pipeline debottlenecking come first?
- Where should compression be installed?
- What suction-pressure range should packages cover?
- How many units or trains are required?
- How should the configuration evolve as production declines?
- Which driver technology is most appropriate?
- What is the production and economic benefit?

Select the solution because it is right for the field.
ETA has no commercial interest in selling a particular compressor, driver or EPC solution.
The outcome is not simply a compressor recommendation. It is a life-of-field strategy showing what to install, where, when and why.
