WHAT WE SOLVE
Gas compression problems rarely begin with the compressor alone.
Declining pressure, production bottlenecks, unreliable equipment and project risk are usually system-level problems. ETA Energy Solutions helps oil & gas operators understand the real constraint, evaluate the feasible options and define an independent route forward.
Start with the business and engineering problem—not the service name
You do not need to know whether you need a conceptual study, integrated model, debottlenecking exercise, CompressorDoc™ study or Owner's Engineer engagement before contacting ETA. Start with what is happening and what decision must be made.
Declining Reservoir or Wellhead Pressure
"What compression do we need, where should it go, and when should we install it?"
As reservoir and wellhead pressure decline, operators need to know when natural deliverability will become insufficient and what compression configuration will sustain production without creating unnecessary CAPEX or late-life operating problems.
- When should compression be introduced?
- Wellhead, nodal, hybrid or centralised compression?
- Where should compressor packages be located?
- How many trains are required?
- What suction-pressure range should they cover?
- How should configuration change as production declines?
- What production plateau or reserve recovery is achievable?
- What is the CAPEX / OPEX impact?
Production Bottlenecks & Capacity Constraints
"Do we really need more compression—or can we unlock capacity from what we already have?"
Production loss is not always caused by insufficient compressor capacity. Pressure losses in the gathering network, mismatched operating conditions, restrictive piping or the way existing equipment is configured may be the real constraint.
- Where are the network pressure losses?
- What is restricting flow?
- Can pipeline debottlenecking defer compression?
- Can existing compressors be reconfigured or reused?
- Would a rewheel recover useful operating range?
- Which modifications offer the best production return?
- What is the operating envelope after modification?
- What production gain justifies the CAPEX?
Unreliable, Inefficient or Ageing Compression
"Why is the compressor underperforming—and is it worth keeping it?"
Poor availability, rising maintenance cost, degraded efficiency and ageing equipment create difficult late-life decisions. The answer may be operational optimisation, repair, rewheel, rehabilitation, major modification or replacement.
- How does current performance compare with design?
- What is causing recurring reliability problems?
- Is the compressor operating efficiently?
- Is the equipment fit for continued service?
- What residual life remains?
- Should we rewheel, revamp or replace?
- Can maintenance and OPEX be reduced?
- What rehabilitation should be prioritised?
FEED, Procurement & Compression Project Risk
"How do we make sure the compressor package we buy is actually the package the field needs?"
Once a compression project moves into FEED, procurement and EPC, technical risk can increase quickly. Requirements may be diluted, interfaces overlooked and vendor proposals optimised around the package rather than the production system.
- Is the Basis of Design robust?
- Is the compressor scope of supply complete?
- Does the RFQ / ITB reflect actual operating requirements?
- Which vendor proposal is technically strongest?
- Are deviations being properly challenged?
- Does detailed design preserve concept intent?
- Are FAT / performance tests adequate?
- Will the package perform once installed on site?
"We have an answer—but can we trust it enough to act?"
Operators often already have an internal study, vendor recommendation or preliminary concept. The problem is not lack of analysis. It is whether the answer is robust enough to support management, procurement or investment approval.
- Independent validation of internal studies
- Independent review of vendor proposals
- Model validation and assumption challenge
- CAPEX / OPEX and cost-benefit comparison
- Business case and decision-support input
- Clear recommendation and route forward
The real deliverable is often confidence: an independently verified answer that the organisation can take forward.
ETA's independence matters most where management needs confidence that the recommended solution has been selected because it is technically and commercially right—not because a particular equipment supplier or contractor benefits from the decision.
From uncertainty to an implementable engineering decision
The exact engineering workflow varies by problem, but most engagements follow the same decision logic.
One problem may require more
than one engineering
