When compression decisions affect production, specialist engineering matters.
ETA is an independent engineering consultancy focused on optimal gas compression — helping operators make better decisions about compression design, asset optimisation, reliability and major projects.
We bring together gas compression, rotating equipment and integrated asset expertise to solve the problems that are hardest to resolve with generalist engineering alone.
Compression problems rarely stay inside the compressor.
A machine can be performing exactly as designed and still fail to deliver what the production system needs.
ETA exists at that intersection — connecting compressor expertise with the wider production, process and project decisions that determine the outcome.
Declining field pressure
Determine when compression is required, where it belongs and what configuration makes sense as the field changes.
Constrained production
Identify the real system constraint and determine whether compression, modification or operating changes can unlock capacity.
Unreliable compression
Separate compressor problems from wider system causes and define the intervention that addresses the actual issue.
High-stakes projects
Give the operator independent technical assurance from concept and FEED through procurement, execution and commissioning.
Specialist capability across the compression lifecycle.
ETA is deliberately focused. We do not try to be everything to everyone. Our expertise sits where gas compression, rotating equipment, production systems and project decisions meet.
Compression Strategy & Concept Selection
Determine what compression a field requires, where it should be installed and when it should be introduced.

Explore our servicesProject Management Consultancy
Add specialist engineering depth to projects where compression decisions have significant technical, schedule or delivery consequences.
Explore our servicesOur recommendation does not need to lead to an equipment sale.
ETA has no ownership links to OEM manufacturers and no commercial affiliations with EPC contractors.
That gives clients an engineering partner who can evaluate technologies, vendors, modifications and project assumptions without having a commercial interest in the answer.
We can recommend optimisation when an existing system can deliver the required result.
Technical recommendations can be assessed on performance and operator value rather than equipment sales.
We can question design decisions while staying focused on the operator's requirements.
Engineering, production and economic merit remain the basis for the recommendation.
From difficult question to defensible engineering decision.
Our work is structured around the decision the client needs to make — not around producing analysis for its own sake.
Understand
Define the production, technical and commercial problem.
Diagnose
Establish what is actually limiting performance.
Evaluate
Compare credible technical options independently.
Define
Turn the preferred option into a practical project basis.
Assure
Protect the operator through delivery and execution.
Six principles that shape every engagement.
True Independence
No OEM ownership or EPC affiliation. Recommendations are based on engineering merit and client value.
Engineering Depth
Specialist expertise at the intersection of gas compression, rotating equipment and process engineering.
Measurable Outcomes
Engagements are scoped around specific operational or commercial outcomes rather than reports for their own sake.
Client-Side Thinking
When acting as Owner Engineer, we think from the operator's perspective: production, risk, schedule and budget.
Transparent Communication
We communicate difficult findings, risks and uncertainties clearly so clients can make informed decisions.
Quality by Design
ISO 9001 supports rigorous processes, documented reasoning and auditable engineering decisions.
Senior engineers with decades of focused experience.
Clients are not buying a generic consultancy team. They are buying specialist judgement from engineers who understand the environments in which compression decisions are made.
