Make the right compression decision before declining pressure, bottlenecks or unreliable equipment cost you production.
ETA Energy Solutions helps oil & gas operators sustain production, unlock constrained capacity, improve compressor reliability and take defensible compression projects from concept through FEED, procurement and commissioning.
Four compression decisions that determine production and project value
Declining reservoir or wellhead pressure
What compression do we need, where should it be installed and when should it come online?
Production or network bottlenecks
Can we recover more production from the infrastructure we already have before committing new CAPEX?
Unreliable or ageing compression
Why is the system underperforming— and should we optimise, rewheel, rehabilitate or replace?
FEED, procurement or execution risk
Is the compressor package correctly specified, independently evaluated and technically assured?
We don't start with a compressor. We start with the production decision.
Compressor vendors are exceptionally good at designing and supplying compressor packages. But the operator's question is broader: what does the field, production system and project actually need?
ETA combines gas compression expertise with process engineering, production-system modelling and project assurance to evaluate the complete decision—from reservoir and gathering network behaviour through compressor performance, CAPEX, OPEX and execution.
The result is an independent recommendation aligned with production, reliability and investment objectives rather than equipment sales.
Engineering answers you can take to management, procurement and operations.
Our work is structured to move beyond analysis and produce a practical route forward.
- Independently verify internal studies and vendor proposals.
- Compare operational changes, modifications and new CAPEX.
- Translate technical options into production and economic consequences.
- Define a solution procurement can buy and operations can run.

From Technical Study to Decision
A technically correct answer is only useful
if your organisation
can act on it.
Where required, ETA connects engineering analysis to the commercial and project information needed to make investment, procurement and operating decisions.
We don't just recommend a compressor. We determine what
the field and production system
actually need.
Then we turn that answer into a solution that management can approve, procurement can buy and operations can run.

Why Clients Engage ETA
Specialist enough to go deep.
Independent enough to challenge.
Compression specialists
Focused expertise in centrifugal
compressors, gas compression systems,
process interactions and production
facilities.
Operator-aligned
No OEM or EPC affiliation means
recommendations can be based on the
operator's production, reliability and
economic interests.
System-level thinking
Compressor behaviour is assessed
together with reservoir pressure, wells,
gathering network, drivers, auxiliaries
and project interfaces.
Decision-focused
Studies are structured around the
decision the client must make, not
around producing analysis for its own
sake.

In gas compression, troubleshooting often

Development
In oil and gas field development, the
