Independent engineering for difficult gas compression decisions.
ETA Energy Solutions is a specialist engineering consultancy helping oil & gas operators make better decisions about compression strategy, production optimisation, compressor reliability and major compression projects.
We combine deep gas compression expertise with integrated production-system thinking—and remain independent of compressor manufacturers and EPC contractors so our recommendations can be driven by the operator's interests.
Specialist expertise for decisions that are too important to get approximately right.
ETA was built around a simple observation: gas compression decisions often sit between several disciplines.
A compressor package may be technically excellent and still be the wrong solution if its location, operating envelope, timing or relationship with the wider production system has not been properly understood.
Likewise, an operating compressor problem may appear to be a machine problem when the real cause sits elsewhere in the process system.
ETA was established to provide operators with the specialist compression depth and system-level engineering needed to make those decisions independently.
Our founding principle: independence.
ETA has no ownership links to compressor OEMs and no commercial affiliation with EPC contractors.
We are deliberately not a generalist engineering consultancy.
ETA focuses on the compression decisions where specialist rotating-equipment knowledge must be connected with the wider production system and project.
Compression Strategy & Concept Selection
Determine what compression a field requires, where it should be located and when it should be introduced.
Production Debottlenecking & System Redesign
Find hydraulic and equipment constraints and define modifications that unlock production.
Compressor Performance & Reliability
Diagnose underperformance and determine the right optimisation or life-extension strategy.
Owner's Engineering & Technical Assurance
Protect the operator through FEED, procurement, EPC, testing and commissioning.
The principles behind every engagement
These principles are more useful to a prospective client when they explain what ETA's way of working means for the project.
True Independence
No OEM ownership or EPC affiliation means technology, modification and vendor recommendations can be based on operator value rather than equipment sales.
Specialist Engineering Depth
ETA concentrates on gas compression, rotating equipment, production-system interactions and the engineering interfaces that determine whether compression performs as intended.
System-Level Thinking
We consider reservoir pressure, wells, gathering networks, compressor performance, auxiliaries and project constraints where they affect the decision.
Decision-Focused Outcomes
Engagements are structured around what the operator must decide or achieve rather than producing analysis for its own sake.
Client-Side Thinking
When acting as Owner Engineer, ETA works from the operator's perspective: production, risk, schedule, budget and technical integrity.
Quality by Design
Engineering decisions are supported by structured processes, documented reasoning and a certified quality-management system.
Professional competence backed by recognised standards
Senior engineers with focused experience
Sodi Toby, CEng FIMechE
Sodi leads ETA's technical and management direction, with specialist experience in gas compression, rotating equipment, integrated asset modelling, front-end studies and field-development strategy.
His work has included major international oil & gas projects and technical leadership across the compression lifecycle.
Michael Drage, CEng MIChemE
Michael brings more than three decades of process and project engineering experience, with particular strength in front-end conceptual design, FEED management, PMC and operations support.
His broader process background strengthens ETA's ability to connect compressor design with process-system and project requirements.
Build the project team around the problem—not around a fixed bench.
ETA operates with a core senior team supported by a curated network of specialist associates.
This model allows the consultancy to bring in the particular technical depth required by an engagement rather than assigning generalist resources simply because they are available.
The client retains a clear ETA technical lead while specialist disciplines are added where the work genuinely requires them.
Meet Our Consultants & Associates →Confidence should come from more than marketing claims.
Professional credentials and affiliations support the technical authority behind ETA's work, while ISO 9001 provides an independent framework for quality-management discipline.
Certified quality-management system supporting disciplined engineering processes and documented decisions.
Senior engineering leadership holds professional Chartered Engineer credentials.
Team affiliations include IMechE, IChemE, SPE and GPA Europe.
The purpose of professional standing is not to decorate a website. It is to give clients confidence in the judgement behind important engineering decisions.
Keep affiliations visible, but always explain what they mean for the buyer: professional competence, ethical responsibility, technical development and quality discipline.
