Gas compressionengineering services for thedecisions that determineproduction and projectvalue.
When reservoir pressure declines, a gathering network restricts production, an ageing compressor becomes unreliable or a project reaches FEED and procurement, the difficult question is rarely simply "Which compressor?"
ETA Energy Solutions helps oil & gas operators determine what compression is required, where it should be installed, when it should be introduced, how existing assets can be optimised and how the investment can be technically and commercially justified.
We don't start with a compressor. We start with the production decision.
Compressor vendors are excellent at designing and supplying compressor packages. But the operator's decision is broader: what does the field, production system and project actually need?
ETA combines compression engineering, process-system analysis, integrated modelling and project assurance to assess the complete decision rather than a single item of equipment.
Engineering advice aligned with the operator.
ETA is independent of compressor OEMs and EPC contractors.
- Independently challenge internal studies and vendor proposals.
- Compare optimisation, modification and new CAPEX.
- Consider production, reliability and economics together.
- Produce recommendations management and procurement can act on.
What we do
Four specialist services across the compression lifecycle
Each service can stand alone or form part of one continuous engagement—from early production and compression strategy through FEED, procurement, commissioning and optimisation of the operating asset.
Gas Compression Strategy, Concept Selection & Integrated Asset Modelling
CONCEPTCOMPRESSOR™ + Extraclarity™For field-development and late-life decisions where declining pressure means the compression requirement, location and timing must be defined before committing CAPEX.
Determine the optimum compression strategy before committing to equipment.
Evaluate production forecasts, declining pressure, gathering-system constraints and feasible compression schemes to determine the optimum location, timing, sizing, configuration and driver philosophy.
- Gas compression conceptual studies
- Wellhead and nodal compression
- Integrated asset modelling
- Production forecast sensitivities
- Compressor package sizing
- Compressor location studies
- Driver selection
- Life-of-field operating philosophy
- Compression phasing
- CAPEX / OPEX comparison
Production Debottlenecking & Compression System Redesign
modgas™For operating fields where pressure losses, changing production conditions or existing facility constraints are limiting deliverability.
Find the real production constraint before adding more equipment.
Analyse the production network and compression system together to determine whether the lowest-risk answer is pipeline debottlenecking, operational change, compressor modification, rewheel, reconfiguration or additional compression.
- Production network debottlenecking
- Pipeline hydraulic analysis
- Network model validation
- Pressure-drop analysis
- Operating-envelope development
- Compressor rewheel evaluation
- System reconfiguration
- Major modification studies
- Production benefit assessment
- Cost-benefit comparison
Compressor Performance, Reliability, Integrity & Life Extension
CompressorDoc™For compressors that are underperforming, unreliable, ageing or becoming increasingly expensive to maintain.
Understand why the system is underperforming—and what will restore reliable, economic operation.
Combine compressor design knowledge, operating data, process-system understanding and reliability analysis to separate symptoms from underlying causes.
- Compressor performance analysis
- Performance benchmarking
- Root-cause analysis
- Reliability investigations
- Fitness-for-service studies
- Residual-life assessment
- Rewheel studies
- Revamp / replacement comparison
- Maintenance optimisation
- Life-extension planning
Owner's Engineering, FEED/EPC Technical Assurance & Procurement Support
verify™For operator teams requiring specialist compression support from package definition and tendering through testing and commissioning.
Protect the operator's technical and commercial interests from specification through commissioning.
ETA provides specialist operator-side technical challenge and continuity as a compression project moves through FEED, procurement and EPC execution.
- Owner Engineer / Client Engineer
- Pre-FEED and FEED support
- Basis of Design
- Compressor package specifications
- RFQ / ITB preparation
- Supplier clarifications
- Technical bid evaluation
- Award recommendation
- Vendor design review
- Testing and commissioning support
Specialist capabilities used wherever the decision requires them
Integrated Asset Modelling
Integrate reservoir, wells, gathering network and compression performance to evaluate production forecasts and future compression requirements.
Surface Network & Pipeline Hydraulics
Validate network models, identify pressure losses and determine whether debottlenecking can unlock production or defer compression.
Compression Business Cases
Connect technical options with CAPEX, OPEX, production impact, cost-benefit analysis and investment decision requirements
Give management an answer it can approve—and procurement a solution it can act on.
Good engineering is not enough if the option cannot be defended commercially. Where required, our studies connect compressor and production-system performance to the information needed for management, FID and procurement decisions.
We don't just recommend a compressor.
We determine what the field and production system actually need, compare the technically feasible routes, quantify the implications, and develop a recommendation that can move from engineering discussion to investment and procurement.
