Five specialist tools. Oneclearer route throughdifficult compressiondecisions.
Gas compression decisions change as a project moves from early uncertainty to concept selection, modification, procurement and operation. ETA's proprietary decision tools provide a structured engineering method for the specific decision at each stage.
The methodology
should fit the decision
—not the other way around.
A field-development question is fundamentally different from an equipment-reliability problem. A production bottleneck requires a different engineering sequence from an EPC technical assurance assignment.
ETA's decision tools make that distinction explicit. Each tool is designed around a particular class of compression decision, with defined stages and a practical end-state.
The tools are designed to prevent:
- Solving the wrong engineering problem.
- Selecting a compression concept too early.
- Treating symptoms instead of root causes.
- Replacing facilities that could be cost-effectively modified.
- Losing design intent through procurement and EPC.
- Producing technically good studies that do not support a decision.
Start with the decision that needs
protecting
Define the right question before committing engineering effort.
Use when the objectives, scope, constraints, stakeholders or definition of success are unclear.
"Do we actually agree on what decision this study needs to answer?"
It protects against
Poorly framed studies, misaligned stakeholders, unnecessary engineering effort and technically correct outputs that fail to answer the business question.
Typical outcome
A clear decision statement, objectives, constraints, interfaces, success criteria and fit-for-purpose engineering scope.
Select the optimum life-of-field compression concept.
Use when declining pressure or field development requires a decision on compression location, timing, capacity and configuration.
"What compression should we install, where, when and why?"
It protects against
Selecting a concept that is over-specified, under-specified or poorly matched to changing life-of-field production conditions.
Typical outcome
A technically and commercially defensible compression concept and development roadmap.
Unlock capacity from existing gas compression facilities.
Use when production is constrained but the lowest-cost answer may be targeted modification rather than complete replacement.
"Can we achieve the production objective by modifying what we already own?"
It protects against
Committing unnecessary replacement CAPEX before identifying network, compressor or operating modifications that could release capacity.
Typical outcome
A quantified system redesign showing the bottleneck, preferred modification and implementation basis.
Find the root cause before another intervention.
Use when an existing compression system has chronic reliability, performance, efficiency or maintenance problems.
"Why does this problem keep returning?"
It protects against
Spending on repeated repairs or modifications that address symptoms while the underlying technical cause remains unresolved.
Typical outcome
A documented compressor-system health assessment, root-cause findings and prioritised uptime roadmap.
Protect operator requirements from FEED through commissioning.
Use when a compression concept is moving into specification, procurement, vendor design, manufacture, testing or site execution.
"Is the project actually delivering the compression solution we approved?"
It protects against
Technical intent being diluted by specifications, contractor interfaces, vendor exceptions or design decisions during FEED and EPC.
Typical outcome
Independent technical assurance from design definition through procurement, manufacture, testing and commissioning.
Match the methodology to the
decision
| Tool | Use it when... | Decision it protects | Main outcome |
|---|---|---|---|
| Extraclarity™ | Objectives or scope are unclear | Starting the wrong study or solving the wrong problem | Clear scope and decision criteria |
| CONCEPTCOMPRESSOR™ | Selecting future compression | Making an expensive, difficult-to-reverse concept choice | Compression concept and development roadmap |
| modgas™ | Existing facilities are constrained | Spending on unnecessary full replacement | Implementable debottlenecking / redesign |
| CompressorDoc™ | Existing compression is unreliable or underperforming | Repeatedly treating symptoms instead of causes | Root-cause findings and uptime roadmap |
| verify™ | A project is in FEED, procurement or EPC | Losing technical intent during delivery | Independent technical assurance |
The service tells you
what ETA does. The
decision tool tells you
how ETA structures
the decision.
Separating these two ideas makes ETA easier for a new prospect to understand while preserving the value of the proprietary methodologies.
Example
Service: Gas Compression Strategy, Concept Selection & Integrated Asset Modelling.
Decision Tool: CONCEPTCOMPRESSOR™.
The service describes the engineering capability. CONCEPTCOMPRESSOR™ describes the structured method ETA uses to arrive at la decision.
Not sure which tool fits the
decision on your desk?
Start with the engineering or business decision rather than choosing a methodology yourself. We'll identify whether one of these tools is appropriate—and say so if it isn't.
