See how difficult compression decisions became practical engineering outcomes.
Explore how ETA Energy Solutions has helped operators select compression concepts, overcome declining pressure, improve reliability, validate difficult decisions and protect compression projects through procurement and execution.
Start with the challenge—not the project category
Filter by the engineering problem your team is facing. Each case summarises the client situation, the decision at stake, ETA's role and the resulting outcome.
Third Wellhead Compression Train
Pluspetrol · Camisea, Peru
From declining reservoir pressure to a technically controlled third compression train
Declining Cashiriari reservoir pressure created the need for additional compression. ETA supported the operator as Owner Engineer across package definition, procurement, technical evaluation and EPC assurance.
Compression Train Fitness-for-Purpose & Rewheel Study
Existing reliability problems and a planned satellite-field tie-in meant the main compression train required fundamental reassessment.
Independent Technical Assurance for Compressor Rewheel
The operator required independent protection of its technical requirements during OEM design, manufacture and FAT.
Integrated Asset Modelling & Compression Conceptual Design
Inaccurate integrated models and simulation runs taking about a week were blocking field-development decisions.
Compression Concept Selection for a Declining Gas Field
Declining reservoir pressure, remote infrastructure and multiphase-flow challenges made distributed wellhead compression difficult.
Rewheel Technical Assurance for Two Compression Trains
Declining reservoir pressure required two existing compressor trains to be rewheeled for changed operating conditions.
Sales Gas Turbocompressor Performance & Shaft Power Study
Lower-than-expected wellhead pressures required confirmation that rewheeled compressors could still meet production and commercial requirements.
Independent Downhole Compression Technology Review
Remote environmentally sensitive assets made distributed surface wellhead compression challenging.
Gas Storage Injection Capacity Enhancement Study
The operator wanted to maximise injection capacity in order to improve facility economics.
Life-of-Field Compression Concept for Declining Pressure
Declining reservoir pressure required a structured concept study covering technology, sizing and phased implementation.
Third Wellhead Compression Train — Owner's Engineering, Procurement & EPC Technical Assurance
The individual case-study pages should all use this same problem → decision → engineering → outcome structure.
The Client Situation
Declining reservoir pressure in the Cashiriari field created a requirement for additional compression to support future production and maintain sufficient pressure for fluids entering the central processing facility.
The Decision at Stake
The operator needed to procure and execute a third compression train while confirming that both the proposed package and existing compression philosophy remained technically suitable for future duty.
ETA's Role
ETA was engaged as Owner Engineer, providing specialist gas compression engineering and operator-side technical support.
Procurement Support
- Reviewed and validated compressor envelopes.
- Checked sparing and standby philosophy for existing and proposed trains.
- Prepared the turbo-compressor RFQ package.
- Managed pre-bid and post-bid technical clarifications.
- Completed technical evaluation of compressor bids.
- Supported contract award recommendation.
EPC Technical Assurance
- Reviewed detailed-design documents, datasheets and drawings.
- Participated in compressor-facility HAZOP activities.
- Provided manufacturing inspection and technical supervision.
- Witnessed Factory Acceptance Tests for gas turbine and compressor bundles.
- Supported field performance testing and commissioning.
The Outcome
The operator retained independent specialist technical oversight from procurement into EPC execution, helping preserve compressor-system requirements through vendor selection, detailed design, manufacture and testing.
