Fifteen projects. Four continents. Measurable results every time.

Existing reliability issues and a planned satellite field tie-in required a fundamental reassessment of the main compression train, including full rewheel specification and technical assurance.

Following the rewheel study, Eta provided Owner Engineer technical assurance throughout the design, manufacture, and FAT stages to protect BP's interests with the OEM.

Persistent reliability issues and concerns about the system's suitability for future operational demands required independent assessment and an actionable improvement roadmap.

Declining Cashiriari reservoir pressures required a third compression train in a remote, biodiversity-sensitive environment with significant multiphase flow challenges. Eta acted as Owner Engineer throughout EPC execution.

Project management consultancy and technical assurance support for compression project at the Cashiriari field, covering procurement, vendor management, and commissioning support.

Lower than expected wellhead pressures required assessment of reheeled compressors' capability to meet production targets. Third-party commercial relationships depended on accurate shaft power calculations.

Declining Pagoreni reservoir pressures required rewheeling of two compression trains. Eta provided independent technical assurance across both trains from design through to FAT.

Inaccurate integrated asset models taking one week per simulation run were blocking field development decisions. Eta rebuilt the model and delivered a validated conceptual design for optimal field development.

Fields in a remote, biodiversity-sensitive Amazon location required a compression strategy that avoided distributed wellhead installations. Multiphase gas and condensate flow presented additional flow assurance complexity.

A client operating in areas of significant biodiversity needed an independent assessment of downhole compression technology as an alternative to surface wellhead compression — including technical maturity, cost, and risk evaluation.

The driver was maximising the injection capacity of the storage facility to improve project economics. Eta assessed technical options and defined a viable enhancement concept with cost and schedule estimates.

Assessment of options to increase the injection and storage capacity of the Hatfield West facility, with the objective of improving overall project economics and commercial flexibility.

Declining reservoir pressures required a rigorous conceptual study to define the optimal compression strategy, covering technology selection, sizing, and phased implementation planning.
