Special Studies for Turbocompressors – Study 1

27 May

Client: Pluspetrol Peru Corporation

Field (Type): Camisea (Gas & Condensate production; Onshore Peru)
Objectives:
- The client had recently implemented a re-bundle of their operating compression trains with a different (lower suction pressure) design and wanted to establish their operating envelope for the new bundles.
- To provide technical assurance support relating to investigating the ability of newly re-bundled compressors to meet lower suction pressure requirements.
- To forecast maximum flow capabilities of the newly re-bundled compressors at a variety of suction pressures
- To estimate the minimum suction pressures achievable by the newly re-wheeled compressors
- To provide quality assurance for client process model used for low suction pressure operation simulations
Challenge: Lower than expected process gas wellhead pressures, meant that technical assurance was needed to establish the extent to which the newly re-wheeled compressors could meet this demand while meeting production targets.
Our Engagement: Eta was engaged as Owner Engineer (Engineering Consultants) because of its unique gas compression expertise and understanding of the client’s asset portfolio.
Approach: operational performance benchmarking and deliverability analyses
Stake: It was commercially critical that production targets could continue to be met safely despite the lower wellhead pressures.
Results:
- Successfully established the operating range/envelope for safe low suction pressure operations
- Successfully benchmarked the capacity of the re-bundled compression trains for this low-pressure regime
- Successfully identified the risks of low suction pressure operation and recommended actions to manage them.

Sodi serves as our Managing Director and Projects Director. He has management and technical oversight across our offices. He graduated from the University of Sussex, UK with a first class MSc in Turbomachinery. Sodi has a track record of successfully managing production optimization and field development studies for major oil and gas companies internationally. He is an expert in gas compression and integrated asset modelling with more than a decade experience. In his career, the value he has provided in these areas has led to significant decisions which have provided immense production and project benefits for several operating companies. He has previously held senior roles including Head of Projects and Management Team Leader in a reputable engineering consulting firm from which he left to start up Eta Energy Solutions. He has also in previous roles, led software development teams in developing bespoke integrated asset modelling software. Sodi is a Chartered Engineer, professionally recognized by the Engineering Council (UK) and the Council for the Regulation of Engineering in Nigeria (COREN). He is also a professionally recognised member of the Institution of Mechanical Engineers (UK) and the Society of Petroleum Engineers (SPE).
