Rewheel Technical Assurance 2

Written By Sodi Toby

Client: Pluspetrol Peru Corporation

  • Field (Type): Camisea (Gas & Condensate production; Onshore Peru)

  • Objectives: 

    • The client wanted to rebundle two centrifugal compressors as part of the ongoing development of the asset to meet current duties (lower wellhead pressures)

    • The newly rebundled compression trains would move from 2 X 100% operation to 2 x 50% with load sharing

    • The client wanted a better understanding of the minimum pressure capabilities of the new compressor bundles.

    • The client wanted technical assurance support relating to the ability of the new compressor rewheels to meet specific suction pressure and mass flow requirements

    • The client also desired to establish the maximum flow capabilities of the new compressor bundles at a range of suction pressures

  • Challenge: The key driver for the rewheeling of two compression trains was the declining pressures of the Pagoreni reservoirs.

  • Our Engagement:  Eta was engaged as Engineering Consultants because of its unique gas compression expertise and understanding of the client’s asset portfolio.

  • Approach: compressor performance analysis, modelling, and simulation

  • Stake:  Inability to fully ascertain the maximum flow capacity of the revamped compressors at a variety of arrival pressures

  • Results:

    • The minimum suction pressure capabilities of the new compressor bundles based on expected in-service performance were successfully demonstrated for the benefit of the client

    • The maximum flow capacity of the new compressor rewheels for a range of duties was successfully demonstrated for the benefit of the client
