Cardona-Pompano Concept Development Study - Xodus Group
Client: Stone Energy
Location: Gulf of Mexico

Stone Energy acquired the Pompano asset from BP at the beginning of 2012.

The rate of production was well below the nameplate capacity of the facilities. Stone Energy wanted to maximise the production throughput by tying back known development targets, exploration targets and third party production. The initial development examined was the subsea tie-back of the Cardona reservoir located approximately six miles south east of the Pompano facility in Mississippi Canyon, Block 29.


  • Subsea architecture:
    • Framing the architecture to move forward into FEED
    • Cardona field layout
    • High level requirements of subsea equipment
  • Configuration and sizing of the flowlines
  • Technical feasibility in terms of onboarding, routing and subsea equipment
  • Potential installation vessels, contracting strategy and methodology
  • Cost estimate and schedule
  • Flow assurance – steady state modelling and analysis
  • HAZID workshop to identify risks associate with the subsea tie-back.


  • Multidiscipline integrated team
  • Focused on client and project delivery
  • Specialising in conceptual engineering
  • Multiple concepts assessed efficiently.
