field development planning: case study

capability:field development planning

We start with the end in mind, bringing an integrated and holistic approach to field development planning, which is uniquely integrated across the technical, strategic and commercial.


io provided technical and commercial insights, including alternative financing models, to change the initial development plan to one that provided highest overall value to the client.

value driver

io used an integrated and holistic approach to meet the client value drivers of speed to market, minimising capex to 1st gas & execution risk, with an ability to enable external finance.


The study recommended a deep water FPSO with dew-pointed gas export to beach which offered best overall value and superior operating regime when compared with other cases.

io approach – leverage project finance based consortium

Our client wanted to invest in offshore blocks and needed a development concept to meet their value drivers.

io approach

4 initial development cases were identified and evaluated:

  • using existing local analogue – subsea wells and 100km infield pipeline to a shallow water platform (gas dew pointing and liquid export) with additional 10km dry gas and liquid pipelines to onshore receiving facilities including gas metering and liquid storage and export
  • subsea wells to a deep water FPSO (gas dew pointing, liquid and offloading) and a 110km
    gas pipeline to onshore receiving facilities including gas metering
  • subsea wells and 110km multiphase pipeline to onshore production facilities including gas dew pointing and metering, liquid storage and export.
  • subsea tie-back to existing facilities

actions taken

  • we conducted a concept verification study and cost estimate of a large deep water gas and condensate evelopment with an onshore gas market including processing and pipeline facilities
  • this study was executed over 6 weeks and utilised io’s in-house concept evaluation and cost estimating tools
