Offshore

As gas flaring becomes more unacceptable from political and environmental viewpoints, proposals for new oilfield projects, and even extended well tests, in remote or deep water locations must increasingly demonstrate how the associated gas will be processed without continuous flaring.

Gas re-injection offers a solution but this can be expensive in ultra deep-water, may reduce ultimate recoverable reserves, and is not practical for EWT projects.

Likewise gas export schemes may not be feasible, practical or economical for remote fields or EWT projects.

There is a clear market demand for a small scale offshore associated gas solution. Political pressure is driving more stringent environmental regulation of E&P activity around the globe, particularly the development of new oil and gas discoveries. National governments are applying legislation on associated gas utilization to varying degrees. The World Bank influences this, through its Global Gas Flaring Reduction Forum and the pathways this facilitates to project finance.

In addition, the IOC’s are applying self-regulation, their corporate environmental polices preventing development plans being considered that involve continuous gas flaring for long periods.

Yet there is a wide technology gap considering the current, and many of the emerging, management options for non-commercial associated gas. FLNG and CNG, with their high infrastructure costs, address gas flow rates of the order of 200MMscf/d and above. Furthermore CNG is highly sensitive to the distance to shore (and market), likewise Gas-to-Wire.

SBM Offshore and CompactGTL have combined efforts to offer an optimized FPSO with an integrated GTL plant for EWT service or small field developments. The concept is well advanced and ready for field specific FEED.

Key Concept Design Features:

  • An Extended Well Test Facility for a wide range of water depths
  • Ability to quickly relocate from field to field for a program of EWTs
  • Minimise flaring by adopting CompactGTL technology for conversion of all surplus associated gas (after fuel) into Synthetic Crude Oil
  • Maximise integration between CompactGTL  process and the FPSO topsides process, utilities and marine systems for improved operability and Capex / Opex optimisation
  • Reservoir properties based on a wide range of inlet compositions
  • Extendable to full field developments
  • Ideally suited for remote, deep water locations, and typically for fields with low Gas to Oil ratios
