A Mathematical Programming Approach to Determine Optimal Tieback Development Concepts of Two Offshore Oil Fields in the Barents Sea

摘要

In this paper, we present a mathematical programming approach to evaluatethe conceptual study of regional integrated development for Alta-Gohtadiscoveries in the Barents Sea. Two alternative scenarios are investigated,the first considers to tieback Alta-Gohta to a field that is 60 km away,Johan Castberg, and the second to tieback the field to Goliat, anotherfield at 100 km further. A sensitivity analysis in terms of CAPEX andOPEX is performed to assess the trade-off between selecting the host tobe Johan Castberg or Goliat. The results indicate that the profitabilityand host selection for a tieback development plan of Alta-Gohta is highlydependent on the start time and the costs of the project.
