The purpose of this study is to provide a technical evaluation of the feasible development concepts for selected oil discoveries in the Barents Sea, named; Goliat, Johan Castberg, Alta, Gohta, and Wisting. The study is unique to the extent that includes consideration of all required elements for a field development project; subsurface conditions, reservoir engineering, production profiles, drilling schedule, subsea and topside facilities, infrastructure (existing and planned) and environmental concerns in the Barents Sea.
The selected method was based on high-level of facts, reservoir data, recoverable reserves, in place volumes and other available data, which all originates from public resources and literature. The collected data were systemized into our in-house developed profile generator tool. A predefined drilling schedule was implemented in the profile generator, and output was production rate and cumulative production.
Technical and commercial evaluation on three different development concept scenarios for the selected oil discoveries has been presented. Scenarios were defined based on using available and future planned infrastructure in the region. It has been shown that the distance between discoveries and the shoreline in the Barents Sea is relatively large, and resources are lower than what is commercially needed to evaluate as a stand-alone solution. The results of the study show that discoveries may be developed through a coupled reservoir solution.
