LONDON – Jersey Oil & Gas (JOG) favors a new four-legged steel platform for its Greater Buchan Area (GBA) development in the UK central North Sea.
This would be located at the Buchan field, with production wells for the Buchan redevelopment and the J2 structure drilled from the platform using a heavy duty jackup.
The platform would contain production facilities to process fluids to export specification, with future oil and gas production sent through a subsea pipeline to nearby infrastructure. In addition, the facilities would receive from other field developments in the region via subsea tiebacks.
Discussions with operators of oil and gas pipeline systems have confirmed entry specification requirements and tie-in locations.
A new platform, JOG claimed, would ensure a production life of at least 25 years for the GBA, serving as a hub for the company’s discovered and development-ready resources, and additional discoveries owned by JOG; third-party discoveries and prospective resources within the GBA catchment area; and otherwise stranded reserves from shut-in regional production hubs.
This could lead to an area collaboration with third-party operators to determine whether the GBA facilities could serve as a regional hub.
JOG has also been assessing options to eliminate CO2 emissions associated with power generation on the platform. The most attractive, technically feasible solution for platform electrification would be via a new subsea cable connected to the UK’s national grid: this could eliminate gas turbines and fuel gas treatment utilities from the platform.
In addition, the GBA could serve as a power hub enabling wider electrification of third-party infrastructure in the Outer Moray Firth: collaboration could improve the platform electrification economics.
