Beacon Offshore Energy LLC, Houston, started oil production at the Winterfell development in the Green Canyon area of the US Gulf of Mexico.
Winterfell, a Miocene-aged field discovered in 2021 in water depth of 5,400 ft, is being developed in phases through a 13-mile subsea tieback to the host platform. The initial two production wells were drilled and completed with subsea hookup in April 2024. The wells are online and ramping up production, said partner Kosmos Energy Ltd. in a July 3 release. A third well is being drilled and is expected to be online by the end of third-quarter 2024. Together, the three initial wells are expected to deliver gross production of about 20,000 boe/d, Kosmos said.
Final investment decision was made on the project early this year (OGJ Online, Jan. 10, 2024). At the time, the operator said the project’s first phase, with five wells in total, is expected to deliver around 100 MMboe with upside from subsequent phases.
The Winterfell unit consists of Green Canyon blocks 899, 900, 943, 944, 987 and 988 with follow-on opportunities in adjacent blocks.
Beacon subsidiary BOE Exploration & Production LLC is operator. Partners are Kosmos Energy Ltd., Westlawn Americas Offshore, Red Willow, Alta Mar Energy, and CSL Exploration.
