Beacon Offshore Energy LLC subsidiaries have taken final investment decision to develop the Winterfell oil discovery in the deepwater Gulf of Mexico, the comapny said in a release Jan. 10.
Operated by BOE Exploration & Production LLC (BOE), Winterfell was initially discovered in 2021 with subsequent successful appraisal drilling conducted in 2022 (OGJ Online, Jan. 19, 2021; Jan. 18, 2022).
Beacon holds a 35.41% working interest in the Miocene aged project, which lies primarily in Green Canyon blocks 943, 944, 987, and 988 in water depth of about 5,200 ft.
The field will be developed via a newly installed 13-mile subsea tieback to the Anadarko Petroleum-operated Heidelberg spar in Green Canyon Block 860, Beacon said. Occidental Petroleum acquired Anadarko in 2019 (OGJ Online, Aug. 8, 2019). First oil is expected early in second-quarter 2024. Three initial wells are projected to deliver gross production of about 22,000 boe/d.
Working interest parties include Beacon Offshore Energy Exploration LLC (35.08%), BOE (0.33%), a subsidiary of Kosmos Energy (25.04%), Westlawn GOM Asset 3 Holdco LLC (15.0%), Red Willow Offshore, LLC (12.5%), Alta Mar Energy (Winterfell) LLC (7.55%), and CSL Exploration LP (4.5%).
