January 10, 2024

As the Winterfell operator, Beacon holds a 35.41% working interest in the Miocene-aged project located in Green Canyon blocks 943, 944, 987, and 988, with a water depth of approximately 5,200 ft.

Winterfell was initially discovered in 2021, with subsequent successful appraisal drilling conducted in 2022. The field will be developed via a newly installed 13 mile subsea tieback to the Heidelberg spar located in Green Canyon Block 860, operated by Anadarko Petroleum Corporation. 

First oil is expected to occur early in the second quarter 2024, and from three initial wells projected to deliver gross production of approximately 22,000 boepd. 

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%), CSL Exploration, LP (4.5%).

Commenting on the announcement, Scott Gutterman, CEO, said, “At Winterfell, we are unlocking the sub-salt field’s potential via the execution of horizontal drilling technology applied to open hole completions while securing access to the nearby Heidelberg spar and associated downstream infrastructure with available ullage.  The Winterfell development once again demonstrates the ability to produce oil and natural gas in the U.S. Gulf of Mexico with a lower carbon footprint than almost all other regions.”

Beacon Offshore Energy is a Houston, Texas-based exploration and production company formed in 2016, with a focus on exploring, developing and acquiring upstream oil and gas properties in the deepwater Gulf of Mexico. Beacon is actively focused on developing its resource position including its operated Shenandoah project which remains on track for first oil by end of year 2024. The company currently holds interests in 89 deepwater leases with a net resource potential of over 400 MMboe.
