LLOG Exploration Co. LLC finalized plans to develop the Spruance discovery in the deepwater Gulf of Mexico following drilling results delineating the prospect.
Spruance was discovered in mid-2019 via a subsalt exploratory well in 1,600 ft of water in Ewing Bank (EW) 877/921. EW 877 #1 was drilled to a total depth of 17,000 ft and logged about 150 net ft oil pay in multiple high-quality Miocene sands.
A second well, EW 921 #1, was drilled from the same surface location to a total depth of 16,600 ft in early October. It successfully delineated the main field pays and logged additional oil pay in the exploratory portion of the well, finding a total of over 200 net ft of oil. Both wells are scheduled for completion in 2021, with first oil sales scheduled for early 2022.
In July, LLOG and partners signed a production handling agreement for processing of Spruance reserves via a 14-mile subsea tieback to EnVen-operated Lobster platform in EW 873 some 130 miles south of New Orleans in 775 ft of water.
LLOG is operator at Spruance (22.64%) with partners Ridgewood Energy (23.89%), Houston Energy (11.2%), Red Willow (11.15%), EnVen (13.5%), CL&F (6%), and Beacon Asset Holdings (11.61%).
