LLOG Exploration Company LLC (LLOG) has started production from Spruance field, Ewing Bank (EW) Blocks 877 and 921 in deepwater Gulf of Mexico.
A two-well subsea development is producing about 16,000 b/d and 13 MMcfd gas via a 14-mile subsea tieback to the EnVen Energy Co.-operated Lobster platform in EW 873.
First production was achieved less than three years after the initial exploratory discovery well was drilled.
LLOG and partners discovered Spruance field in mid-2019 via subsalt exploratory well EW 877 #1, which was drilled in 1,570 ft of water to a total depth of 17,000 ft and logged about 150 net ft of oil pay in multiple high-quality Miocene sands (OGJ Online, Oct. 27, 2020).
A second well, EW 921 #1, was drilled from the same surface location as the discovery well to a total depth of 16,600 ft in early October 2020. The well successfully delineated 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.
LLOG operates Spruance field (22.64%) on behalf of partners Ridgewood Energy Corp. (23.89%), EnVen Energy (13.5%), Beacon Asset Holdings Ltd. (11.61%), Houston Energy LP (11.2%), Red Willow Production Co. (11.15%), and CL&F Operating LLC (6%).
