LLOG Exploration Co. LLC struck oil at a second Spruance well in the deepwater Gulf of Mexico, the Houston-based LLOG said in an Oct. 26 release.

The oil find continues the privately held E&P company’s drilling success at its Spruance discovery made by LLOG and its partners in mid-2019. LLOG also announced on Oct. 26 the finalization of development plans for the field.

“We are pleased to announce the discovery and subsequent delineation of the Spruance prospect in the deepwater Gulf of Mexico,” Philip LeJeune, president and CEO of LLOG, said in a statement on Oct. 26. “The results of the second well confirmed our understanding of the field’s reserve potential.”

Spruance is located in Ewing Bank (EW) 877/921 and was initially discovered via a subsalt exploratory well in 1,600 ft of water.

The EW 877 #1 well was drilled to a total depth of 17,000 ft and logged approximately 150 net ft of oil pay in multiple high-quality Miocene sands. 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.

The second well 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.

LLOG is the operator at Spruance and owns a 22.64% working interest with partners Ridgewood Energy (23.89%), Houston Energy LP (11.2%), Red Willow Production Co. (11.15%), EnVen Energy Corp. (13.5%), CL&F Resources LP(6%) and Beacon Asset Holdings (11.61%).

In the Oct. 26 release, LLOG said the company and its partners signed a production handling agreement in July for the processing of Spruance reserves via a 14-mile subsea tieback to the EnVen-operated Lobster platform in EW 873. The Lobster platform is located 130 miles south of New Orleans in 775 ft of water.

“We are also pleased to have finalized development plans for the field,” LeJeune said of the agreement in his statement adding that by utilizing the EnVen-operated Lobster facility, LLOG will be able to develop Spruance in a “cost-effective manner with an efficient cycle-time.”
