LLOG Exploration Offshore LLC will participate in the drilling of a well to delineate Repsol E&P USA Inc.’s 2014 Leon oil discovery in the Lower Tertiary play of the deepwater Gulf of Mexico (OGJ Online, Oct. 28, 2014).

Under an asset exchange and new joint operating agreement, LLOG will operate the well on Keathley Canyon Block 642 with a 33% working interest.

The Leon discovery well was drilled to 32,000 ft TD in 6,000 ft of water, encountering nearly 500 ft of net oil pay.

Repsol will acquire a 30% interest from LLOG in the 2011 Moccasin discovery on Keathley Canyon Block 736. The discovery well, drilled by Chevron Corp. to deeper than 31,000 ft in more than 6,500 ft of water, found nearly 400 ft of net oil pay (OGJ Online, Sept. 6, 2011).

LLOG acquired the license in 2017 and is operator. It retains a 31.35% working interest in Moccasin, which is less than 20 miles from Leon.

Leon is 31 miles northwest of Repsol’s 2009 Buckskin discovery, now operated by LLOG, in 6,800 ft of water on Keathley Canyon blocks 785, 828, 829, 830, 871, and 872 (OGJ Online, Feb. 6, 2009). LLOG said Buckskin production will begin in mid-2019 after initial development involving two wells drilled to about 29,000 ft into Lower Tertiary pay.
