LLOG Exploration Offshore has sanctioned its Taggart discovery, which will developed via tieback to the nearby Williams-owned Devils Tower Spar, in the U.S. Gulf of Mexico, according to a news release.
Initial development plans at Taggart include the completion and tieback of two wells. First production is anticipated in 2022.
The news was delivered June 29 nearly seven years after the discovery well, drilled to a depth of 11,562 feet, hit 97 feet of net pay in two Miocene objectives. LLOG said two subsequent appraisal wells were drilled in 2015 and 2019, respectively encountering 147 feet and 84 feet of net pay.
Taggart is located on Mississippi Canyon Block 816 in about 5,650 feet of water.
The Williams Cos. announced June 17 a tieback agreement with LLOG to provide offshore natural gas and oil gathering and production handling services for the development. In addition to gathering and production handling, Williams will provide onshore gas treatment and processing services to support Taggart.
LLOG CEO Philip LeJeune said Taggart has reserves totaling about 27 MMboe.
“We look forward to the successful development of this deepwater asset,” LeJeune said.
U.S. natural gas production is declining as domestic consumption falls but global demand, including for LNG, is adding to optimism.
The latest discovery was made by the Mako-1 well drilled about 10 km southeast of the Liza Field.
The Vaca Muerta Formation in the Neuquén Basin has technically recoverable resources of 308 trillion cubic feet of natural gas and 16 billion barrels of oil and condensate, according to the U.S. Energy Information Administration.
