Williams Announces Deepwater Tieback Agreement at Devils Tower

Williams (NYSE: WMB) announced today that it has reached a tieback agreement with LLOG Exploration Offshore, L.L.C. (LLOG) to provide offshore natural gas and oil gathering and production handling services for the Taggart development at Williams’ Devils Tower Spar, which is located 140 miles southeast of New Orleans in the Mississippi Canyon area of the Gulf of Mexico. In addition to gathering and production handling, Williams will provide onshore gas treatment and processing services to support the Taggart development.

“We are pleased to provide the full spectrum of midstream capabilities to another deep-water producer in the Gulf,” said Micheal Dunn, Chief Operating Officer for Williams. “Interconnected unlike any other, our offshore and onshore infrastructure allows us to maximize value for our customers by providing a safe, seamless and efficient direct path to market. We look forward to serving LLOG and capturing the full value of these important deep-water resources for our nation’s economy.”

Williams will leverage its existing footprint and system capabilities to gather Taggart crude and natural gas production through Williams’ Mountaineer and Canyon Chief pipeline systems. The natural gas will be delivered to Williams’ Mobile Bay Processing Plant, and the natural gas liquids will be fractionated and marketed at the Baton Rouge Fractionator (Williams 33% owner) in Louisiana.

Taggart is expected to come online in early 2022, and the reserves are expected to produce approximately 27 million barrels over eight years.

Williams is well known in the Gulf of Mexico as an experienced and reliable operator providing top-quality midstream services producers have grown to trust. The company’s Gulf of Mexico assets offer producers the full value chain of capabilities – from well head gathering to processing to fractionation and transmission. Williams owns and operates 3,500 miles of natural gas and oil gathering and transmission pipelines, along with 1.8 billion cubic feet per day of cryogenic processing capacity and 60,000 barrels per day of fractionation capacity that span the Gulf of Mexico. The company has ownership in two floating production platforms, multiple fixed leg utility platforms, and numerous other related facilities.
