Chevron Corporation is targeting to increase oil and natural gas recovery at the company’s existing Jack/St. Malo and Tahiti facilities in the deepwater U.S. Gulf of Mexico.
Chevron has started water injections at two projects, the company said in a news release, adding that operations at the Jack/St. Malo and Tahiti facilities “produce some of the world’s lowest carbon intensity oil and gas”.
“Delivery of these two projects maximizes returns from our existing resource base and contributes toward growing our production to 300,000 net barrels of oil equivalent per day in the U.S. Gulf of Mexico by 2026,” Bruce Niemeyer, Chevron Americas Exploration & Production President, said. “These achievements follow the recent production startup at our high-pressure Anchor field, reinforcing Chevron’s position as a leader in technological delivery and project execution in the Gulf”.
At the Jack/St. Malo facility, Chevron said it achieved first water injection at the St. Malo field, the company’s first waterflood project in the deepwater Wilcox trend. “The project was delivered under budget, with the addition of water injection facilities, two new production wells, and two new injection wells,” the company noted. It is expected to add approximately 175 million barrels of oil equivalent (MMboe) to the St. Malo field’s gross ultimate recovery.
The St. Malo field and Jack/St. Malo facility are approximately 280 miles (450 kilometers) south of New Orleans, Louisiana, in approximately 7,000 feet (2,134 meters) of water. Since the fields started production in 2014, Jack and St. Malo together have cumulatively produced almost 400 MMboe, according to the release.
At the Tahiti facility, located approximately 190 miles (306 kilometers) south of New Orleans in around 4,100 feet (1,250 meters) of water, Chevron started injecting water into its first deepwater Gulf producer-to-injector conversion wells. The project included installation of a new water injection manifold and 20,000 feet of flexible water injection flowline, the company outlined.
The Tahiti facility recently surpassed 500 million gross barrels of oil-equivalent cumulative production due to multiple development projects since the start of operations in 2009, Chevron said. The company further noted that it continues to study advanced drilling, completion, and production technologies that could be employed in future development phases at Tahiti and Jack/St. Malo with the potential to further increase recovery from the fields.
Chevron, through its subsidiary Union Oil Company of California, is the operator of the St. Malo field and, together with its subsidiary Chevron U.S.A. Inc., holds a 51 percent working interest. The other co-owners are MP Gulf of Mexico, LLC with a 25 percent interest, Equinor Gulf of Mexico LLC with 21.5 percent, Exxon Mobil Corporation with 1.25 percent; and Eni Petroleum US LLC with 1.25 percent.
Chevron U.S.A. Inc. is the operator of the Tahiti facility with a 58 percent working interest. Co-owners Equinor Gulf of Mexico LLC and TotalEnergies E&P USA, Inc. hold 25 percent and 17 percent stakes, respectively.
In August, Chevron announced the successful deployment of high-pressure deepwater technology as it began production of oil and natural gas from the Anchor field on the U.S. Gulf of Mexico (GOM).
The project employs a semisubmersible floating production unit (FPU) with a daily capacity of 75,000 gross barrels of oil and 28 million gross cubic feet of gas, which will supply Gulf Coast markets in the U.S., according to an earlier statement.
The Anchor development will have seven subsea wells tied to the FPU, stationed in the Green Canyon area about 140 miles off the Louisiana coast and located on waters about 5,000 feet. Discovered in 2014, the field holds potentially recoverable resources of around 440 MMboe.
Chevron operates Anchor with a 62.86 percent stake through Chevron USA Inc. TotalEnergies SE owns the remaining 37.14 percent via TotalEnergies E&P USA Inc.
