Chevron Corporation today announced a new oil discovery at the Guadalupe prospect in the deepwater U.S. Gulf of Mexico.
The Keathley Canyon Block 10 Well No. 1 encountered significant oil pay in the Lower Tertiary Wilcox Sands. The well is located approximately 180 miles off the Louisiana coast in 3,992 feet of water and was drilled to a depth of 30,173 feet.
“The discovery further demonstrates Chevron’s exploration capabilities,” said George Kirkland, vice chairman and executive vice president, Upstream, Chevron Corporation. “Guadalupe builds on our already strong position in the deepwater U.S. Gulf of Mexico, a core focus area where we expect significant production growth over the next two years.”
“The Guadalupe discovery adds momentum to our growing business in North America,” said Jay Johnson, senior vice president, Upstream, Chevron Corporation. “Our deepwater exploration and appraisal program continues to unlock important resources in the Gulf of Mexico.”
“The company expects additional Gulf of Mexico production from the Tubular Bells and Jack/St. Malo projects by the end of the year.”
“Chevron subsidiaries are among the top producers and leaseholders in the Gulf of Mexico, averaging net daily production of 143,000 barrels of crude oil, 347 million cubic feet of natural gas, and 15,000 barrels of natural gas liquids during 2013,” said Jeff Shellebarger, president, Chevron North America Exploration and Production Company. “The company expects additional Gulf of Mexico production from the Tubular Bells and Jack/St. Malo projects by the end of the year.”
Chevron subsidiary Chevron U.S.A., Inc. began drilling the Guadalupe well in June 2014. More tests are being conducted on the discovery well and additional appraisal wells will be needed to determine the extent of the resource.

Chevron U.S.A., Inc., with a 42.5 percent working interest in the prospect, is the operator of the Guadalupe discovery well. Guadalupe co-owners are BP Exploration & Production, Inc. (42.5 percent) and Venari Resources LLC (15 percent).
Neftegaz America Shelf LP (Neftegaz), an indirect independent subsidiary of Russia’s state-run oil company Rosneft, has acquired 30 percent interest in 20 deepwater exploration blocks in the Gulf of Mexico held by ExxonMobil, under an agreement signed by the two companies.
The 20 blocks have a total area of approximately 111,600 acres (450 square kilometers) in water depths ranging between 2,100 and 6,800 feet (640 and 2,070 meters). Seventeen are located in the Western Gulf of Mexico and three are in the Central Gulf of Mexico.
ExxonMobil retains 70 percent interest in the blocks and remains operator. Analysis of seismic data is under way. There is currently no production on the blocks.
Rosneft and ExxonMobil continue to implement the Strategic Cooperation Agreement signed in 2011, under which the companies and their subsidiaries plan to undertake joint exploration and development of hydrocarbon resources in Russia and other countries and to share technology and expertise. Under subsequent agreements between Neftegaz and ExxonMobil, Rosneft’s subsidiary gained the option to acquire interest in 20 blocks of its choosing from among ExxonMobil’s Gulf of Mexico exploration portfolio. The latest agreement represents the exercise of that option.
The agreement was signed by Igor I. Sechin, president of Rosneft, and Stephen M. Greenlee, president of ExxonMobil Exploration Company.
“ExxonMobil has a long history of safe oil and gas exploration in the Gulf of Mexico using state-of-the-art safety and environmental protection systems,” said Greenlee. “We look forward to working with Rosneft and its affiliates to explore these blocks using our leading-edge exploration and development technology and deepwater execution expertise.”
Sechin said, “This agreement provides Rosneft and its affiliates with access to one of the world’s most prolific basins. We believe joint efforts of our companies will ensure the most efficient development of these blocks, with application of the latest technologies and adhering to high environmental standards. Moreover, experience and knowledge acquired in the process may potentially be used when developing deepwater blocks in Russia, including in the Tuapse Trough in the Black Sea as envisaged under the Strategic Cooperation Agreement.”
ExxonMobil and Rosneft continue to implement a program of staff exchanges for technical and management employees to help strengthen the working relationships between the companies and provide valuable career development opportunities for employees of both companies.
The 20 blocks are:
Western Gulf of Mexico – Alaminos Canyon 569, 612, 613, 655, 656, 657, 698, 699, 700 and 701; East Breaks 429, 471, 472, 473 and 515; Keathley Canyon 529 and 573.
