Chevron in ‘significant’ oil find in U.S. Gulf of Mexico
- Exploration & Production
U.S. oil major Chevron has made what it says is a significant oil discovery at the Ballymore prospect in the deepwater U.S. Gulf of Mexico.
Ballymore is located in the Mississippi Canyon area of the U.S. Gulf of Mexico, approximately three miles from Chevron’s Blind Faith platform, in water depth of 6,536 feet.
The initial Ballymore well reached total measured depth of 29,194 feet and encountered more than 670 feet net oil pay with excellent reservoir and fluid characteristics. A sidetrack well is currently being drilled to further assess the discovery and begin to define development options, Chevron said.
“The Gulf of Mexico deepwater is an integral part of our company’s long-term strategy,” said Jeff Shellebarger, President of Chevron North America Exploration and Production. “This discovery is an important addition to our portfolio, especially with its combination of size, quality and proximity to existing infrastructure.”
Located in water depth of about 2,000 meters and 120 kilometers from the Louisiana coast, the Ballymore prospect covers four blocks in the Norphlet play, including Block MC 607 where the discovery was made.
Chevron subsidiary Chevron U.S.A. Inc. is the operator with a 60 percent working interest in the Ballymore prospect. The co-owner is Total E&P USA Inc. (40 percent).
Total’s President Exploration & Production Arnaud Breuillac said: “This major discovery gives us access to large oil resources and follow on potential in the emerging Norphlet play. It also demonstrates all the interest of Total’s GoM farm-in agreement with Chevron, where we acquired a 40% interest in Ballymore. While already deemed commercially viable, we will work together on the appraisal of this discovery and a cost-effective scheme to ensure a rapid, low breakeven development.”
Total’s acquisition of a 40% working interest in Ballymore was part of an exploration agreement with Chevron (60%, operator) signed in September 2017 that included seven prospects covering 16 blocks in the Norphlet (Eastern GoM) and the Wilcox (Central GoM) plays.
