French oil giant Total has made a major oil discovery in the Ballymore prospect, located deep offshore in the U.S. Gulf of Mexico (Eastern GoM).
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.
Total said in a statement that the well was drilled to a final depth of 8,898 meters and encountered 205 meters of net oil pay in a high quality Norphlet reservoir. A sidetrack well is now ongoing to confirm the upside potential.
“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 per cent 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,” said Arnaud Breuillac, president Exploration & Production at Total.
“Ballymore is the largest discovery by Total in the prolific Gulf of Mexico and bolsters our new exploration strategy put in place since 2015,” added Kevin McLachlan, senior vice president Exploration at Total.
Total’s acquisition of a 40 per cent working interest in Ballymore was part of an exploration agreement with Chevron (60 per cent, operator) signed in September 2017 that included seven prospects covering 16 blocks in the Norphlet (Eastern GoM) and the Wilcox (Central GoM) plays.
