The oil and gas giant, Total has announced a major oil discovery in the Ballymore prospect, located deep offshore in the U.S. Gulf of Mexico (Eastern GoM). The well was drilled to a final depth of 8,898 m and encountered 205 m 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% 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 break-even development”, said Arnaud Breuillac, president of E&P at Total.Located in water depth of about 2,000 m and 120 km from the Louisiana coast, the Ballymore prospect covers four blocks in the Norphlet play, including Block MC 607 where the discovery was made. 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.“Ballymore is the largest discovery by Total in the prolific Gulf of Mexico and bolsters our new exploration strategy put in place since 2015,” commented Kevin McLachlan, senior V.P. of exploration at Total.
