Freeport-McMoRan Inc.reported its exploration and production (E&P) unit completed a successful production test from an ultra-deep Highlander natural gas discovery well onshore south Louisiana. Freeport-McMoRan Oil & Gas (FM O&G) said the production test indicated a flow rate of approximately 43.5 MMcf/d, with approximately 21.5 MMcf/d net to FM O&G, which along with its partners expects to begin production next year, using facilities in the immediate area. FM O&G said the Highlander discovery well had been drilled to a 29,400-foot depth in the first quarter this year. The E&P said it has identified multiple prospects in the Highlander area, in which it controls more than 60,000 gross acres. FM O&G is the Highlander well operator, holding a 72% working interest and an approximate 49% net revenue interest.
