Freeport-McMoRan Oil & Gas’s Highlander well in St. Martin Parish tested at 43.5 million cubic feet of natural gas per day, according to parent company Freeport McMoRan.

The onshore well was drilled to a depth of 29,400 feet in 2014. Freeport-McMoRan Oil & Gas has identified a number of prospects in the Highlander area, where the company controls the rights to more than 60,000 acres.

Freeport-McMoRan Oil & Gas and its partners expect to begin production this year. The company owns a 72 percent working interest in the well. The other owners include Energy XXI LTD, 18 percent, and W. A. “Tex” Moncrief Jr., 10 percent. The Gulf Coast Ultra-Deep Royalty Trust owns 3.6 percent of the proceeds from the gas sold in the Highlander area.
