Lafayette-based Stone Energy Corp. announced a discovery at its deep gas LaPosada Prospect in Vermilion Parish.

Stone has an approximate 33 percent interest in the well, which reached a depth of 18,550 feet. A pipe stuck in the well prevented the operator, PetroQuest, from obtaining all the well data but the company confirmed a pay zone, the portion of the reservoir capable of commercial production, of 37 feet.

The well has a proposed vertical depth of 19,300 feet and Stone expects to be on production by early 2012.
