Lafayette-based Stone Energy Corp. has begun producing oil from its Cardona deep-water project in the Gulf of Mexico.

Two wells, located roughly 100 miles southeast of New Orleans, began producing in late November, and Stone expects to ramp up production over a four-week period. The wells’ combined production is projected to reach the equivalent of 12,000 barrels per day during the test period.

The Cardona subsea facility allows Stone to tie in two additional wells, which are scheduled for drilling in 2015. Those wells are expected to produce the equivalent of 10,000 barrels of oil per day.
