Production has commenced from the Tubular Bells Field located in the Mississippi Canyon area of the deepwater Gulf of Mexico (GoM), Hess said in a news release. Hess holds a 57.14% interest in the Tubular Bells Field and is the operator. Chevron U.S.A. Inc. has a 42.86% interest.

Following a ramp-up period, Tubular Bells is expected to deliver gross production of about 50,000 boe from three producing wells by year-end 2014.

The Tubular Bells Field was discovered in 2003, and the development was sanctioned in October 2011. It lies in about 1,310 m (4,300 ft) of water 217 km (135 miles) southeast of New Orleans in the GoM.

Tubular Bells uses the first classic spar built in the U.S. The design and construction were done entirely in the U.S.
