Subsea 7 has been awarded a subsea contract valued at more than US $70 million for a deepwater oil field development operated by Stone Energy in the Gulf of Mexico.

The contractor has won the contract to carry out engineering, procurement, installation and commissioning of flowlines, risers, pipeline structures, and a gas lift umbilical for the Cardona field in Mississippi Canyon Block 29. Project management and engineering work will start immediately at Subsea 7’s offices in Houston.

Offshore operations are due to get underway in the third quarter of next year, with stalking of the risers and flowlines and welding to be performed at the company’s Port Isabel spoolbase.

Stone Energy confirmed earlier this year that an ENSCO 8500 series rig is anticipated to start drilling the Cardona and Cardona South development wells starting in the first quarter of 2014. Each will take between three and four months to drill. The wells will be tied back and produced via the 100% Stone-owned and operated Pompano deepwater platform, starting later in 2014. Stone holds a 65% stake in the Cardona field as operator.

Stone also has several other deepwater wells planned to spud in the GoM before the end of this year and into 2014, including its operated Amethyst prospect (MC 26) in Q4 2013, the LLOG-operated Taggart prospect (MC 816, Stone 23%) in this quarter, the Apache-operated San Marcos prospect (MC 983, Stone 25%) also in the third quarter of this year, the Apache-operated Guadalupe prospect (MC 555, Stone 40%) in late 2013 or early 2014, and the Eni-operated Phinisi prospect (Walker Ridge 719, Stone 20%) late in the fourth quarter of this year or into 2014.
