LLOG wraps up gulf deepwater developments

By OGJ editors

 LLOG Exploration Co. LLC, Covington, La., is wrapping up a multiwell Gulf of Mexico exploration and development program that has allowed it to run one deepwater rig continuously since the Macondo incident, and it has won approval of its first plan of exploration since Macondo.

The Mandy development in 2,465 ft of water on Mississippi Canyon Block 199 will consist of three wells tied back to the Matterhorn TLP production system in Mississippi Canyon 243. The wells have been drilled, completed, and flow tested in the Pliocene, and Matterhorn modification is under way. Mandy is expected to produce at an initial 15,000 b/d of oil and 12 MMcfd of gas starting in the fourth quarter of 2011.

Gross recovery at Mandy is expected to be 10-30 million boe. LLOG has a 50% working interest in two of the wells, with Apache Deepwater LLC owning the other 50%, and LLOG has 100% working interest in the third well. LLOG is operator of the Mandy development.

The Anduin Pliocene discovery in 2,365 ft of water on Mississippi Canyon 754 has been placed on production as a single-well subsea tieback to the Innovator FPS in Mississippi Canyon 711. LLOG’s working interest is 25%.

The Condor Pleistocene Hyal B discovery in 2,949 ft of water on Green Canyon 448 was placed on production in June as a single-well subsea tieback to the Marquette facility in Green Canyon 52. The well has been flowing at a gross 3,000 b/d and 4 MMcfd. LLOG has a 25% working interest.

LLOG’s Goose Pliocene development in Mississippi Canyon 751 will be a single-well subsea tieback to LLOG’s production manifold at Mississippi Canyon 707. LLOG just finished completing the well as a smart selective in two zones. The 12,800-ft zone flow tested 5,300 b/d and 12 MMcfd. The 12,600-ft zone flow tested 2,700 b/d and 16 MMcfd.

Projected start-up for Goose is the first quarter of 2012. LLOG’s working interest is 100%.

LLOG has received approval of the exploration plan for the Son of Bluto II prospect in Mississippi Canyon 387 and 431, which will return the company to its primary focus of exploration.
