Repsol Reports Two New Oil Finds In Gulf Of Mexico's Shenzi Deepwater Field

Published: 30-Oct-2009

Repsol YPF SA (Repsol) and its partners, BHP Billiton and Hess Corporation (Hess) made two new finds in the Shenzi field in the Gulf of Mexico. In addition to a new pay found in the existing G104 well, Repsol found oil in the Shenzi-8 well, helping increase future production potential for the area, where output is already is already above expectations. Repsol owns a 28% stake on the Shenzi development. BHP Billiton operates the consortium, with a 44% stake, and Hess owns the remaining 28%.

The Shenzi G104 well, drilled to a depth of 25,605 feet encountered a total of 555 feet of net oil pay. The well had encountered net oil pay of 68 feet in the targeted lower Miocene interval, in line with expectations. An additional 497 feet of net oil pay was also found in the well in two shallower intervals. The well began producing from the lower Miocene pay in September 2009, and further evaluation is underway to assess future development potential of these shallower intervals.

In addition, the Shenzi-8 appraisal well, drilled in November 2008, to a total depth of 25,904 feet encountered about 100 feet of net oil pay in the Miocene age reservoirs, opening additional potential to the Shenzi North Flank. These are the same reservoirs as have been successfully developed and are currently producing in the Shenzi South Flank. The well also encountered an additional 30 feet of net oil pay in a shallower reservoir interval.

The platform already installed at Shenzi is producing in excess of 120,000 barrels of oil per day, 20% more than the facility’s design capacity and in excess of production expectations.

Production in the Shenzi field began in March 2009 from a platform located in the Green Canyon 653 block 195 kilometers off the Louisiana coast (USA). Production currently comes from 10 wells connected to the platform and is expected to be expanded to 15 producing wells.
