HOUSTON, Jan. 30 -- Plains Exploration & Production Co., Houston, has confirmed the Friesian deepwater discovery in the Gulf of Mexico and plans to deepen the well to 32,500 ft to test sands that flowed at high rates at the giant Tahiti structure two block west.

Shell Offshore Inc. cut more than 120 ft of net oil pay at the Friesian-1 discovery well on Green Canyon Block 599 in November 2006. TD is 29,414 ft.

The Plains-operated Friesian-2 confirmation well in Block 643 at 3,300 ft south of the discovery well is at 28,989 ft and cut 389 net ft of oil-saturated Miocene sands. It encountered 219 net ft of high-quality oil pay in three main sand lobes totaling more than 210 ft thick and a fourth sand lobe with 179 ft of oil pay that wasn't fully evaluated.

The four pay sands, all full to base with oil, are the uppermost field pays at Tahiti field 8 miles west across the basin syncline. Existing data show strong geologic and pressure correlation with the initial Miocene field pay sands at Tahiti.

Plains and its partners plan to deepen Friesian-2 to test the main equivalent sands at Tahiti such as the M15, M18, M21A, and M21B, several of which have flow-tested at more than 25,000 b/d of oil. The Ocean Monarch semisubmersible is expected to arrive in March to deepen Friesian-2.

Early stage commercialization initiatives for Friesian production are under study with multiple parties to target initial production by 2012, Plains said.
