HOUSTON, July 13 -- Mariner Energy Inc., Houston, has a discovery on the Yosemite prospect on Green Canyon 516 in the Gulf of Mexico that it plans to tie back 16 miles to the Allegheny development.

The discovery well, in 3,900 ft of water, reached 11,745 ft TD and found multiple hydrocarbon-bearing zones. Mariner, with partners Agip Petroleum Co. Inc. and Noble Drilling Exploration Co., has temporarily suspended the well.

The partners' proposed plan includes development with Mariner-Agip's King Kong field, on Green Canyon 472, 473, and 517, as revealed earlier this year (OGJ Online, June 19, 2001).

The fields will be tied back to Agip's Allegheny mini-TLP on Green Canyon 254.

Though a development plan has not been finalized, Yosemite well and the two King Kong wells are expected to come on stream by Dec. 31 at a combined initial rate of 150 MMcfd.

Operator Mariner owns 44% of Yosemite, Agip owns 50%, and Noble Drilling Exploration owns 6%.
