Unocal reports GOM deepwater well results

By OGJ editors

HOUSTON, Dec. 29 -- Unocal Corp. has ended drilling operations at its prospect on Mississippi Canyon Block 941 in deepwater Gulf of Mexico where its Sequoia well, drilled to 29,100 ft TD, was completed as a dry hole.

The well was drilled to test the deeper Miocene intervals of the 1999 Mirage discovery, which included an initial well drilled to 16,600 ft and a sidetrack of 22,400 ft.

Operator Unocal has determined that the hydrocarbons encountered in the deeper interval were noncommercial.

Development of the Mirage discovery is now unlikely due to the Sequoia well results.
