LONDON, Oct. 26 -- Eni SPA expects to increase the estimated reserves of the deepwater Longhorn gas discovery in the Gulf of Mexico after testing its last appraisal well, but it did not indicate by how much.

The well found 127 m of net pay in multiple sands after reaching a TD of 4,228 m. Eni said it encountered a stratigraphically deeper zone than in two exploratory wells drilled in 2006. "The initial analysis indicates good reservoir quality," it added.

Longhorn will be developed via a subsea tie-back to a host platform with first production scheduled for 2009. Eni plans to sanction the Longhorn development by December 2007.

Eni holds additional interests in other leases in the "Greater Longhorn Area," which is one of its core areas in the gulf, and has scheduled further exploration activity in 2008.

Longhorn is 195 km southeast of New Orleans in Mississippi Canyon Block 502.

Eni is the operator with a 75% working interest and Nexen Petroleum Offshore USA Inc. holds a 25% working interest.
