Petroleos Mexicanos, or Pemex, said it has confirmed the existence of "five wet gas deposits" in the Gulf of Mexico after drilling a well to a water depth of 2,157 meters (7,070 feet).

The new find makes the Kunah-1 well - located in the Catemaco Fold Belt at a spot about 125 kilometers (77 miles) northeast of the Mexican Gulf coast port of Veracruz - the state monopoly's most productive deepwater well, Pemex said in a statement.

The five deposits discovered in drilling by the Centenario rig have depths ranging between 2,845 and 4,103 meters (9,327 and 13,450 feet), Pemex said.

Production tests in the area show "34 million cubic feet of wet gas per day and 110 barrels of liquids," the state-owned oil giant said.

Pemex said it estimates this latest find holds 3P, or proven, possible and probable, reserves of between 1.5 and 2 trillion cubic feet of gas.

It added that the discovery expands its portfolio of production opportunities in the Catemaco Fold Belt, which are "equivalent to 300-400 million barrels, of which about 10 percent are crude."

This project is part of the exploratory work that Pemex's exploration and production unit is carrying out in the deepwater Gulf of Mexico in a bid to boost production, which has fallen about a quarter from a peak of 3.4 million barrels of oil per day in 2004.

Work at Kunah-1 and the Lakach-1 and Piklis-1 wells began in 2006 and has resulted in an increase in the number of productive accumulations in the northern part of the belt. EFE
