Mexico's state-owned oil company Pemex said that it has discovered six new crude oil deposits in the Gulf of Mexico.

The discoveries include two super light crude oil deposits in deep waters and four light crude deposits in shallow waters.

The company, which has been facing output declines for more than a decade, also plans to drill 30 exploratory wells next year.

A Pemex spokesman was quoted by Reuters as saying that the discoveries were a made couple of months ago but were not disclosed in order to weigh the reserves and their commercial viability.

The firm said that it has already drilled the Nobilis-1 well in the oil-rich Cinturon Plegado de Perdido area, which is in deep waters in the Gulf of Mexico.

The well has a depth of 3,000 meters to the ocean floor, while its total depth is over six kilometers.

Pemex said the crude in two discoveries in deep waters has a super light gravity of over 40 degrees API.

It added the two wells could “eventually” produce 15,000 barrels per day.

The oil major estimated that the two wells could have proven, probable and possible (3P) reserves of between 140 million to 160 million barrels of oil equivalent (boe).

It is seeking partners for a joint venture to develop the deep water deposits, which are close to the Trion field, The Wall Street Journal reported.

Pemex was quoted by the publication as saying: “This find strengthens the strategy of partnerships in Perdido.”
