Six weeks after Mexico’s Petroleos Mexicanos (Pemex) reported its first deepwater discovery in the Gulf of Mexico, the producer said it has struck another big gusher nearby.
In late August Pemex reported the Trion 1 discovery in the Perdido Fold Belt near the Mexico-U.S. maritime boundary that may contain up to 400 million bbl of reserves (see Daily GPI, Aug. 31).
However, the latest well, aptly dubbed Supremus 1, is a worthy rival, said President Felipe Calderon. “We’re finding an oil system that may be the biggest for the company in many, many years — maybe decades,” Calderon said on Friday.
Supremus is offshore the Mexican state of Tamaulipas in 9,513 feet of water. The well was drilled 3,609 feet below the seafloor. At 12,000-plus feet deep, Supremus would be the eighth-deepest well in the world, according to Calderon. Trion was drilled in 8,250 feet of water.
The Supremus may contain proved, probable and possible — 3P — reserves of 75-125 million bbl of oil, according to Pemex.
If early estimates are correct, Mexico’s total Perdido reserves could reach as high as 13 billion boe, Calderon said. The state-run oil company now produces about 2.6 million b/d.
On the U.S. side of the maritime boundary with Mexico in the same area, Royal Dutch Shell plc operates the Perdido Development, a floating production facility with a host spar in Alaminos Canyon Block 857 that began operating in 2010 (see Daily GPI, April 5, 2010).
Perdido was the first producing platform in the emerging Lower Tertiary Trend — and the furthest from shore — and is able to produce annual peak production of more than 200 MMcf/d of natural gas and 100,000 b/d of oil (see Daily GPI, Oct. 27, 2006).
