Mexican state oil company Pemex said on Dec. 6 it has discovered a deposit in southeastern Mexico that could yield 500 million barrels of crude, calling it the largest such finding in more than 30 years.
Pemex said it first discovered the field in Tabasco state in May, before beginning studies to evaluate its viability. The site, called Quesqui, is a so-called 3P reserve, made up of deposits considered proven, probable and possible.
"With the analysis of information provided by this well and seismic data in the area, we can confirm today the existence of a giant deposit equivalent to 500 million barrels of crude oil in a 3P reserve," Pemex Chief Executive Octavio Romero Oropeza said in a statement.
He added that Pemex aimed to extract 69,000 barrels per day (bbl/d) from the site by next year, and reach 110,000 bbl/d by 2021.
Oil firms Equinor and Rosneft expect to extract some 250 million barrels of oil and 23 billion cubic meters of gas during the first part of the development of the Severo-Komsomolskoye oilfield in Russia, Equinor said on Dec. 23.
Repsol will still hold a 51% stake in the block after the deal.
Chevron said on Dec. 24 it expects Saudi-Kuwaiti Neutral Zone's Wafra oilfield to return to full production within 12 months.
