Mexico's proven oil and gas reserves dropped 21.3 percent in 2015, the oil regulator said on Thursday, as the state-run oil company, Pemex, cut back on investment because of plunging crude prices.
Proven reserves, known as 1P, fell to 10.242 billion barrels of oil equivalent, or boe, as of Jan. 1, down from just over 13 billion the prior year, according to the National Hydrocarbons Commission, or CNH.
The new estimate for so-called 1P certified reserves was set on Jan. 1, 2016, and covered oil and gas fields believed to have a 90 percent chance . . .
