Production and exports of crude oil at Mexican state oil company Petroleos Mexicanos, or Pemex, increased in October, the firm said on Friday.Crude output rose by 9.9 percent from the previous month to 1.902 million barrels per day (bpd) after suffering a sharp drop in September, according to Pemex data published online. Exports increased by 15.8 percent to 1.342 million bpd, the highest total since September 2016. Pemex’s crude output has been falling steadily since 2004, although an energy reform now underway is bringing billions of dollars worth of fresh investment to the industry. Still, the results of that reform are expected to take years to have a sizeable impact on output.
