Crude oil has recently languished between $26 and $35 per barrel in volatile trading as oil-exporting nations have tried to negotiate potential production cuts.
Pemex plans to keep its production levels fairly constant by boosting one of its biggest fields, which has seen levels decline, Gonzalez said. As a price taker, Gonzalez doesn't see Mexico as a driving force in the price of oil, he said.

"If the price of oil goes up, we would be very happy," Gonzalez said, commenting on the outcome of rumored OPEC cuts.

"We're optimistic that the energy reform is structural and it will work out in the future," he said.
