Mexico’s state-owned petroleum firm Pemex has cancelled migrating contracts for the Magallanes, Panuco, Pitepec, Altamira, Amatitlan, Humapa and Miahuapan blocks, according to board minutes, as part of a plan to go it alone. In December 2017, Petrofac's integrated exploration and production (E&P) contract for the Santuario block was switched to a production-sharing contract. Production has since increased by 70%. Petrofac expected migration of its contracts for the Magallanes and Arenque blocks. However, President Andres Manuel Lopez Obrador's government has stopped all farm-outs, scheduled upstream auctions and migrations, closing off options for private investment in Mexico’s energy sector.
