Mexico's Energy Minister Pedro Joaquin Coldwell (L) chats with Pemex Chief Executive Emilio Lozoya during the presentation of the so-called 'Round Zero' allocation in Mexico City August 13, 2014. Mexico will assign oil and gas exploration and production contracts to foreign and private companies between next May and September under a major sector overhaul, prioritizing areas that boost output quickly and leaving trickier deep water for later, the country's energy regulator said on Wednesday. Mexico's energy ministry on Wednesday assigned 83 percent of the country's probable and possible reserves to Pemex under the historic energy overhaul, which breaks the state's energy monopoly and seeks to lure billions of dollars in investment.
