Misión was one of five blocks awarded under Mexico's first round of bidding for Multiple Service Contracts (MSC) in 2003. It is located in the onshore gas prone Burgos basin. A Tecpetrol led group won the Misión contract with a discount of only 1% the work units proposed by Pemex. The allowed cost recovery in the contract is up to US$1 billion. This figure is the maximum potential investment in the block over the 15 year contract period.
