A new feature of Round 3.1 is the inclusion of four "exploration-extraction clusters," CNH said. These blocks include discovered fields that were not awarded in Round 2.1.
These blocks will give access to areas with exploration potential as well discovered fields ready for development, CNH has said previously.
CNH will auction 14 fields with a total area of 8,400 sq km in the Burgos region in the state of Tamaulipas' offshore. This is the first time Mexico would offer blocks in this region.
These have an average area of 602 sq km, water depths up to 590 meters and prospective resources of 56% wet gas and 44% light oil. Expected resources for four blocks is wet gas and for 10 blocks is light oil.
CNH will offer 13 blocks in the Tampico-Misantla-Veracruz, or TMV, basin with a total area close to 12,500 sq km. These blocks have an average area of 960 sq km and their water depths are up to 860 meters.
