1 IntroductionThe company is planning the production stage in the field called “Hokchi” through the drilling of 9 new wells and completion for 5 finished wells, in the marine basin of Southern México, with 27 m of water depth and a distance from the block to the Dos Bocas port, Tabasco, of 27 km.

The company is also planning an exploration stage in others fields operated by Hokchi Energy, through the drilling of a well in GoM, in the marine basin of Southeastern México, with 19 m of water depth and a distance from the block to the Coatzacoalcos port of 6 km. The figure 1 shows the location of other areas.
