To measure the development and success of a public policy on hydrocarbons, it is necessary to go beyond the federal implementation and delve into particular issues at the state level. In the case of Mexico there are four states that are fundamental to the sound and correct development of the industry, these states are: Tamaulipas, Veracruz, Tabasco and Campeche.

These states have witnessed the evolution of the hydrocarbons industry in Mexico since its inception. Because these states have important hydrocarbon formations, their administrations have contributed directly to the adaptation of PEMEX operations in each of the fields they have been. However, with the arrival of new operators and service companies, these states will have to follow and adapt public policies on hydrocarbons in a smarter and faster way in order to attract important investments for them, achievement that will represent and enormous opportunity of economic and social development for them and for the country.
