this page about Villahermosa:
$this->bbcode_second_pass_quote('', 'V')illahermosa is the axis of Mexico's oil and gas activities. Nearly the totality of oil and more than 90 percent of natural gas is produced within a 200 km radius of the city. Similarly, due its strategic location and accessibility, Villahermosa is an easy drive to or from the seaports that handle 95 percent of Mexico's crude oil exports.
One of the most relevant attribute of the state of Tabasco is that it is covered by water, and the capital, Villahermosa, is no exception. Nearly a third of Mexico's interior water runs through Tabasco and produces an important share of electric power.
Some of the O&G companies with premises in Villahermosa are: Pemex Exploration and Production (South Region, Drilling Unit, Engineering of Strategic Projects); Mexican Petroleum Institute (IMP), Schlumberger, Halliburton, Baker Hughes, Core Lab, Great Wall Drilling Co., Petrotec, Precision Drilling, CGG, among others.
Clearly, O&G exploration and production activities have been the mainstay of Villahermosa economy. This condition is being reinforced by the important set of exploration and production projects that are being developed both, offshore and onshore, in Southeast Mexico. The triplication of Pemex Exploration and Production (PEP) investment budget in Tabasco (from 2001 to 2002) illustrates this point.
80% of Tabasco is under water. I think there's no report on the effect on the oil infrastructure because they haven't been able to assess it. That, and they are busy getting people off rooftops and getting them food and water. IIRC, it was like this with New Orleans, too. It was days before the oil companies were able to fully assess the damage.
