Mexico is in transition towards commercial exploitation of its shale gas, which is being included in two auctions of 24 hydrocarbon blocks, at a time when the country is having difficulty preventing and reducing industrial methane emissions.

Increasing atmospheric release of methane, which is far more polluting than carbon dioxide (CO2) and which is emitted along the entire chain of production, is threatening the climate goals adopted by Mexico within the Paris Agreement which aims to contain global warming.

“Shale gas is the last gas that is left to exploit after reserves that are easier to access have been used up. Its production entails higher economic, environmental and energy costs. It is practically impossible for a shale gas well to be non-polluting,” researcher Luca Ferrari, of the Geosciences Institute at the state National Autonomous University of Mexico (UNAM) told IPS.

The state-run but autonomous National Hydrocarbons Commission (CNH) issued a resolution on Jun. 22 calling for bids for the two auctions of 24 blocks of gas and oil in five basins, located in the north, southeast and south of the country. For the first time, shale gas reserves are included. Bidding will take place on Jul. 12, and total estimated reserves of 335 million barrels are being offered.

By refraining from producing non-conventional fuels (like shale gas) itself, the government is partially opening the energy sector to participation by private enterprise to supply the country’s industrial gas needs.

Mexico’s energy reform, introduced in August 2014, opened up exploitation, refining, distribution and sales of hydrocarbons, as well as electricity generation and sales, to national and foreign private sectors.

In shale gas deposits, hydrocarbon molecules are trapped in sedimentary rocks at great depths. Large quantities of a mixture of water, sand and chemical additives, which are harmful to health and the environment, have to be injected to recover shale gas and oil. The “fracking” technique used to free shale gas and oil leave huge volumes of liquid waste that has to be treated for recycling, as well as methane emissions that are more polluting than CO2, the greenhouse gas responsible for most global warming.
