Mexico's shale revolution might have to wait

The future of Mexico's first auction of blocks of "shale" oil and gas resources under the energy reform is in doubt because of a wave of kidnappings and murders in the northern stated of Tamaulipas.

Mexico has the same geology as the areas in the US that have launched a high profitable "shale revolution" that has made billionaires of producers there.

But Tamaulipas is immersed in a savage war between gangs of organized crime that smuggle drugs and people to the US. And now they are fighting over the illegal trade in fuel.
