Spain Shale Gas Reserves Estimated to Equal 39 Years of Demand

Spain, a country that’s yet to produce its first shale gas, probably has enough resources of the fuel to satisfy domestic demand for at least 39 years, according to the nation’s Council of Mining Engineers.

The estimated reserves of natural gas trapped in shale rock are about 50 trillion cubic feet, Fernando Pendas, a water and oil geology professor at University of Oviedo, said today at a briefing in Madrid to present the council’s findings. The estimate could double once exploration studies are finalized and more is discovered through breaking open rock using hydraulic fracturing, knowns as fracking.
