A venture including Texas shale explorer Heyco Energy Group won an extension of its permit to search for oil and gas in an area of northern Spain that the industry designated as one of the richest to be fracked.

The original 2006 permit ran out in August before the government ruled on whether drilling was compatible with environmental laws, according to a May 14 resolution that wasn’t published until today. The venture’s biggest partner is Shesa, an energy company of the Basque regional government.

Spain’s central government is trying to revive oil and gas drilling, and considering shale ventures that use hydraulic fracturing, or fracking, after a several-decade lull in exploration. It’s fighting in the Supreme Court to overturn bans on fracking imposed by several regional governments.

The extension of the Angosto-1 permit, effective tomorrow, allows the venture to drill exploration wells through June 2016 provided it wins environmental clearance. The rural site is in a hilly area, rich in rivers, stretching through the Basque, Cantabria and Castilla & Leon regions.

Spain currently has no exploration or production using fracking and horizontal drilling, techniques that have delivered an energy bonanza in the U.S.
