(Reuters) - Success for shale gas extraction in Europe will
hinge on developing more efficient techniques and a more
targeted approach to fracking, Andrew Gould, chairman of UK gas
producer BG Group PLC, said on Thursday.  Until recently, shale
gas extracting firms have used a "blitzing technique" whereby
they frack as much as they can in the hope of opening gas to the
well, Gould told delegates at a resource scarcity conference in
Oxford.  Hydraulic fracturing, or fracking, involves extracting
natural gas trapped in tight layered rock formations by
injecting high-pressure water, sand and chemicals.  "Everyone is
working on this and eventually they will identify the most
productive parts of shale and only frack where they know they
going to produce (gas)," he sai
