Shale UK conference report 3
Cuadrilla believes there could be over 330 trillion cubic feet (tcf) of gas in its Lancashire licence area – 50 per cent more than an earlier estimate.
Huw Clarke, the company’s senior geoscientist, made the announcement at the Shale UK conference in London yesterday. He also said the company planned to extract gas from different depths using stacked horizontal wells.
Cuadrilla’s licence area PEDL 165 covers 1,000 square km around Blackpool and the Fylde peninsula. Cuadrilla originally estimated a gas resource of 200 tcf based on information from one well, Huw Clarke told the conference.
Since then, he said the company had drilled two more wells and carried out 3D seismic surveys. “I believe there’s closer to 330 tcf in place just within Cuadrilla;s licence area alone.” He also said “We think more than one level [in the geology] will be productive. We are thinking of [extracting at] stacked levels.
Last summer, the British Geological Survey reported there could be 1,300 tcf in the Bowland basin in north west England.
Cuadrilla is the only company in the UK to have carried out high volume, high pressure hydraulic fracturing. It’s fracking operation at Preese Hall was suspended after an induced earthquake.
