Cuadrilla Resources – Fylde

After a series of public meetings about the exploration for potential shale gas resources in the underlying West Lancashire Basin (also known as the Bowland Basin), we were commissioned by Cuadrilla Resources and their PR consultants PPS to carry out a review of the potential causes of geological hazards that might lead to subsidence and ground deformation. This took place in the light of media coverage of hydraulic fracturing (known as 'fracking') and concerns expressed by environmental groups.
 
We collated and assessed publicly available information published by the British Geological Survey, supplemented with other archive data and experiences. This gave us the basis for a conceptual assessment of subsidence and ground deformation associated with coal and metal mining, swelling and shrinkage of soils, landslides, dissolution of evaporites in the overlying Triassic strata, excessive and differential settlement of soils, soil collapse, running sand conditions, induced seismicity from engineering and drilling, tectonic (natural) background seismic events and manmade causes of subsidence.
 
Our report provided a more informed understanding of geological and geomorphological process in West Lancashire and the potential causes of seismicity, subsidence and ground deformation associated with shale gas exploration and operation.
