The Bowland Basin is a key part of the Pennine Carboniferous Petroleum system is calculated to have significant shale gas resource potential with over 200 TCF OGIP The basin is one of a number of linked, Lower Carboniferous trans-tensional basins characterized by thick accumulations of hemi-pelagic calcareous mudstones and related facies. In Bowland there is up to 2000m of gas saturated section comprising the Hodder, Lower Bowland and Upper Bowland Shale Formations. This paper will describe the results of recent exploration activity by Cuadrilla Resources Ltd between 2010 and 2012. These include the gas discovery well at Preese Hall-1 and the wells at Grange Hill-1 and Becconsall-1. The Bowland basin epitomizes the challenges faced in developing European Shale gas. These include the strategies needed for developing thick geological sections using a relatively small surface footprint in a socially responsible and acceptable manner. The Cuadrilla strategy for this is centred on multilateral well pads and the geological workflows surrounding the associated technology. This includes detailed 3D understanding of the subsurface in terms of sedimentary architecture and the location of the most productive zones, the regional and local structure and the stress distribution in the subsurface, especially the location of critically stressed areas. In the presentation Cuadrilla will describe it’s progress to date and outline strategies planned to unlock the resource potential of the Bowland Basin.
