Basin transection in the Vale of Pickering, North Yorkshire: implications for energy resources and geological storage

Year: 2025
Type: conference-paper
Abstract: The Vale of Pickering (VoP) in North Yorkshire has played host to several small gas discoveries that have come to the end of their production life. Now that the fields have ceased production, there is an opportunity to repurpose them and their infrastructure for the energy transition. Using an extensive, well-constrained seismic dataset, mapping of the VoP has revealed the presence of a NNE–SSW-striking Carboniferous basin precursor, the (newly defined) Slingsby Trough, containing Visean (syn-rift) organic shales that source the gas reservoirs and Namurian sandstones (post-rift) that form secondary reservoirs. Structural inversion of the half graben because of foreland deformation during the Variscan orogeny led to uplift, folding and peneplanation by the Base Permian Unconformity. The area was subsequently overlain by Upper Permian Zechstein Group carbonates and evaporites deposited on the margins of the Anglo-Polish Basin, creating the main reservoir–seal pair and a local petroleum system. Mesozoic faults striking ESE–WNW transected the area and created three-way, fault-bound footwall closures, forming a hydrocarbon ‘sweet-spot’ in the VoP through the coalescence of traps, a reservoir–seal pair and a mature source rock. This study improves our understanding of the various geological conditions that lead to its hydrocarbon prospectivity, explains why interest was shown in its unconventional resource potential, and provides a basis for evaluating the feasibility of re-imagining these fields as viable onshore storage and geothermal sites to aid the decarbonization of NE England.
