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.

We are grateful to SLB (Petrel) and ESRI (ArcGIS Pro) for providing academic software licences to the University of Aberdeen, which were used in the analysis and visualization of geological and geophysical data. We acknowledge the UK Onshore Geophysical Library (UKOGL) administered under contract by Lynx Information Systems Ltd, for access to the seismic data volumes. We thank Malcolm Butler for his support in providing seismic and well data through UKOGL. IHS Markit, now S&P Global, are thanked for the provision of, and permission to publish, examples from their onshore well database. Valuable technical discussions with Thomas Houghton are gratefully acknowledged. This study builds upon and continues the work undertaken by Laura-Jane Fyfe in Fyfe and Underhill (2023a, b). The British Geological Society is thanked for use of online open-access datasets such as the Geology of Britain viewer, onshore GeoIndex and borehole material database. The authors would also like to thank reviewers Stephen Corfield and Douglas Paton for their insightful comments and feedback which has strengthened the contents of this paper.Data availability
The data used within this study are from open access sources unless otherwise stated. Open access source material included in this project has been obtained from the British Geological Society and the UK Onshore Geophysical Library (https://ukogl.org.uk). This study contains public sector information, licensed under the Open Government Licence v3.0, and also contains British Geological Survey materials © UKRI 2024. Datasets for 12 onshore wells, which are not in the public domain, were purchased from IHS Markit, now S&P Global (https://my.ihs.com/Energy to support this research.
