“…The paper by Riley et al (2016) describes some of the different technologies being used to enhance how the industry characterizes the uncertainties associated with different shale plays together with the associated exploration-related risks. It is becoming clear that integrated multidisciplinary approaches offer the best chance of success in these onshore plays where combining the various technologies and techniques used in conventional resource assessment with high-resolution mudrock-focused techniques can help better characterize and predict the location and distribution of highquality resources (sweet spots).…”

chosen to reflect the aim of enabling those Earth scientists and subsurface practitioners currently working on hydrocarbon resources across NW Europe to make optimal use of the considerable past investments in the largely offshore facilities, as well as the scientific understanding and knowledge gained. The ultimate focus is to maximize the safe and effective use of the investments to create and deliver resources for a low-cost energyhungry society. A modest number of papers also specifically looked forward to the re-purposing of oil and gas facilities for a lowcarbon-energy future. The conference was attended by 530 delegates. These included postgraduate students from the new Doctoral Training Scheme in Petroleum Geology based at Herriot Watt, as well as seven prizewinning Masters students whose attendance was generously sponsored by the late Dave Roberts' widow, Robin. Two Best Paper awards were sponsored by BP and Shell, and named (with the kind permission of their respective families) in honour of the late Dave Roberts (BP) and Peter Ziegler (Shell). These were awarded to: † Nick Schofield of Aberdeen University for 'Intrusive and extrusive sequences and their interactions with hydrocarbon systems-a key geoscience challenge?'; † Fred Hughes, of Third Energy for 'North Yorkshire's sleeping giant'. Conference and proceedings structure The conference was originally organized around a series of themes covering the full range of the Upstream Oil and Gas Value Chain, and spanning all of the main and less well-known plays and pay fairways. Sessions included, for example, Key geoscience challenges, Key field and fairways, Key geophysics challenges, and Petroleum systems and fairways. Of the 62 oral presenters who gave presentations, 32 authors actually submitted papers. Seven of the poster presenters subsequently stepped up to submit full written papers. Reflecting this, the structure of this volume reflects the Table 1. Core workshop displays Stratigraphic age Reservoir/field Region Eocene Catcher 28/9a-6 28/9a-2

We conducted a high-resolution multi-disciplinary analysis of two core sections in the borehole Ellesmere Port-1, Cheshire, UK. Biostratigraphic analysis indicates the core sections are Kinderscoutian and late Arnsbergian-Chokerian in age, respectively. Both cores are assigned to the Bowland Shale Formation (Holywell Shale). Coupled core scan and discrete geochemical analysis enables interpretation of syngenetic processes at a high stratigraphic resolution. Both cores exhibit the classic cyclicity of limestones, calcareous to non-calcareous mudstones and siltstones, interpreted to represent sediment deposition during fourth-order sea level fluctuation. Machine learning of the well log data coupled to the core scan data enabled prediction of the key lithofacies through the entire Bowland Shale interval in Ellesmere Port-1. The machine predictions show the Bowland Shale is interfingered with three turbiditic leaves of the Cefn-y-fedw Sandstone Formation and contains at least 12 complete fourth-order cycles. The Bowland Shale exhibits high radiogenic heat productivity (RHP) in comparison to other sedimentary rocks, due primarily to relative enrichment in U under intermittently euxinic conditions. Thermal modelling, however, shows Bowland Shale RHP contributes a negligible source of additional heat at the scale of 100s m. Supplementary material at https://doi.org/10.6084/m9.figshare.c.6911105

This volume showcases recent geological, geophysical, and geochemical research on the Carboniferous Bowland Shale Formation, a classic Palaeozoic black shale unit. The Bowland Shale spans ca. 16 Myrs from the upper Visean to mid-Bashkirian, and is perhaps the most important and controversial black shale unit in the UK. The volume focuses on the key Carboniferous basins in the Midlands, northern England, and North Wales. The main basins assessed in the volume are the Craven Basin, including the Bowland sub-basin, the Blacon Basin, the Edale Basin, the Widmerpool Gulf and the Gainsborough Trough. The Bowland Shale and equivalent units are described and interpreted in terms of sedimentary, geochemical, and physical properties and processes, basin-forming events, hydrocarbon prospectivity, mineralization, and heat and fluid flow in the subsurface.
