We assessed sandstones from the UK Geoenergy Observatories (UKGEOS) site in Glasgow, UK and the Wilmslow Sandstone Formation (WSF) in Cumbria, UK at the pore scale to indicate suitability for further assessment as CCS reservoirs. We measured porosity, permeability and other pore geometry characteristics using digital rock physics techniques on microcomputed tomographic images of core material from each site. We found the Glasgow material to be unsuitable for CCS due to very low porosity (up to 1.65%), whereas the WSF material showed connected porosity up to 26.3% and permeabilities up to 6040\u2005mD. Our results support the presence of a percolation threshold at 10% total porosity, introducing near full connectivity. We found total porosity varies with permeability with an exponent of 3.19. This provides a reason to assume near full connectivity in sedimentary samples showing porosities above this threshold without the need for expensive and time-consuming analyses.<\/jats:p>\n          <jats:p content-type=\"supplementary-material\">\n            <jats:bold>Supplementary material:<\/jats:bold>\n            Information about the boreholes sampled in this study, additional well logs of boreholes and a summary of the supporting data plotted throughout this article from literature are available at\n            <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" specific-use=\"dataset is-supplemented-by\" xlink:href=\"https:\/\/doi.org\/10.6084\/m9.figshare.c.5260074\">https:\/\/doi.org\/10.6084\/m9.figshare.c.5260074<\/jats:ext-link>\n          <\/jats:p>\n          <jats:p content-type=\"thematic-collection\">\n            <jats:bold>Thematic collection:<\/jats:bold>\n            This article is part of the Geoscience for CO\n            <jats:sub>2<\/jats:sub>\n            storage collection available at:\n            <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.lyellcollection.org\/cc\/geoscience-for-co2-storage\">https:\/\/www.lyellcollection.org\/cc\/geoscience-for-co2-storage<\/jats:ext-link>\n          <\/jats:p>","DOI":"10.1144\/petgeo2020-092","type":"journal-article","created":{"date-parts":[[2021,1,13]],"date-time":"2021-01-13T12:35:23Z","timestamp":1610541323000},"update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Pore-scale assessment of subsurface carbon storage potential: implications for the UK Geoenergy Observatories project"],"prefix":"10.1144","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5724-0695","authenticated-orcid":false,"given":"Ryan L.","family":"Payton","sequence":"first","affiliation":[{"name":"Department of Earth Sciences, Royal Holloway University of London, Egham\u00a0Hill,\u00a0Egham, Surrey TW20 0EX, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7969-0021","authenticated-orcid":false,"given":"Mark","family":"Fellgett","sequence":"additional","affiliation":[{"name":"British Geological Survey, Nicker Hill, Keyworth, Nottingham NG12 5GG, UK"}]},{"given":"Brett L.","family":"Clark","sequence":"additional","affiliation":[{"name":"Imaging and Analysis Centre, Natural History Museum, Cromwell Road, London SW16 5EQ, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2482-0081","authenticated-orcid":false,"given":"Domenico","family":"Chiarella","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Royal Holloway University of London, Egham\u00a0Hill,\u00a0Egham, Surrey TW20 0EX, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4979-588X","authenticated-orcid":false,"given":"Andrew","family":"Kingdon","sequence":"additional","affiliation":[{"name":"British Geological Survey, Nicker Hill, Keyworth, Nottingham NG12 5GG, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2629-1729","authenticated-orcid":false,"given":"Saswata","family":"Hier-Majumder","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Royal Holloway University of London, Egham\u00a0Hill,\u00a0Egham, Surrey TW20 0EX, UK"},{"name":"Advanced Scientific Computing and Research, US Department of Energy, 19901 Germantown Road, Germantown, MD 20874, USA"},{"name":"AAAS Science and Technology Policy Fellow"}]}],"member":"1881","published-online":{"date-parts":[[2021,3,19]]},"reference":[{"key":"e_1_3_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijggc.2015.01.007"},{"key":"e_1_3_5_5_1","doi-asserted-by":"crossref","unstructured":"Bloomfield J.P.
