The spreadsheet gathers the data collected during an experiment conducted on a Utsira Sand formation core sample to complements and constrains existing geophysical monitoring surveys at Sleipner and, more generally, improves the understanding of shallow weakly-cemented sand reservoirs. The tests were conducted in the rock physics laboratory at the National Oceanography Centre, Southampton, during 2016, as part of the DiSECCS project with funding from the United Kingdom’s Engineering and Physical Sciences Research Council (EPSRC grant EP/K035878/1) and the Natural Environment Research Council (NERC). The experiment was a steady state brine-CO2 flow-through test to simultaneously evaluate ultrasonic waves, electrical resistivity (converted into pore fluid distribution) and mechanical indicators during CO2 geosequestration in shallow weakly-cemented reservoirs. The confining and pore pressure conditions were similar to those estimated for Sleipner (North Sea – like storage reservoirs), but simulating inflation/depletion cyclic scenarios for increasing brine:CO2 fractional flow rates. The data include primary ultrasonic wave velocities and attenuation factors, axial and radial strains, and electrical resistivity. Also, we provide a velocity-saturation relationship of practical importance to CO2 plume monitoring, obtained from the inversion of ultrasonic velocity and attenuation data and extrapolation of results to field-scale seismic-frequencies using a new rock physics theory. The dataset is linked to this publication: http://www.sciencedirect.com/science/article/pii/S1750583617306370.

Collections of Aerial Photographs purchased or obtained by BGS and its precursors as part of its surveying activities. Data covers mainly Great Britain or areas where BGS has worked overseas and dates from the 1940's. The collection is incomplete and there are copyright and other constraints on its use.

Collection of reports and general hydrogeological/geological information held in box files by country, almost exclusely by Jeff Davies.

[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13480158] This dataset is an archive of original data for the geophysical logging of boreholes drilled by the National Coal Board (NCB) and its successor, British Coal Corporation (BCC). Data coverage is UK wide and dates from the 1970's to the privatisation of the coal mining industry, in 1994. The dataset includes approximately 2000 field data recording tapes and processed data tapes. The processed data tapes are at various stages of processing and consist of edited data and computed (CSU) data (not available for all boreholes). The data are kept as archive copies. The data are owned by the Coal Authority (CA), as successor to the NCB and BCC, BGS being the custodian under an agreement with the Coal Authority. No full catalogue or index available yet.

Data include geological logs and charts; letters, minutes & memos; notes; externally written reports; Internal reports; Research Reports; annotated publications, records and reports; and other miscellaneous documentation. Although some of the data go back to the first half of the 20th century (and rarely earlier), the bulk of the data refer to work carried out since about 1960. The data are filed under four subheadings: i. 1:50K sheet files (data relating to BGS mapping projects) for England & Wales, Scotland and Northern Ireland. ii. Offshore sheet files (data relating to BGS mapping projects) for the UK continental shelf and North Atlantic. iii. Offshore Quadrants (data relating to the hydrocarbons industry) (confidential). iv. Foreign biostratigraphy (in part confidential). v. General Palaeontology, Biostratigraphy & Taxonomy.

EPSRC grant EP/L012227/1: Development of Unified Experimental and Theoretical Approach to Predict Reactive Transport in Subsurface Porous Media. The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of Bentheimer sandstone and Estaillades carbonate. The critical Reynolds number indicating the cessation of the creeping Darcy flow regime in Estaillades carbonate is two orders of magnitude smaller than in Bentheimer sandstone, and is three orders of magnitude smaller than in the beadpack. Also available at https://www.digitalrocksportal.org/projects/11, DOI:10.17612/P77P49. Further details can be found in Bagus P. Muljadi, Martin J. Blunt, Ali Q. Raeini, Branko Bijeljic. The impact of porous media heterogeneity on non-Darcy flow behaviour from pore-scale simulation. Advances in Water Resources. 2015. http://dx.doi.org/10.1016/j.advwatres.2015.05.019.

This document data set contains original prints, on paper, sepia or film, of seismic reflection survey location (navigation) maps. These provide the location data for the seismic sections of the Original Seismic Sections (ORIGSEISECS) and Copy Seismic Sections (COPYSEISECS) datasets. Almost all data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS, for academic research. All maps are digitised upon receipt (see LOCSEC database) and then archived in this data set. (Copies used to be used for interpretation purposes but this is no longer the case.) Documents stored rolled in tubes. Approx 800 maps.

Oracle index to records of some 3500 waste sites in England and Wales identified by BGS as part of a survey carried out on behalf of the Departement of the Environment in 1973. The index has been corrected and updated to a limited extent, but the data itself has not been changed. The data was collected in 1972 and the information reflects the knowledge at that time. It does not reflect current interpretation. Not all authorities made returns and there are not records for all of the sites listed. However, the data is an invaluable source of information about pre-1974 sites. Information includes site name, location and risks to aquifers. It should be noted that the assessments were carried out when the data was collected and may not reflect current interpretation.

Registers of microfossil analyses carried out by FW Anderson in London mainly during the 1950s and 1960s, but includes older collections,notably those of Davis (1935) and Burrows (1948). Specimens recorded are mainly ostracods, but include some foraminifera and some charophytes and holothurians. Sample number, locality/borehole, specimen identifications, remarks, cross referencing to the SAM and other data sets are given. The set is arranged: MIK(M) 1-4483 in 41 volumes on Mesozoic (predominantly) ostracods MIK(T) 1-1590 in 11 volumes, Tertiary foraminifera MIK( C) 1-400 in 5 volumes, Carboniferous ostracods MIK (J) 1-1219 in 8 volumes Jurassic microfossils (few identifications) MIK(K) 1-677 in 7 volumes Cretaceous microfossils (identifications patchy) MIK(J)F, MIK(K)F and MIK(T)F are small foreign collections.

This dataset is an index of the Survey Collection of fossils for Scotland and Northern England. It is the digital equivalent of the analogue (card) index. The latter contains some 31k records, c.70% of which has been transcribed. The continually growing Survey Collection comprises about 450k samples (including nearly 30k specimens from the John Smith Collection) which are individually registered in c.150 leather bound volumes. The Oracle relational database BGS_FOSSLOC is a first step in ascertaining what registered fossil materials exist for certain areas, who collected them and when, their geographical and stratigraphical details, the type of collection (whether from boreholes or exposures), and any covering technical reports. It is also a pathway to an extensive and unique collection of paper graphic logs, some 18k of which record annotated information on fossil occurrences and assemblages at certain stratigraphical levels (particularly in the Carboniferous) in Scotland and Northern England.
