Grant: ACT ELEGANCY, Project No 271498. Medical CT scans for drainage multiphase flow through carbonate rock cores. The steady state drainage multiphase flow at elevated pressure using nitrogen and DI water, are carried out for three heterogeneous carbonate rocks to characterize the impact of heterogeneity on flow. Core Floods are performed on three carbonate rocks namely, Indiana limestone, Estaillades limestone and Edwards dolomites. Experiments are carried out using medical CT scanner and N2-water fluid system at high pressure. Drainage core floods are carried out by varying nitrogen fractional flow rates from 0 to 1. Residual trapping is obtained at the end of drainage cycle by water flooding of the core. These rocks are from three difference quarries. Indiana carbonate is from Salem Formation located in Indian, USA. Estaillades limestone is from Oppède quarry, France. Edwards dolomite is from Texas, USA. The data set contain medical CT Dry scans, nitrogen scans , water scans and scans at varying fractional flow of nitrogen; 1 readme file; 1 excel file; 27 zip files.

The current database was developed to record Karst Geohazard information acquired as part of its onshore core and commissioned mapping programmes. Information held on the database includes details on stream sinks, sinkholes, natural cavities and associated building damage. The database is being compiled when staff and project funds are available to do the work. The dataset is currently updated on an irregular basis as new karst geohazard information is received from field surveys. Karst geohazard details observed and measured in the field are recorded on a standard proforma or digitally using the BGS•SIGMAmobile tablet computers or in the office via a GSD (Geological Spatial Database) to ensure consistency of information and to allow easy entry into the database. The database currently holds details of karst geohazards in: The limestone areas of the Mendip Hills, Bath, Bristol, Monmouth, Plymouth, Derbyshire Dome,and South Wales (North Crop), North Pennines (Malham to Hawes and Weardale: Rookhope to Cornriggs). The chalk of Southern England (especially in Dorset, and the Salisbury, Winchester, Andover, Basingstoke, Dorchester, Hungerford and Alresford, Worthing, South London (Leatherhead-Croydon-Bromley), Newbury, Maidenhead, Hemel Hempstead, St Albans, Hatfield. Jurassic limestone areas from Grantham to Stamford. Gypsum areas in Yorkshire, Cumbria and Darlington. Salt areas in Cheshire and Stafford (natural and brine extraction-induced sinkholes). The database is eventually intended to hold information on karst geohazards throughout Great Britain and about half of the country is now included.
