  • This presentation on the UKCCSRC Call 1 project, Tractable Equation of State for CO2 Mixtures, was presented at the Cranfield Biannual, 22.04.15. Grant number: UKCCSRC-C1-22.

  • This poster on the UKCCSRC Call 1 project Fault Seal Controls on Aquifer CO2 Storage Capacity was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C1-14. Structural traps for storage of supercritical CO2 will commonly rely on a component of fault seal. Faults are among the most important natural potential migration pathways for buoyant fluids stored in reservoir rocks. Failure of storage integrity may occur either by mechanical failure or by flow across faults due to geometric juxtaposition of the reservoir against similarly permeable rocks and/or lack of a low permeability fault gouge. This project aimed to reduce uncertainty relating to the sealing capacity of faults affecting prospective North Sea saline aquifers, by: • Studying the controls on fault seal capability in naturally-occurring fault-bound CO2 accumulations (Fizzy and Oak), • Assessing the geomechanical stability of faults affecting an important saline aquifer offshore UK (Captain Sandstone), • Investigating the characteristics of apparently hydraulically-conductive faults in the North Sea (Netherlands).

  • This project will tackle one of the key technical challenges facing the development of commercially viable CO2 transport networks: modelling the phase behaviour of impure carbon dioxide, under the conditions typically found in carbon capture from power stations, and in high-pressure (liquid phase) and low-pressure (gas phase) pipelines. Models for phase behaviour are known as equations of state (EoS). EoS vary in their mathematical form, accuracy, region of validity and computational complexity. Because different applications have different requirements, there is no single EoS that is ideal for all applications. This project will use cutting-edge computer algorithms to automatically reparameterise EoS for CCS modelling. This flexible technique will allow a user to specify their requirements and re-derive model parameters matched to their needs. Our algorithms will directly produce functional forms for EoS from experimental data, thus fully automating the derivation of EoS. This will enable users to rapidly produce bespoke EoS that are tailored to their particular application, and will enable these models to continually evolve as new measurements become available, ensuring that experimental advances are rapidly converted into improved CCS modelling and, ultimately, better performance and efficiency of real CCS processes. Grant number: UKCCSRC-C1-22.

  • The Quaternary deposits thickness dataset is a digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which shows the thickness of the deposits over bedrock in three categories: <5m, 5-50m, and >50m Quaternary cover. These depth bands were picked because they represent the horizons that have impact on offshore infrastructure deployment. The map is derived from (unpublished) BGS 1:1000000 scale Quaternary digital geological mapping. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The data are held by the BGS as an ESRI ArcGIS Shapefile.

  • Output from the FAMOUS General Circulation Model presented in the study by Dentith et al. (2018) "Ocean circulation drifts in multi-millennial climate simulations: the role of salinity corrections and climate feedbacks". The following ocean variables are included at model resolution (2.5 ° x 3.75 °): salinity, meridional overturning streamfunction, potential temperature, mixed layer depth, and barotropic streamfunction. Precipitation, evaporation and sea ice concentration data are also included at atmospheric resolution (5 ° x 7.5 °). All data has been processed into netCDF timeseries.
