Web-enabled GIS
• Now up and running
• http://www.bgs.ac.uk/co2/ukco2.html?
• BGS datasets are available to all partners for the project duration.
• Geology of UK north Sea & onshore, seabed sediments
• Esmond Field model has been given to Leeds for reservoir simulation to model fault influences on CO2 migration and Heriot Watt for an MSc thesis.

BGS advice to policy-makers
• April 06: Discussions with Coal Authority (Jonathan Pearce)
• September 06: UKERC Energy in Eastern Europe workshop (Sam Holloway & Jonathan Pearce).
• December 06: Anglo-Italian workshop: Clean Coal Technologies: A UK-Italy perspective towards a successful zero emission strategy (Nick Riley & Jonathan Pearce).
• Advice to the DTI and DEFRA re CCS for negotiations within OSPAR and the London Convention (Sam Holloway).
• April 07: Presentations and discussions on CCS with UK Minister of Transport (Andy Chadwick Sam Holloway).

BGS plans
• Add estimates of storage capacity of North Sea oilfields and gas fields to GIS.
• Will be crude estimates based:
• for oilfields on the storage space vacated by the additional oil that could be recovered by EOR (say 7% of OIIP)
• For gas fields on the storage space vacated by the URR, discounted to take account of water invasion and other factors

BGS plans
• Ongoing discussions to build upon current CO2-water-rock investigations (e.g. with Leeds and Cambridge Universities), and explore ways to take them further.

BGS plans
• Bunter Sandstone study of storage processes: reservoir simulations and reservoir quality study.
• Petrology
• Porosity/permeability from core and logs
• Compare seismic surveys over producing Bunter Sst fields and prospective storage structures re leakage
• Further develop analytical modelling of Sleipner plume and compare with numerical simulations

BGS plans
• Investigations of fault-controlled CO2 migration in fine-grained rocks, based on analogues in central Italy.• Recently discovered quarry outcrops reveal fractures and
faults that are actively allowing volcanic CO2 to migrate to the surface.
• Quarry is thought to be an inactive kaolinite quarry, though history of development is still being researched.
• Outcrops may therefore provide information on CO2 migration through fracture-controlled permeability in fine grained rocks.
• Petrographic and geochemical investigations of fracture controls on permeability will be combined with ongoing fluid geochemistry and structural investigations at University La Sapienza Roma.
