  1. Geological Storage Theme BGS progress

  2. 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.

  3. Fluid-rock interactions • BGS support (Chris Rochelle) of studies at Leeds on fluid rock experiments • Provision of petrographic specimens and materials from US analogues (Jonathan Pearce) to Edinburgh

  4. 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).

  5. Analytical modelling • Joint paper (Andy Chadwick) with Cambridge (Mike Bickle) on analytical modelling of CO2 flow in the Sleipner plume.

  6. 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

  7. 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.

  8. 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

  9. 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.
