2 © NERC All rights reserved Web-enabled GIS Now up and running 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 CO 2 migration and Heriot Watt for an MSc thesis.

3 © NERC All rights reserved 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 © NERC All rights reserved 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 © NERC All rights reserved Analytical modelling Joint paper (Andy Chadwick) with Cambridge (Mike Bickle) on analytical modelling of CO 2 flow in the Sleipner plume.

6 © NERC All rights reserved 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 © NERC All rights reserved BGS plans Ongoing discussions to build upon current CO 2 - water-rock investigations (e.g. with Leeds and Cambridge Universities), and explore ways to take them further.

8 © NERC All rights reserved 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 © NERC All rights reserved BGS plans Investigations of fault-controlled CO 2 migration in fine-grained rocks, based on analogues in central Italy. Recently discovered quarry outcrops reveal fractures and faults that are actively allowing volcanic CO 2 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 CO 2 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.
