Critique of environm ental statem ent in the context of relevant geology and hydrogeology David Smythe Emeritus Professor of Geophysics, University of Glasgow KEEP Kirdford and Wisborough ‘Green’ 1 No DRILLING

2 Geology and hydrogeology The Application is: • Incomplete • Incompetent • Disingenuous KEEP Kirdford and Wisborough ‘Green’ 2 No DRILLING

3 Geology and hydrogeology Incomplete: • Insufficient seismic data • Selection of locality remains unexplained: “Further clarification is sought with regard to how the primary and secondary search areas were defined, in particular, the extent and nature of geological data used” County Planning Department letter 3 December 2013 KEEP Kirdford and Wisborough ‘Green’ 3 No DRILLING

Seismic 4 Applicant’s geological profiles search area: • Not explained • No data • No rational basis • Non-geological criteria? Primary search area 2 km x 3 km Secondary search area KEEP Kirdford and Wisborough ‘Green’ 4 No DRILLING

5 Kim m eridge Clay Search area for unconventional oil  - 6 3 % of the licence area PEDL2 3 4 licence Ellipses – Celtique’s search areas   Limit of maximum  maturity coincident with  3000’ (3500’) minimum depth (to top). Data from BGS Weald report. KEEP Kirdford and Wisborough ‘Green’ 5 No DRILLING

6 Geology and hydrogeology The Application is: • Incompetent [ Original application full of errors - some corrected later] KEEP Kirdford and Wisborough ‘Green’ 6 No DRILLING

7 Geology and hydrogeology • Incompetent - example W ELL Base of Weald Clay Celtique Environmental Statement fig. 11.4 Geological cross-section is 80 m too deep KEEP Kirdford and Wisborough ‘Green’ 7 No DRILLING

8 Geology and hydrogeology Disingenuous: Targets are unconventional KEEP Kirdford and Wisborough ‘Green’ 8 No DRILLING

9 Geology and hydrogeology The Application is for unconventional : “On our Central Weald Licences (PEDLs 231, 234 and 243) we currently have an obligation to drill one well on each licence… the unconventional prospectivity we have defined at … levels are all laterally extensive. … Within our licence area we will be forced to relinquish an unconventional trend proven by drilling, under the 50% area relinquishment rule.” [Celtique Energie letter to DECC, 15 December 2011] KEEP Kirdford and Wisborough ‘Green’ 9 No DRILLING

10 Geology and hydrogeology UK shale basins – basic facts: The Weald Basin: • 400 times as many faults as US basins • Different origin from US basins Risky to groundwater and surface: Faults can be a fast track to the surface KEEP Kirdford and Wisborough ‘Green’ 10 No DRILLING

11 Geology and hydrogeology The Application has only two possible outcomes: • Relinquishment of PEDL234 OR • Unconventional development KEEP Kirdford and Wisborough ‘Green’ 11 No DRILLING

12 Geology and hydrogeology Conclusion - the Application is: • Incomplete • Incompetent • Disingenuous Full details have been provided in my submission of June 2014 (53 pages + 19 figures) Therefore I recommend REJECTI ON KEEP Kirdford and Wisborough ‘Green’ 12 END No DRILLING
