4. Geothermal setting

5. Shallow geothermal exploitation

6. Deep geothermal exploration

7. GT Energy – Newcastle, Dublin

9. NE/SW fault trend

10. Extensive folding and faulting – Caledonian Orogeny

15. Shallow Geothermal Resource Map Geothermal Resource Map of Ireland (CSA, SEI 2004):

18. Lewis Gluckman Gallery (Arup, 2006)

22. Abundance of deep penetrating more recent faults and fractures in the South of Ireland results continuous leaking of heat to the surface – poor geothermal gradients

25. Newcastle Deep Borehole Project

28. Geothermal ENERGY ltd. (Phase 2 Deep Geothermal Exploration Report. SLR, 2008)

30. Temperature measured at 1,400m : 46.2oC

31. Artesian flows at both NGE1 and NGE2

32. Geothermal fluids associated with fracturing in deep Carboniferous limestone and sandstone

33. Younger shale rich limestone above with poor permeability act as containment (up to 800m thick in places)

36. Considerable fracturing at depth associated with BNF

37. Favourable groundwater water pressure heads – artesian flow

38. Deep seismic survey over next few months followed by proposed 3000m well to N of NGE1 and NGE2

39. Currently tendering for drilling contract.

43. Legislative barriers – potential to use mining legislation

44. Economic crisis – €20B cash deficit (July 09) Unemployment (July 2009) 12.2% (~400,000) Electricity Generation from geothermal– dependant on advances in Binary and EGS

45. One for the engineers.... Calvin & Hobbes. Waterson THANK YOUFOR YOUR ATTENTION
