The seismic survey consists of three lines totalling 11km; two running roughly N-S either side fo DTC's site and the third running E-W.

Cuttings collected during the drilling of the high pressure well were analysed by Aberdeen University. A full suite of electric lofs was run in the high pressure well, consisting of BGT - GR, LDL - CNL - NGS, Pl - AS - GR, FMS - NGS, VSP.

Interpretation of the various data shows a few metres of Old Red sandstone overlaying a thick sequence of Dalradian metasediments dipping at 10 to 20 degrees to the NE. These are intruded by granitic veins and sheets with little evidence of post intrusion faulting. There are several 'shatter zones' where the rock is naturally shattered into fist-sized and smaller fragments. The rock is generally hard and abrasive. Sonic travel times are typically 50 to 60 microseconds per foot for most depths logged. Cores taken near surface (40m) indicate compressive strengths of the order of 130 MPa, but correlation between core strength and acoustic data suggests strengths exceeding 200 MPa at depths of 1500m.

Further information on the seismic surveys and electric logging is available on request.
