PESA ACT/NSW September Technical Talk
Guest Speaker(s): Dave Bennett
Dave has more than 40 years’ experience in oil and gas exploration. Following a PhD in geomagnetic depth sounding in the early 70’s he worked on a variety of electrical conductivity studies of the earth’s crust, including in geothermal exploration; so this talk is a return to his academic roots. He is presently a director of Devil Resources but is still actively involved in petroleum exploration in New Zealand and Australia.
Hot Rocks and Hydrogen : the Devil’s Brew
NE Tasmania has a thin crust and shallow Curie Point Depth, and is a geologically distinct terrane to the rest of Tasmania. High heat flow values and slow mid-upper crust Vp values support regional and detailed magnetotelluric surveys which indicate shallow electrical conductivity anomalies similar to those observed beneath geothermal fields in NZ and elsewhere worldwide. Devil Resources has modelled existing data to define a hot zone at economically exploitable depth. Other potential zones are identified nearby. Devil is also investigating the potential for natural hydrogen west of the Tamar, where a set of ultramafic thrusts are identified. The Devil licences are centred on Bell Bay, where a deep water port and manufacturing zone provide a good basis for viable development. Electricity demand in Tasmania is strong and expanding.
