Exploring structure and stress from depth to surface in the Wairakei Geothermal Field, New Zealand
(International Geothermal Association, 2016-02-22)
Structures such as fractures and faults have an important role as fluid flow pathways in geothermal fields, as the reservoir rocks hosting geothermal resources can often have little to no intrinsic permeability. As such, ...
Geothermal structural geology in New Zealand: Innovative characterisation and micro-analytical techniques
(International Geothermal Association, 2016-11-23)
Many of New Zealand's geothermal reservoirs are hosted in rocks with low intrinsic permeability. As such, successful development of these resources relies on understanding the role subsurface structures, such as fractures ...
Damaged beyond repair? Characterising the damage zone of a fault late in its interseismic cycle, the Alpine Fault, New Zealand
(Elsevier, 2016-07-25)
X-ray computed tomography (CT) scans of drill-core, recovered from the first phase of the Deep Fault Drilling Project (DFDP-1) through New Zealand's Alpine Fault, provide an excellent opportunity to study the damage zone ...
