Heterogeneity of structure and stress in the Rotokawa Geothermal Field, New Zealand
(American Geophysical Union (AGU), 2015-02-12)
Geometric characterization of a geothermal reservoir's structures, and their relation to stress field orientation, is vital for resource development. Subsurface structure and stress field orientations of the Rotokawa ...
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 ...
Quantitative geometric description of fracture systems in an andesite lava flow using terrestrial laser scanner data
(Elsevier, 2017-06-03)
Permeability hosted in andesitic lava flows is dominantly controlled by fracture systems, with geometries that are often poorly constrained. This paper explores the fracture system geometry of an andesitic lava flow formed ...
Processing and analysis of high temperature geothermal acoustic borehole image logs in the Taupo Volcanic Zone, New Zealand
(Elsevier, 2014-06-19)
Acoustic borehole televiewer (BHTV) logs provide direct observations of lithology,
structure and in-situ stress in reservoirs, essential for successful well targeting
and field management. Analyses of BHTV logs acquired ...
