Processing and analysis of high temperature geothermal acoustic borehole image logs in the Taupo Volcanic Zone, New Zealand
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 ...
Calcite sealing in a fractured geothermal reservoir: Insights from combined EBSD and chemistry mapping
Fractures play an important role as fluid flow pathways in geothermal resources hosted in indurated greywacke basement of the Taupo Volcanic Zone, New Zealand, including the Kawerau Geothermal Field. Over time, the ...
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 ...
