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 ...
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 ...
Volcanic texture identification and influence on permeability using a borehole resistivity image log in the Whakamaru Group Ignimbrite, Wairakei Geothermal Field, New Zealand
(Workshop on Geothermal Reservoir Engineering, 2018-02-12)
Discerning the contributions to fluid flow in a geothermal reservoir from intrinsic and structural permeability components is an
important, yet difficult task. High-quality, resistivity borehole image log data (Formation ...
Discussion between a reservoir engineer and a geologist: permeability identification from completion test data and borehole image logs integration
(39th New Zealand Geothermal Workshop, 2017-11-22)
The location of permeable zones, and preliminary quantification of a geothermal well’s production or injection capacity are routinely interpreted from well pressure, temperature, and flow measurements made at different ...
