One of the ways minerals are extracted from epithermal and porphyry deposits is by the use of open pit mines. These mines are significant challenges to progress from exploration to operational mining. Exploration would identify the prospect. Detailed exploration would identify showing (surface indication of mineralisation that requires further investigation […]

Geologists would visually inspect and log the core to create a record of rock types (lithology) and their sequence (stratigraphy). Elemental and mineral composition could be determined using techniques like X-ray fluorescence analysis. The degree of alteration would be examined to help predict rock permeability for geothermal fluid circulation. Core […]
Cooling of closed system working fluids is essential for the efficiency of Binary Organic Rankine Cycle (ORC) power generation. Several type of cooling technologies exist:
New Zealand has complex geology with extensive volcanic systems and seismicity as well as being among the world leaders (6th) in geothermal energy production. To the north of New Zealand and beneath the eastern North Island, the Pacific Plate subducts beneath the Australian Plate. Within the South Island, the transform […]
There are multiple software solutions suitable for the necessary technical modelling and simulation. The following description utilises some of these software solutions. A detailed 3D numerical conceptual simulation model in LEAPFROG is a static representation that can be calibrated as a natural state model.
Exploration and development wells are a major cost component of geothermal energy projects. In the exploration phase, when wells are being used to derisk geothermal prospects, it is important to be as economic as possible, so slimhole wells have been increasingly utilised to reduce costs.
