Rock Sampling
DataAcquisition Under a detailed investigation, a systemat
Under a detailed investigation, a systematic sampling procedure is often developed. Much of this will depend on where the wells are drilled or if there are surface manifestations present. When exploring a geothermal resource the rock samples can come from above and below the target reservoir, but the most valuable and critical samples are from the reservoir itself. There are geostatistical techniques which can be very useful for characterizing the occurrence of fractures or other specific rock properties (Babadagli & Develi, 2000; Marche, et al., 2002; Fabbri, 1997). Once a rock sample has been collected there are various procedures that can be done to measure the fluid circulation, chemical composition, porosity, permeability, thermal conductivity, formation temperature, etc.

'''Subsurface Sampling''' A rock sample for geothermal exploration is typically collected from a drilled well, and initial analysis of the rock type, mineralization, composition, textures, etc. are collected in the field at the drill site or from core and cutting samples that have since been stored in a repository. However, the more in depth rock properties often require laboratory tools. '''Surface Sampling'''<br/> There are rock samples that can be collected on the surface, in outcrop, which may reveal important information about the geothermal resource at depth. These hand samples can be collected using a rock hammer or sledge.

StratInfo Provides information about the time and environment which formed a particular geologic unit. Microscopic rock textures can be used to estimate the history of stress and strain, and/or faulting.  +
ThermalInfo Thermal conductivity of a rock sample can provide information to calculate heat flow. Hydrothermal alteration of a rock sample can indicate certain temperature or fluid compositions.  +
