| Abstract | We reviewed the facilities currently existing in the reservoir laboratory at IIE, MÈxico. The measurements from the core samples that can be performed are among others; rock total density, grain density, porosity, permeability, compressibility coefficient, thermal conductivity, thermal diffusivity, and specific heat. The discussion is oriented to the techniques of thermal properties measurements. We also reviewed the actual state of the Cerro Prieto Geothermal field, including: the wells of the area IV, the core samples extracted and their measurements made, the well logs taken and the lithology found during drilling. We used the results obtained from the core samples measurements, the temperature and pressure well logs, and the information from the drilling stage of wells of Cerro Prieto IV area. Then we correlated the corresponding depths for each well with their respective parameters in order to identify thicknesses with productive characteristics. We found that the correlation of the parameters used in this work, gave good results for to characterize the reservoir and to identify the interval thicknesses for exploitation. |
