Thereby, the interface conductivity is a decisive parameter for the bulk resistivity for the sample at reservoir salinities [15]. 5.3. Resistivity Structure of High-Temperature Fields and Relation to the CEC High-temperature geothermal fields in volcanic areas of the world have, in general, a ...
The temperature was set to 23 ◦C. For each humidity increase, the weight was measured until equilibrium was reached. The minimum time for each RH increase was set to 2 h, and the maximum to 48 h. The sorption isotherms between 35% and 95% RH were described using the Guggenheim, ...
Cation-exchange capacity (CEC) measurements are widely used to quantify the smectite content in altered rocks. Within this study, we measure the CEC of drill cuttings in four wells from three different high-temperature geothermal areas in Iceland. The CE
