Estimation of Water Saturation in Shale Formation Using In Situ Multifrequency Dielectric Permittivity

Figure 12

Calibration of dielectric core measurement and corresponding water saturation that are required for cores samples to replicate dielectric response of the scanner. (a) Black dashed line is the Archie’s parameter optimized to core measurements. (b) Red points are the results after calibration, and they show the amount of water being required to generate the same dielectric response under the condition of core samples.
