Paper Number: SPWLA-2022-0002
..., such as multi-frequency dielectric logs, the objective of this study. Using an open-ended coaxial laboratory test probe operating between 10 MHz and 1 GHz, multi-frequency dielectric data are measured on clean outcrop core samples of both carbonate and sandstone. The data are analyzed by using the traditional...

.... The outputs of this workflow include water saturation and wettability. To experimentally verify the reliability of the introduced workflow, we chemically alter the wettability of core samples to be water-wet, mixed-wet, or oil-wet. We confirm and quantify the wettability level in each core sample using...
