1. A method comprising:
conveying an electromagnetic well-logging tool into a wellbore within a geological formation, wherein the electromagnetic well-logging tool includes a transmitter and a receiver;
producing one or more electromagnetic waves using the transmitter of the electromagnetic well-logging tool, wherein the one or more electromagnetic waves interact with the geological formation;
receiving, by the receiver, the one or more electromagnetic waves after the one or more electromagnetic waves have interacted with the geological formation;
generating a plurality of electromagnetic (EM) measurements within a defined frequency range based on the one or more electromagnetic waves received by the receiver; and
determining a contact angle associated with at least one type of solid particle within the geological formation based on the generated plurality of EM measurements, wherein the contact angle quantifies a wettability of the at least one type of solid particle within the geological formation.
