[54] SYSTEMS AND METHODS FOR DIELECTRIC MAPPING DURING PULSED-POWER DRILLING
[57] Abstract: A downhole drilling system is disclosed. The downhole drilling system may include a pulse-generating circuit, a drill bit including a first pair of electrodes electrically coupled to the pulse-generating circuit to receive a first electrical pulse from the pulse-generating circuit and form a first electrical arc between the first pair of electrodes during a pulsed drilling operation; a sensor to record responses to the first electrical pulse during the pulsed drilling operation; and a sensor analysis system communicatively coupled to the sensor, the sensor analysis system configured to obtain a first measurement from the sensor representing the responses recorded by the sensor during the pulsed drilling operation, and determine a first value of the dielectric constant associated with a portion of a formation in proximity to the drill bit, the first value of the dielectric constant based on the first measurement.
