Abstract: A casing has a plurality of joints of pipe joined by a plurality of casing collars, and an outer surface. A high-frequency alternating current (AC) source electrically is coupled to the casing. A coating of insulating material covers the entire outer surface of the casing. The coating has an opening that exposes a casing portion. The casing and the coating of insulating material define a capacitive electrode having an impedance Z f with a magnitude |Z f | at the frequency of operation f of the high- frequency AC source. Z f is low enough to allow current from the high-frequency AC source to be injected from the casing through the coating of insulating material into a surrounding formation. The casing portion has a resistance R to direct current (DC) with a magnitude that is very large compared to |Z f |.

Abstract: A disclosed downhole drilling system may include a drill bit electrically coupled to a pulse-generating circuit to generate electrical arcs between first and second electrodes during pulsed drilling operations, a sensor to record responses to electromagnetic or acoustic waves produced by the electrical arcs, and a sensor analysis system. The electrical arcs occur at different azimuthal locations between the electrodes. The sensor analysis system may obtain a plurality of measurements representing first responses recorded by the sensor during a pulsed drilling operation, generate a model of a source of the electrical arcs based on the measurements, obtain an additional measurement representing a second response recorded by the sensor during the operation, and determine a characteristic of a formation near the drill bit using an inversion based on the model and the additional measurement. The determined characteristic may be used to determine dip parameters or construct images of the formation.
