Abstract
The downhole tool may include an electrical power source, a positive and a negative electrode, and at least one sensor. The positive and negative electrodes may be configured to generate an electric field between the positive and the negative electrode with an electrical charge from the electrical power source and discharge the electric charge through a downhole formation. The at least one sensor may be configured to detect quantum particles dislocated by at least one of the electric field and the discharged electrical charge to determine downhole information from at least one of a travel time of the quantum particles, a composition of the quantum particles, a quantity of the quantum particles, and a charge of the quantum particles.
