Abstract
The present disclosure relates to a pulsed-power drilling system that includes downhole mixers for restoring optimal electrical properties in drilling fluid. The downhole mixer may include a housing having an uphole and downhole end, a channel to convey the drilling fluid through the housing, and a flow restrictor including an orifice having a fixed diameter positioned in the channel between the entrance and the exit of the channel to create a pressure drop between the entrance and the exit of the channel during a drilling operation. The pressure drop increases shear stress in the drilling fluid to manage electrical properties, such as a dielectric constant, of the drilling fluid. The electrical properties of the drilling fluid facilitate the formation of an electrical arc on a drill bit of the pulsed-power drilling system.
