Abstract

Some implementations include a system comprising at least one coiled tubing extending from a surface of a wellbore to a bottomhole assembly (BHA); a power cable to be housed either inside or outside the at least one coiled tubing and to electrically couple a power supply at the surface of the wellbore with the BHA. The BHA comprises at least one capacitor to store electrical power received from the power supply via the power cable housed in the at least one coiled tubing; and at least one electrode electrically coupled to the at least one capacitor to receive the stored electrical power from the at least one capacitor and to periodically emit pulsed power discharges into a subsurface formation to drill the wellbore based on the stored electrical power received from the at least one capacitor.
