Abstract
A system for well formation includes a first composite umbilical, a winding system configured to hold and dispense the first composite umbilical, a first surface feeder configured to feed the first composite umbilical from the winding system into a first wellbore, and a first bottom hole assembly coupled to the first composite umbilical and configured to receive electric power and a first communication signal via the first composite umbilical. The first bottom hole assembly includes a first tractor and a first pulse power electrode coupled to the first tractor.
