Abstract
Apparatus and methods of drilling using a bitless drilling assembly can include a propellant chamber configured to store a liquid propellant for drilling. The bitless drilling assembly can include a burner nozzle connected to the propellant chamber via one or more passages to route the liquid propellant from the propellant chamber to the burner nozzle. The bitless drilling assembly can include an ignitor configured to ignite the liquid propellant as the liquid propellant escapes the burner nozzle. The bitless drilling assembly can include a diverter cage placed in a path of the inside passage to divert one or more propellant capsules from the inside passage to a capsule blade. The capsule blade can be configured to puncture the one or more propellant capsules to allow the propellant to flow into a reservoir and route the propellant to the propellant chamber. The bitless drilling assembly can be controlled automatically during drilling.
