Hybrid drilling and trimming tool and methods

Abstract

A system includes a drill pipe, a fiber optic housing, a laser housing, a conduit, and a fiber optic cable. The drill pipe extends from a surface location into the wellbore. The fiber optic housing is connected to the drill pipe. The laser housing is connected to the fiber optic housing and houses a laser. The drill bit, the laser housing, the fiber optic housing, and the drill pipe are configured to rotate. The conduit extends through the drill pipe, the fiber optic housing, the laser housing, and the drill bit. The fiber optic cable is housed in the fiber optic housing, is disposed within the conduit, and extends from the surface location to the laser located in the laser housing. The laser emits a laser beam into the wellbore. Rotation of the laser housing rotates the laser beam in a circular plane perpendicular to the wellbore.
