Methods and apparatus for removal and control of material in laser drilling of a borehole

Title: Methods and apparatus for removal and control of material in laser drilling of a borehole

Abstract

The removal of material from the path of a high power laser beam during down hole laser operations including drilling of a borehole and removal of displaced laser effected borehole material from the borehole during laser operations. In particular, paths, dynamics and parameters of fluid flows for use in conjunction with a laser bottom hole assembly.
