A METHOD TO CONTROL THE ENVIRONMENT IN A LASER PATH

Title:

A METHOD TO CONTROL THE ENVIRONMENT IN A LASER PATH

Document Type and Number:

WIPO Patent Application WO/2013/113002

Kind Code:

A3

Abstract:

A method of controlling the environment intermediate a laser head and a targeted portion of a bore wall to remove solid material at the wall includes running an umbilical into the bore to position the head, irradiating the targeted portion of the wall using laser light, sensing a light spectrum resulting from irradiation of the solid material, comparing the sensed light spectrum to a light spectrum corresponding to favorable irradiation of the solid material, adjusting the rate of introduction of a laser-compatible material to displace laser-incompatible materials from the laser light path to obtain more favorable irradiation of the solid material. The method enable the conservation of the source of the laser- compatible material or improved irradiation of the solid material for solid removal by using the laser to cut, heat, fracture or melt the solid material.
