Abstract
A high power laser system for providing laser beams in various laser beam patterns along a laser beam path that is positioned to provide for the in situ laser processing of materials in tubulars, such as pipes in a hydrocarbon producing well. Laser treating for providing flow assurance by direct and indirect laser processing of materials interfering with flow.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . A high power laser system for performing laser operation on a material in a borehole in the earth, the system comprising:
a. a high power laser having the capability of providing a laser beam having at least about 20 kW of power; b. a long distance high power transmission cable for providing the high power laser energy deep within a borehole hole; and, c. a high power laser tool having a high power laser optic to provide an annular laser beam pattern.
