Abstract:
A laser-jet apparatus for creating a penetration through a stress region adjacent to a wellbore includes an outer tool housing, the outer tool housing having a housing central bore. A laser assembly includes a lens case with an outer diameter that is smaller than an inner diameter of the housing central bore, defining an annular passage between the outer tool housing and the lens case. A focusing lens and a collimating lens are located within the lens case. The focusing lens is shaped to control the divergence of a laser beam and the collimating lens is shaped to fix the diameter of the laser beam. A jet fluid path is located in the annular passage, the jet fluid path shaped to merge jet fluid with the laser beam. The outer tool housing has a frusto-conical tip for directing the combined jet fluid and laser beam to the stress region.
