Abstract
This application relates to systems and methods for stimulating hydrocarbon bearing formations using a downhole laser tool.
Claims24
A laser perforation tool configured for use in a downhole environment of a wellbore within a hydrocarbon bearing formation, the tool comprising:
- a plurality of perforation means disposed within an elongate tool body, each perforation means configured for perforating the wellbore and comprising:
- one or more optical transmission media, the one or more optical transmission media being part of an optical path originating at a laser generating unit configured to generate at least one raw laser beam, the one or more optical transmission media configured for passing the at least one raw laser beam;
- and
- a laser head coupled to the one or more optical transmission media and configured for receiving the at least one raw laser beam, the laser head comprising an optical assembly for controlling at least one characteristic of an output laser beam;
- and
- deployment means for extending the plurality of perforation means through one or more exit ports disposed in a side wall of the tool body.

A method of using a laser tool to stimulate a hydrocarbon-bearing formation, the method comprising the steps of:
- positioning the laser tool within a wellbore within the formation, the laser tool comprising a plurality of perforation means disposed therein;
- passing, through one or more optical transmission media, at least one raw laser beam generated by a laser generating unit at an origin of an optical path comprising the one or more optical transmission media, where the plurality of perforation means are coupled to the laser generating unit;
- deploying the plurality of perforation means out of a body of the tool;
- delivering the raw laser beam to an optical assembly disposed within each of the perforation means;
- manipulating the raw laser beam with each optical assembly to produce an output laser beam from each optical assembly;
- and
- delivering the output laser beams to the formation.
