20120074110 | FLUID LASER JETS, CUTTING HEADS, TOOLS AND METHODS OF USE - There are provided high power laser systems, apparatus and methods for performing laser operations in particular in environments where an optically obstructive medium may be present in the laser beam path, such as within the borehole of an oil, gas or geothermal well, or below the surface of a body of water. Further, there are provided such systems, apparatus and methods that manage potentially damaging back reflections that may be generated during such laser operations. The high power laser operations would including tasks, such as, window cutting, pipe cutting and other workover completion activities, as well as decommissioning, plugging and abandonment tasks. | 03-29-2012 |
20120217018 | LASER ASSISTED BLOWOUT PREVENTER AND METHODS OF USE - There is provided a high power laser assisted blowout preventer and methods of use. In particular, there are provided systems and assemblies for utilizing high power laser energy within a blowout preventer to cut tubulars that are present within the bore of the blowout prevent, reducing the risk that such tubulars will inhibit the ability of the blowout preventer to seal a well. | 08-30-2012 |
20120255774 | HIGH POWER LASER-MECHANICAL DRILLING BIT AND METHODS OF USE - There is provided a high power laser-mechanical bit for use with a laser drilling system and a method for advancing a borehole. The laser-mechanical bit has a beam path and mechanical removal devices that provide for the removal of laser-affected rock to advance a borehole. | 10-11-2012 |
20130228372 | HIGH POWER LASER PERFORATING AND LASER FRACTURING TOOLS AND METHODS OF USE - There are provided high power laser perforating tools and methods of delivering laser energy patterns that enhance the flow of energy sources, such as hydrocarbons, from a formation into a production tubing or collection system. These tools and methods precisely deliver predetermined laser beam energy patterns, to provide for custom geometries in a formation. The patterns and geometries are tailored and customized to the particular geological and structural features of a formation and reservoir. | 09-05-2013 |
20130228557 | TOTAL INTERNAL REFLECTION LASER TOOLS AND METHODS - There is provided high power laser tools and laser heads that utilize total internal reflection (“TIR”) structures to direct the laser beam along a laser beam path within the TIR structure. The TIR structures may be a TIR prism having its hypotenuse as a TIR surface. | 09-05-2013 |
20140000902 | REDUCED MECHANICAL ENERGY WELL CONTROL SYSTEMS AND METHODS OF USE | 01-02-2014 |
20140231085 | LASER SYSTEMS AND METHODS FOR THE REMOVAL OF STRUCTURES - There is provided high power laser systems, high power laser tools, and methods of using these tools and systems for cutting, sectioning and removing structures objects, and materials, and in particular, for doing so in difficult to access locations and environments, such as offshore, underwater, or in hazardous environments, such as nuclear and chemical facilities. Thus, there is also provided high power laser systems, high power laser tools, and methods of using these systems and tools for removing structures, objects, and materials located offshore, under bodies of water and under the seafloor. | 08-21-2014 |
