Abstract: The disclosure, in on aspect, provides a method for performing a laser operation in a wellbore that includes displacing a wellbore fluid with a laser-compatible medium proximate a location in the wellbore where a work is desired to be performed; positioning a laser head proximate the laser-compatible medium; and passing a laser beam via the laser-compatible medium to the location for performing the laser operation. In another aspect, the disclosure provides a laser apparatus for performing a laser operation at a worksite having a fluid that includes a laser power unit that supplies laser energy to a laser head placed proximate the worksite; a fluid displacement unit that displaces at least a portion of the fluid adjacent the worksite with a laser-compatible medium; and a controller that operates the laser head to pass the laser beam to the worksite through the laser-compatible medium. In another aspect, the disclosure provides an imager associated with the laser apparatus that provides images of the worksite.

Abstract: A tool containing a solid combustible material is used to provide a pipe-cutting flame and to direct a pipe-cutting flame against a casing or tubular. The nozzles can be configured in any desired array and intensity. In the preferred embodiment, a rectangular window is burned away completely if the nozzles are sufficiently intense or the window is formed in segments if other distributions are used. The device can be anchored by a packer or anchor and can be run in the wellbore on tubing, wireline or electric line. The window can be produced in a single trip. The tool can be removed and a kick-off diverter installed adjacent the window for drilling the lateral.
