Abstract: A wireline deployed fluid blasting tool for removing obstructions from oil and gas wellbore tubing is disclosed. The tool has an inner tubular mandrel retaining a releasable outer sleeve creating an annular fluid passage in communication with fluid ejection ports. Resilient seals seal the annulus between the tool and the wellbore tubing allowing fluid pressure above the tool to advance the tool through the tubing. Fluid enters the annular fluid passage through fluid perforations in the outer sleeve to exit the fluid ejection ports to create a fluid blast to remove obstructions. The outer sleeve shifts along the inner mandrel by fluid pressure to open fluid inlet passages into the inner mandrel allowing fluid to enter and exit through the mandrel while bypassing the annular fluid passage and fluid ejection ports to facilitate pulling the tool from the tubing.

Abstract: A carrier assembly having at least one sealing cup, a fluid bypass and adjustable wash nozzles, as well as a spear assembly having a central through bore, are attached to the distal end of a length of continuous tubing and inserted in to the flow bore of a pipeline. Fluid is pumped through the annular space between the carrier assembly and the pipeline, providing motive force for advancing the carrier assembly within the pipeline. Fluid can bypass the carrier assembly, enter the central bore of the spear assembly, and return to the surface through the central bore of the continuous tubing. A stuck pig or other obstruction is speared, and thereafter retrieved from the pipeline on the continuous tubing.

Abstract: A method of cleaning a tubular with a cleaning tool that includes the steps of disposing the cleaning tool in the tubular, the cleaning tool having a main body with a first end, a second end, an inlet, an outlet, and a propulsion relief assembly disposed proximate to the second end. The method further includes the steps of sufficiently pressurizing fluid behind the tubular to propel the cleaning tool along the tubular, and increasing the pressure of the fluid to actuate the propulsion relief assembly, whereby fluid is jetted out the outlet and out of the propulsion relief assembly.
