Definition - What does Tubing Broach mean?
A Tubing Broach is a tool used for the maintenance of broken or collapsed tubing. It is a downhole tool that cuts off the burrs found in the tubing. These burrs can be caused due to reasons such as rust, perforation and deformation of the tubing. This tool has a cutter(s) embedded on it, which when thrusted into the tubing, it removes the inner material which is causing the inefficient working of the tubing. The cutter is pushed inside the tubing with force that also straightens out any deformation, thus making the tubing workable.
Petropedia explains Tubing Broach
Tubing is primarily run down through a wellbore to facilitate the transmission of the fluids from the reservoir. It is inserted and fixed into the wellbore and forms an important conduit for the production of fluids. Since the underground fluids are extracted with high pressure from the bottom to the surface, the tubing is required to be strong enough to bear the pressure of the fluids. Also, it should be of a size that accommodates the volume rate of oil and gas produced. However, the tubing can get jammed with particles, rust or grime from within, hence interrupting the smooth extraction of the oil and gas. Therefore, it might require repair and maintenance.
Tubing broach, a downhole slickline tool is used to cut through the inner burrs caused due to perforation, rust or any other reason. The tool's cutter profile helps in getting rid of the inner deformity easily, as it is pushed inside the tubing with high impact. The high impact causes the tube to get in shape, therefore, resuming the regular production.
