A system to clean a tubular member may include an apparatus to support a tubular member having a bore with a longitudinal axis extending therethrough, and a fluid dispensing system disposed adjacent to an opening of the apparatus, the fluid dispensing system having a nozzle to dispense fluid therefrom. An apparatus may also include a first wiper section and a second wiper section, in which the first wiper section and the second wiper section are movable with respect to each other towards a point of convergence. The first wiper section and the second wiper section may be connected and movable with respect to a base between an open position and a closed position. The system may also include a pipe guide disposed adjacent to an opening of a bore of a pipe handling apparatus, and a wear sensor coupled to the pipe guide.

An assembly configured to be disposed within a well at an intersection of a parent bore of the well and a lateral bore of the well is provided. The assembly includes a junction having a mainbore leg and a lateral leg, as well as a passage in the mainbore leg configured to receive a flowing fluid. A port in the mainbore leg is in fluid communication with the passage such that the flowing fluid in the passage creates a suction at the port to draw debris in the well through the port and into the passage.

In the auger cleaning device (8) according to the invention, in the closed configuration the tool-holder support forms a pass-through opening (82) arranged for allowing the passage of a helical drilling tool (6), the cleaning tool (170) engaging with the screw of the drilling tool (6) and, actuated by the actuation system (12, 12', 12", 4), is arranged for rotating around the drilling tool (6) following at least one of its threads (60) so as to remove the debris lying on the drilling tool (6). In the open configuration the cleaning tool (170) is disengaged from the drilling tool (6) and preferably farther from it, with respect to when it is in the closed configuration.
