Embodiments relate to removing residue from a well bore and well bore equipment with a treatment fluid composition, and in some embodiments, to treatment fluid compositions that comprise nanoparticles. An embodiment provides a method of removing drilling fluid residue from the surfaces of well equipment. The method comprising: applying a solid nanoparticle film to at least a portion of the surfaces of the well equipment with a treatment fluid comprising solid nanoparticles; and allowing the solid nanoparticles to interact with the surfaces of the well equipment and the drilling fluid residue adhered to the surfaces of the well equipment to remove at least a portion of the drilling fluid residue from the surfaces of the well equipment.

The methods for cleaning pipes with service connections includes vacuuming therethrough abrasive projectiles first in one direction, and thereafter, in an opposing direction, with additional cleaning achieved by opening of service connection valves during vacuuming. By opening service connection valves during vacuuming, debris and moisture are removed from within the service connections. Vacuuming direction reversal removes shadow deposit areas.

The invention relates to a method for cleaning a heat exchanger. The heat exchanger comprises a plurality of tubes extending between a first header and a second header, and further comprises an insertion unit for introducing a plurality of projectiles thereinto. A first step of the method comprises pumping a fluid into the first header. A second step comprises inserting the plurality of projectiles into the fluid, such that the plurality of projectiles are distributed within the fluid. A third step comprises flowing the fluid and the projectiles through the tubes, such that the projectiles abrades at least one tube. A fourth step comprises discharging the fluid and the projectiles out of the second header. Among the plurality of projectiles, at least one projectile has a different specific gravity, relative to the fluid, from at least one of the remaining projectiles.

An apparatus for treating an interior surface of a workpiece comprising at least three nozzles ejecting treating material, with a first one and a second one ejecting the treating material substantially along first and second collinear lines. A third one of the nozzles ejects the treating material substantially along a third line substantially perpendicular to the first and second lines. The treating material ejected from the first one intersects with the treating material ejected from the second one at a first intersection area to radially deflect to form a first radial spray. The treating material ejected from the third one intersects with the first radial spray at a second intersection area to form a second radial spray of treating material. The interior surface of the workpiece adjacent the second intersection area is treated with the treating material of the second radial spray.

A system and method for pipe cleaning are disclosed, which include arranging at least one pump to draw a flow of water from the body of water. An output of the at least one pump is fluidly connected to the pipe through a junction disposed between the one end of the pipe and the free end of the pipe, and the at least one pump is activated to draw the flow of water and provide the flow of water to the pipe through the junction such that a flow of water passes through the pipe to remove the debris. The debris is thus entrained in the flow of water and ejected from the pipe through the free end into the body of water until the pipe is clean.
