n: a tubular device that, when lowered to a selected depth within a well, fires bullets through the casing to provide holes through which the formation fluids may enter the wellbore.

n: A kind of tubing device, tripped in to the predetermined depth, ejecting bullet and breaking through cement stone and casing to form a passage of oil and gas.

v: to pierce the casing wall and cement of a wellbore to provide holes through which formation fluids may enter or to provide holes in the casing so that materials may be introduced into the annulus between the casing and the wall of the borehole. Perforating is accomplished by lowering into the well a perforating gun, or perforator, which fires electrically detonated bullets or shaped charges. See bullet perforator;jet-perforate, perforating gun.

n: to pierce the casing wall and cement,allowing formation fluids to enter the wellbore and flow to surface. This is a critical stage in the completion of a well. Perforating may also be carried out during workover operations.
