n: 1. the inside diameter of a pipe or a drilled hole. 2. the diameter of the cylinder of an engine. v: to penetrate or pierce with a rotary tool. Compare tunnel.

n: Refers to the cylinder liner of pipe or internal diameter of wellbore.

the inside diameter of a tool or pipe.

the area of the rock adjacent to the perforation tunnel where permeability may be 50% less than initial, undamaged permeability.

the fracturing of a perforation tunnel. Often used to bypass damage or increase permeability.

packing the perforation with gravel to prevent tunnel collapse.

packing the perforations with gravel to prevent tunnel collapse.

n: a relatively small container of high explosive that is loaded into a perforating gun. On detonation, the charge releases a small, high-velocity stream of particles (a jet) that penetrates the casing, cement, and formation. See perforating gun.

n: An explosive device that utilizes a cavity-effect explosive reaction to generate a high-pressure, high-velocity jet that creates a perforation tunnel. The shape of the explosive material and powdered metal lining determine the shape of the jet and perform

a shaped explosive charge for perforating steel pipe.

v: in pipeline construction, to penetrate or pierce manually. Compare bore.
