Record number: 2, Textual support number: 1 OBS

bullet perforating: An early perforating method that used a hardened steel bullet or projectile, propelled by an explosive charge, to create a perforation tunnel. This method creates a low-permeability crushed zone and leaves the bullet and associated debris jammed at the end of the tunnel. Jet perforating is now the preferred method.  3, fiche 2, Anglais, - bullet

A tubular device that, when lowered to a selected depth within a well, fires bullets through the casing in order to provide holes through which the well fluids may enter.  2, fiche 3, Anglais, - bullet%20perforator

Record number: 3, Textual support number: 1 CONT

Sometimes, where the bore fluid yield has been disappointing, it has been possible to increase the flow by perforating the production casing by means of a bullet type gun consisting of a special barrel, having four chambers per foot, each housing a hardened 3/4-in steel bullet(19mm) and an explosive charge.  7, fiche 3, Anglais, - bullet%20perforator

Record number: 5, Textual support number: 1 DEF

To burn a hole through the casing with a shaped charge of high explosives instead of a gun that fires a projectile, as is used in bullet perforating.  1, fiche 5, Anglais, - jet%2Dperforate

Record number: 5, Textual support number: 1 OBS

The gun with loaded charges is lowered into the hole to the desired depth. Once detonated, the charges form short, penetrating jets of high-pressure gases that produce holes in the casing and cement and some distance into the formation. Formation fluids then flow into the wellbore through these holes, or perforations.  1, fiche 5, Anglais, - jet%2Dperforate
