API RP 19B, 3rd Edition, July 2021 – Evaluation of Well Perforators
This recommended practice describes standard procedures for evaluating the performance of perforating equipment so that representations of this performance may be made to the industry under a standard practice.
Section 4 provides methods for evaluating perforator or system performance, or both, in four ways:
a) performance under ambient temperature and atmospheric pressure test conditions into standard casing and concrete targets (4.1);
b) individual shots into Berea sandstone targets at various defined stressed conditions, with wellbore and pore pressures at nominally ambient conditions (4.2);
c) how performance can be changed after exposure to elevated temperature conditions (4.3);
d) flow performance of a perforation under specific stressed test conditions (4.4).
Section 4.5 provides a procedure to quantify the amount of debris that comes out of a perforating gun during detonation, and during conveyance out of the well. Section 4.6 provides a procedure to measure the swell of a perforating gun.
The purpose of this recommended practice is to specify the materials and methods used to evaluate objectively the performance of perforating systems or perforators.
