Anotation

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 and/or system
performance in four ways:
1. Performance under ambient temperature and atmospheric pressure
test conditions into standard casing and concrete targets (4.1);
2. Individual shots into Berea sandstone targets at various defined
stressed conditions, with wellbore and pore pressures at nominally
ambient conditions (4.2);
3. How performance can be changed after exposure to elevated
temperature conditions (4.3);
4. 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. See more
