API RP 19B

Abstract

<strong>GENERAL</strong><br>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. This document supersedes all previously issued editions of API RP 43.<br>Sections 1 &#8211; 4 of this Recommended Practice provides means for evaluating perforating systems (multiple shot) in 4 ways:<br>1. Performance under ambient temperature and atmospheric pressure test conditions.<br>2. Performance in stressed Berea sandstone targets (simulated wellbore pressure test conditions).<br>3. How performance may be changed after exposure to elevated temperature conditions.<br>4. Flow performance of a perforation under specific stressed test conditions.<br>Section 5 of this Recommended Practice provides a procedure to quantify the amount of debris that comes out of a perforating gun during detonation. The purpose of this Recommended Practice is to specify the materials and methods used to evaluate objectively the performance of perforating systems or perforators.<br><strong>IMPLEMENTATION</strong><br>These procedures become effective as of the date of publication.<br><strong>API REGISTERED PERFORATOR SYSTEMS</strong><br>Information on API Registration of perforator systems can be found in Appendix D.<br><strong>REPORTS AND ADVERTISEMENTS</strong><br>Reports, articles, papers, periodicals, advertisements, or similar publications which refer to results from tests conducted according to API RP 19B must not be worded in a fashion to denote that the American Petroleum Institute either endorses the result cited or recommends or disapproves the use of the perforating system described.<br>Use of data obtained under API RP 19B tests in reports, articles, papers, periodicals, advertisements, or other published material shall include, as a minimum, all test configuration data not specified by API RP 19B or left to the verifying company&#8217;s choosing by API RP 19B and the average measured results of the test.
