From a perforation design perspective, the number of perforations, entry-hole diameter (EHD), and perforation phasing are three of the most important perforation design parameters that should be tied back to production results, if any testing is being performed. The number of perforations is typically designed based on the limited entry technique for optimum production enhancement in unconventional reservoirs. However, various testing on the number of perforations, EHD, and perforation phasing must be done to understand the outcome of each test. It is very important to test one variable at a time to understand the sole impact of that parameter on production.
