... Abstract This case study looked to identify a perforation design and a perforation charge that measurably increases Perforation Efficiency (PE) and reduces PE variability from stage to stage. Achieving these goals allows for more economic fracture surface area generation as well as more...

... are presented to illustrate its advantages. In a typical SDT, the injection flowrate is reduced in four or five abrupt decrements or "steps", each with a duration long enough for the rate and pressure to stabilize. The pressure-rate response is used to estimate the magnitude of perforation efficiency and near...

... system normally lies along the bottom of the casing. When hydraulically fracturing these intervals, perforation efficiency is difficult to predict since the entry hole diameters and perforation penetrations are not definitive. A perforating system has been developed which provides a consistent entrance...
