How to avoid perforating problems
This article cautions that the literature on perforating technology can be confusing when you try to apply it to a real situation. Most of the basic information is easy to understand. But as more lab studies and computer modeling studies are published, it becomes more difficult to decide what parameters are important. A review of the current literature can lead to the conclusion that a well capable of producing 10 MMcfd of gas may be restricted to less that 1.0 MMcfd by the perforations. Locke's publication in 1981 showed the effects of shot penetration depth on well productivities. He noted that various investigators agree that deeper penetration does improve results, although there is some disagreement over the absolute amount of improvement among them. From these data, one may expect that if 9-in. penetrations are achieved with a 90/sup 0/ phased perforating gun, at four shots per foot, a well would be stimulated by approximately 10 percent over what might be expected from an open hole completion.
