... effects that influence post-shot flow into perforations. The flow streamlines of a low-shot density gun can be quite different than a high-shot density gun, for example. To further illustrate the differences, we made a series of calculations comparing the flow in Section 4 axial and radial flow...

... limitations.The alternative practical approach is the use of a skin factor in open hole calculations resulting in the same flow performance as that of the perforated well.However most of the skin calculations done today are based on single-phase flow conditions. In this work, we have developed a method to...

.... This was a set of control experiments, or control calculations. These calculations should not be confused with a gas well with 10% water saturation that produces no water. In this first case of a single phase, it is numerically true, and we have verified it with the model presented here, that the...
