oa Sweep Efficiency in a Waterflooding Pattern Processed by Horizontal Wells

Joshi [1] derived an equation to compute the horizontal well production considering that the flow is symmetrical and similar to the flow into a pipe-like radial fracture. However this is a rode approximation especially for long and very long horiwntal well sections where the pressure loss along the well pipe shell be taken into consideration. Some results [2,3] have shown that the pressure loss can play a significant role on the horizontal well performances. On the other hand the pressure loss along the horizontal section generate a non uniform flux and potential distribution along the well. This well influence the front displacement in a waterflooding process.
