WebNov 2, 2006 · The popular Joshi model slightly overestimated the flow resistance of a horizontal well. As a result of this, the Joshi model underpredicts the productivity index (PI) of a horizontal well by a few percent. In the extreme case in which vertical permeability goes to zero, the Joshi model predicts a 0.0 stb∕day-psi PI, which is wrong. http://en.labthink.com/en-us/literatures/detailed-introduction-to-material-permeability-indexes.html
