Analysis of Babu and Odeh's Model

Abstract

In this work, Babu and Odeh’s model for estimating flow rate from partially penetrating systems is studied. A VBA code is written in order to simulate the model and its results are compared against simulations using Eclipse Software. Sensitivity to different parameters is analyzed and an increasing-decreasing behavior as the reservoir’s length is increased is specifically addressed and analyzed.

After simulating different scenarios it is observed that Babu and Odeh’s model predicts that there will be a specific reservoir’s length for which a maximum flow rate will be predicted. An explicit analytical expression is obtained for one of the cases considered in the model.

The results obtained are compared against Eclipse runs, it is observed that the model is reasonably accurate, and that the reservoir’s length at which the maximum flow rate onsets is similar in both cases.

It is concluded that the model is accurate within its simplistic assumptions, but it is in these same assumptions that it might yield very different results than reality itself.
