New procedures are proposed to help estimate the distance to the discontinuity under certain conditions with good accuracy. These procedures can be applied using the derivative of the pressure buildup test data if the mobility ratio is less than unity. A 3-D numerical model is used to generate pressure transient data from synthetic data for a vertical well. The reservoir is considered as a composite reservoir where the inner zone contains the oil phase, and the outer zone contains the water phase. Some of the parameters that control the accuracy of the proposed analysis procedure are the producing time and the external reservoir radius. The procedures are useful in monitoring the position of the edge water front for future planning development purposes. [Received: April 12, 2014; Accepted: November 11, 2014].
