Abstract

A method for generating a flow profile of a wellbore whereby a first measurement and a second measurement are collected for each point of a sequence of selected points along the wellbore. For each respective point in the sequence of points, the arithmetic difference between the first and second measurements collected for the respective point is calculated, and the summation of the arithmetic differences for the respective point and for each point which follows the respective point in the sequence of points is recorded. A flow profile of the wellbore is generated by plotting the value of the summations calculated for each point of the sequence of points, wherein the magnitude of the potential productive flow from that point in the wellbore, is substantially proportional to the magnitude of the slope of the profile corresponding to that point.
