Method for generating a flow profile of a wellbore from pulsed neutron logs

A method for generating a flow profile of a wellbore, comprising the following steps:

• (a) collecting a first measurement and a second measurement for each point of a sequence of selected points along the wellbore;
• (b) calculating for each respective point in the sequence of points the arithmetic difference between the first and second measurements collected for the respective point;
• (c) recording for each respective point in the sequence of points the summation of the arithmetic differences for the respective point and for each point of a plurality of points selected from the group consisting of a first plurality of points which precedes the respective point in the sequence of points and a second plurality of points which follows the respective point in the sequence of points;
• and
• (d) generating a liquid flow profile of the wellbore 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 a point in the wellbore is substantially proportional to the magnitude of the slope of the profile corresponding to that point.
