Title:
SYSTEM AND METHOD FOR AUTOMATIC DETECTION AND ANALYSIS OF BOREHOLE BREAKOUTS FROM IMAGES AND THE AUTOMATIC GENERATION OF ALERTS
Document Type and Number:
WIPO Patent Application WO/2012/054146
Kind Code:
A3
Abstract:
Disclosed is a method for detecting a pair of opposing breakouts in a borehole penetrating an earth formation. The method includes: conveying a downhole tool configured to perform measurements of a property of the earth formation; producing an image of the earth formation from the measurements, the image comprising a plurality of sectors; dividing the sectors into radial segments, each segment corresponding to an opposite segment; rotating the segments at least one sector at a time until a specified angle is achieved; calculating an average value for the measurements associated with each segment for each rotation of the segments; stacking the average values for opposing segments to produce stack values; determining a maximum or minimum stack value; determining if the maximum or minimum stack value exceeds a threshold value; and detecting the first breakout and the second breakout if the maximum or minimum stack value exceeds the threshold value.
