System and method for generation of alerts and advice from automatically detected borehole breakouts

摘要

A method for generating an alert or advice for drilling a borehole penetrating an earth formation includes: receiving with a processor a borehole image from a downhole tool disposed at a drill tubular drilling the borehole; detecting a first breakout and a second breakout shifted approximately 180° apart from the first breakout if breakouts are in the image using a method for detecting breakouts implemented by the processor; and generating an alert or advice with the processor if the first and second breakouts are detected.

1. A method for generating an alert or advice for drilling a borehole penetrating an earth formation, the method comprising:
receiving with a processor a borehole image from a downhole tool disposed at a drill tubular drilling the borehole; detecting a first breakout and a second breakout shifted approximately 180° apart from the first breakout if breakouts are in the borehole image using a method for detecting breakouts implemented by the processor comprising receiving with the processor a drilling fluid pressure for a borehole depth where the borehole image was obtained and comparing the drilling fluid pressure to a shear-failure gradient in a drilling pressure window; and generating an alert or advice with the processor if the first and second breakouts are detected.
