US 10,121,261 B2 · Automatic dip picking in borehole images

Abstract

The techniques and device provided herein relate to receiving, via a processor, image data representative of a borehole of a well. The technique may include generating dequantized image data based on the image data, such that the dequantized image data filters one or more artifacts present in a Hough transformed version of the image data. One or more dip orientations (inclination and azimuth) associated with one or more formation dips present in the image data may be determined based on the dequantized image data. The technique may also include performing an a-contration validation algorithm for for the one or more formation dips to verify whether at least a formation dip having the or one of the possible dip orientation is present at a predetermined measured depth in the image data.

A method, comprising:

receiving, via a processor, image data representative of a borehole image obtained by a downhole tool;
generating, via the processor, dequantized image data based on the image data, wherein the dequantized image data filters one or more artifacts present in a Hough transformed version of the image data;
determining, via the processor, one or more possible dip orientations associated with one or more formation dips present in the image data based on the dequantized image data;
performing, via the processor, an a-contrario validation algorithm for the one or more formation dips to verify whether at least a formation dip having the or one of the possible dip orientation is present at a predetermined measured depth in the image data.
