Abstract
Method for automatic detection of planar heterogeneities crossing the stratification of an environment. This method for automatic detection of planar heterogeneities crossing the stratification of an environment, from images of borehole walls or developments of core samples of the said environment, in which an original image defined in a system of axes (X.sub.1, Y.sub.1, Z.sub.1) which is associated with a borehole whose axis is Z.sub.1 is used, the said image containing, for a zone of the environment through which the borehole passes, planar heterogeneities consisting of stratification planes (2 to 14) and of planar heterogeneities (15 to 23) intersecting the stratification planes, is characterized in that it consists in: PA1 determining a dominant orientation of the stratification planes which lie in at least one part of the said original image, PA1 filtering the original image in order to eliminate the planar heterogeneities of the stratification planes (2 to 14) which lie in the dominant direction, and PA1 determining, on the said filtered image, at least contour segments (15' to 23') of the heterogeneities which intersect the stratification planar heterogeneities.
