ABSTRACT:
Data representing a two-dimensional image of the resistivity of a sector of a borehole wall is processed to produce selected flow-line data delineating the boundaries of beds of subsurface earth formations along sectors of the borehole. The latter bed-delineating image data for several circumferentially-spaced sectors is further processed to derive and present data defining the orientations of dip planes, by matching the bed-delineating flow-lines for the several sectors. This is done by focusing the latter flow-lines on a root flow-line, correlating those flow-lines to the root flow-line, and linking the flow-lines to the root flow-line according to a path of minimum cumulative cost.
