Open the CIPO recordAbstract From the Canadian patent
A method for tool path identification in formation evaluation includes obtaining measurements, of formation properties in azimuthal sectors for each of a plurality of depth levels; calculating, quality factors from the measurements; identifying a centroid or maximum of the quality factors, among the measurements in each of the azimuthal sectors for each depth level; and associating, the centroid or maximum of the quality factors at each depth level along a borehole to form the, tool path. Calculating the quality factors may include parameterizing the measurements, according to at least one factor selected from a spine factor a rib factor, and a volumetric, photoelectric factor. A …
