Abstract

Apparatus and methods for use with borehole image data to: delineate a dip and/or a fracture from the borehole image data; create a gap-filled image from the borehole image data; extract a fracture segment from the borehole image data; determine matrix information from the borehole image data; delineate a heterogeneity from the borehole image data; and analyze image porosity. The image porosity analysis is based on: the dip and/or fracture delineated from the borehole image data; the gap-filled image created from the borehole image data; the fracture segment extracted from the borehole image data; the matrix information determined from the borehole image data; and the heterogeneity delineated from the borehole image data.
