1. A method ( 100 ), comprising: acquiring borehole image data utilizing a downhole tool conveyed within a borehole extending into a subterranean formation, wherein the downhole tool is in communication with surface equipment disposed at a wellsite surface from which the borehole extends; and operating at least one of the downhole tool and the surface equipment to: delineate ( 120 ) a dip and/or a fracture from the acquired borehole image data; create ( 130 ) a gap-filled image from the acquired borehole image data; extract ( 140 ) a fracture segment from the acquired borehole image data; determine ( 150 ) matrix information from the acquired borehole image data; delineate ( 160 ) a heterogeneity from the acquired borehole image data; and analyze ( 170 ) image porosity based on: the dip and/or fracture delineated ( 120 ) from the acquired borehole image data; the gap-filled image created ( 130 ) from the acquired borehole image data; the fracture segment extracted ( 140 ) from the acquired borehole image data; the matrix information determined ( 150 ) from the acquired borehole image data; and the heterogeneity delineated ( 160 ) from the acquired borehole image data.
