... A large database was used, in this study, to characterize a sandstone reservoir. The data consists of geophysical well logs, lithological descriptions, facies variations and, petrophysical parameters. The logs were registered into the wells; the lithology and facies were observed in cores; and...

... Digital rock physics is an image-based computational technique used to study the physical properties of rocks. Digital rock studies originated in sandstones, which are quartz-dominated rocks with varying amounts of feldspar, calcite, and clay. However, there are significant differences in the...
