Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3581244
... introduce a method to predict reservoir porosity from seismic velocity in clastic sedimentary basins consisting mainly of sand and shale sequences. It entails using velocity as a measure of compaction in a rock-physics study instead of commonly used depth of burial. We present the methodology...
