Compacting shale
WebJun 24, 2015 · 100 = acoustic transit time in compacted shales (μsec/ft) The shale compaction coefficient (C) generally ranges from 1.0 to 1.3, depending on the regional geology. The highest velocities observed in sandstones approach 20,000 ft/sec (50 μsec/ft), but most sandstones have a lower matrix velocity. WebShrinkage = volume after compaction/volume before excavation. Both the loose and compacted volume are calculated from the bank volume. Example: If you are excavating dry clay it is listed as having a swell of 50% and a shrinkage of -10%. That means that for every 1 cubic metre/yard of material that you excavate the volume increases by 50%.
