Strength (UCS) of Carbonates Using Compressional and Shear Acoustic Velocities |
摘要 |
Acoustic velocities measured downhole are used to predict a rock strength using results of a regression analysis that include grain size. The grain size can be obtained from drill cuttings or from NMR measurements. The determined rock strength is used in drilling operations.
