ESTIMATE OF FORMATION MOBILITY FROM STONELEY WAVEFORMS

摘要

Various embodiments include apparatus and methods to estimate formation mobility from Stoneley waveforms. An objective function can be generated that represents misfit between measured Stoneley pressure values and synthetic pressure values. A minimization process can be applied to the objective function to estimate formation mobility and intrinsic attenuation. Additional apparatus, systems, and methods are disclosed.
