Quasi-static stoneley slowness estimation

A method for producing an Quasi-Static Stoneley Slowness log comprising:

• recording a pressure wave at a first receiver;
• inputting borehole characteristics into an information handling system;
• performing a forward model with the information handling system;
• building a low-frequency Stoneley Dispersion Model;
• propagating a waveform to a second receiver;
• minimizing a misfit between predicted and measured Stoneley waveform data to estimate final Stoneley dispersion;
• and
• identifying Quasi-Static Stoneley Slowness from the estimate final Stoneley dispersion.

A well measurement system for producing an Quasi-Static Stoneley Slowness log and shear slowness anisotropy for a vertically transversely isotropic formation comprising:

• a downhole tool;
• a vehicle, wherein the downhole tool is attached by a conveyance to the downhole tool;
• and
• an information handling system operable to record a pressure wave at a receiver;
• determine a slowness-frequency range with an information handling system from the pressure wave;
• process a frequency-domain semblance;
• extract a Stoneley Dispersion;
• minimize a misfit between theoretical and the Stoneley Dispersion;
• and identify Quasi-Static Stoneley slowness from the Stoneley Dispersion.
