Latest Patents

J Adam Donald holds a patent for a method titled "Method for Characterizing Shear Wave Formation Anisotropy." This patent describes a technique for characterizing shear wave anisotropy in geological formations. The method involves obtaining crossed-dipole waveforms from a borehole that penetrates the formation over a range of depths and frequencies. It includes determining far-field slowness in both fast-shear and slow-shear directions using low-frequency portions of the waveforms. Additionally, it assesses near-wellbore slowness in these directions using high-frequency portions. The method allows for the identification of intrinsic and stress-induced anisotropy at selected depths based on the slowness measurements.
