ABSTRACT:
A method is disclosed for predicting attenuation in real time while drilling using a portable continuous wave technology (CWT) tool to obtain amplitude spectra as a function of frequency for the cuttings at the rig site. Attenuation is predicted, and plotted as a function of frequency to monitor hydrocarbon content changes, fluid front moves, and pressure mapping or plotting attenuation as a function of depth to calibrate high resolution seismic data and interpret amplitudes for formation permeability determination.
