  • Use of cuttings for real time attenuation prediction
    Patent number: 7040169
    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.

  • Use of cutting velocities for real time pore pressure and fracture gradient prediction
    Patent number: 6968274
    Abstract: Disclosed is a new method for providing accurate real time predictions of pore pressure and fracture gradient, at the rig site by determining the wave velocity from drill cuttings by a portable continuous wave technology (CWT) tool that measures drill cuttings at high resonant frequency and then using the velocity obtained in combination with the novel method of the present invention to arrive at accurate predictions for pore pressure and fracture gradient. The new technique offers real time pore pressure prediction at the rig site with small error margin that is not otherwise available using seismic, VSP, or check shot velocities in exploration.
