A New Method For Deriving Permeability From Borehole Stoneley Waves And Its Application In North Monagas Field Of Eastern Venezuela
With te proposed new advance technique for estimating permeability from borehole acoustic logs, a continuous frmation permeability profile can now be routinely obtained from full wave acoustic log. The success of this method lies in the separation of permeability related wave attributes from other effects unrelated to permeability. The new method uses an effective processing procedure to suppress noise and scattering effects in the data. It then performs wave modeling to account for wave attributes related to borehole and elastic property changes. Finally, it applies an inversion procedure to derive permeability from fluid-flow related wave attributes. The permeability obtained from this method has been compared with MRIL (Magnetic Resonance Imaging Log) derived permeability with remarkable correlation.
