Fast Inversion Of Formation Permeability From Stoneley Wave Logs Using A Simplified Blot-Rosenbaum Model
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)This paper describes a fast algorithm for estimating formation permeability from Stoneley wave logs. The procedure uses a simplified Biot-Rosenbaum model formulation. The input to the inversion is the Stoneley wave ... -
Experimental Study Of The Flexural Waves In The Fractured Or Cased Borehole Model
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)The ultrasonic logging is performed with dipole transducers in aluminum and lucite borehole models to study the propagation of the flexural waves in a fractured or cased borehole. The experimental results show that the ... -
Acoustic Wave Propagation In And Around A Fluid-Filled Borehole Of Irregular Cross-Section
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)Boreholes with 10% or more ellipticity are not uncommon. In this paper, we consider the coupling of an incident elastic wave into a borehole of irregular cross-section and investigate the cross-mode coupling phenomenon ...
