A Finite Difference Formulation of Biot's Equations for Vertically Heterogeneous Full Waveform Acoustic Logging Problems
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
In this paper we present a finite difference formulation for Biot's equations for wave
propagation in saturated porous media which vary in range and depth. One objective
of well logging petroleum exploration holes is to ...
Synthetic Acoustic Logs Over Bed Boundaries And Horizontal Fissures
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1986)
The finite difference method is used to predict the effects of wave propagation in boreholes with vertically varying elastic properties. Specifically horizontal interfaces between rock types (for example shales and sandstones) ...
Applications of Finite Difference Synthetic Acoustic Logs
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
Finite difference synthetic acoustic logs are suitable for studying wave propagation in vertically varying boreholes and in boreholes with continuously varying properties. Snapshots for the traditional smooth bore in a ...
Finite Difference Synthetic Acoustic Logs
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
Synthetic seismograms of elastic wave propagation in a fluid-filled borehole were generated using both the finite difference technique and the discrete wavenumber summation technique. The latter is known to be accurate for ...
