Reflection Moveout Inversion For Horizontal Transverse Isotropy: Accuracy And Limitation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1998)
Horizontal transverse isotropy (HTI) is the simplest azimuthally anisotropic model used
to describe vertical fracturing in an isotropic matrix. Using the elliptical variation of
P-wave normal-moveout (NMO) velocity with ...
Toward The Simulation Of Attenuation: Oscillatory Flow In Porous Rock
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1998)
Fluid flow in porous rock due to an oscillatory pressure gradient is simulated. We observe
distributions of density and velocity in the rock which point to viscous dissipation. We
will use this method to seek a deeper ...
Laboratory Study Of Frequency Dependent Streaming Potentials
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1998)
Frequency dependent streaming potentials were measured on a glass capillary, porous
filter, and a sample of Boise sandstone. The pore diameters for these three samples
range from 1 millimeter to 34 micrometers. The ...
Geostatistical Seismic Inversion Using Well Log Constraints
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
Information about reservoir properties usually comes from two sources: seismic data
and well logs. The former provide an indirect, low resolution image of rock velocity
and density. The latter provide direct, high ...
An Analysis Of Deconvolution: Modeling Reflectivity By Fractionally Integrated Noise
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
Reflection coefficients are observed in nature to have stochastic behavior that departs
significantly from the white noise model. Conventional deconvolution methods, however,
assume reflectivity to be a white noise ...
