Sandstone Pore Aspect Ratio Spectra from Direct Observations and Velocity Inversion
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)Measurements of pore shapes from Scanning Electron Microscope (SEM) images for three sandstone samples (the Navajo Sandstone, the Weber Sandstone, and the Kayenta Sandstone) are compared to the aspect ratio spectra ... -
Physical Properties of a Set of Sandstones, III: the Effects Of Fine Grained Pore Filling Material on Compressional Wave Velocity
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)We have used aspect ratio modeling to explain the measured compressional wave velocities of twenty different dry sandstone samples with varying clay contents at a single confining pressure of 0.5 kbar. Velocities of the ... -
Laboratory Measurements of Attenuation in Rocks at Ultrasonic Frequencies
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)The spectral ratio method is used to calculate the quality factor (Q) in porous rock samples at ultrasonic frequencies (0.3 - 1.5 MHz). The data were collected using the pulse transmission technique with aluminum used ...
