Fracture compliance measurements in synthetic fractured media
SEG Technical Program Expanded Abstracts 2013, 2013Ultrasonic velocities were measured on a stack of synthetic material (plexiglass plates), at low (90/120 kHz, long wavelength range: 12-23 mm) and high (431/480 kHz, short wavelength range: 1-6 mm) frequencies. The plexiglass plates were pressed together with uniaxial normal stress.

Seismic inversion for geologic fractures and fractured media
GEOPHYSICS, 2017Amplitude variation with offset (AVO) inversion attempts to use the available surface seismic data to estimate the density, P-wave velocity, and S-wave velocity of the earth model. Under linear slip interface theory, synthetic seismograms for models with fractures prove that fractures are also reflection generators.

Fracture-Liquid Transmissibility in Fractured Porous Media
SPE Reservoir Engineering, 1994Summary The flow of oil phase in the gas/oil two-phase region in fractures is a key to production performance of fractured petroleum reservoirs where gravity drainage is the dominant mechanism. In this study, data on a set of experiments that center on flow of the oil phase in the fractures are presented.

Diffusion of a Contaminant in Fractured Porous Media
Health Physics, 1985A theoretical model is developed for diffusion from a finite source of buried contaminant through a porous medium containing a fracture that reaches to the atmosphere. Important quantities are shown to be the burial depth, source width and fracture width, the soil porosity, the diffusion coefficients in the soil and the (air-filled) fracture, and the ...
