A study of wave propagation in fractured porous media saturated by two immiscible fluids is presented, based on the double-porosity concept. The macroscopic constitutive relations and mass and momentum balance equations are obtained by volume averaging the microscale balance and constitutive equations, and assuming small deformations. Momentum transfer terms are expressed in terms of intrinsic and relative permeabilities assuming the validity of Darcy's law in fractured porous media. In the simplest case, the final set of governing equations reduce to Blot's equations containing the same parameters as Blot and Willis. Then, we demonstrate the existence of four compressional waves and one rotational wave. The first and third compressional waves are analogous to the fast and slow compressional waves in Blot's theory. The second compressional wave arises because of fractures, whereas the fourth compressional wave is associated with the pressure difference between the fluid phases in the porous blocks. All compressional waves, except the first, are diffusive-type waves, i.e., highly attenuated and nonexistent at low frequencies.

Wave Propagation in Poroelastic Media Saturated by Two Fluids Tuncay, Kağan (ASME International, 1997-6-1) <jats:p>A theory of wave propagation in isotropic poroelastic media saturated by two immiscible Newtonian fluids is presented. The macroscopic constitutive relations, and mass and momentum balance equations are obtained by volume averaging the microscale balance and constitutive equations and assuming small deformations. Momentum transfer terms are expressed in terms of intrinsic and relative permeabilities assuming the validity of Darcy’s law. The coefficients of macroscopic constitutive relations are expr...
Body waves in poroelastic media saturated by two immiscible fluids Tuncay, Kağan (American Geophysical Union (AGU), 1996-11-10) A study of body waves in elastic porous media saturated by two immiscible Newtonian fluids is presented. We analytically show the existence of three compressional waves and one rotational wave in an infinite porous medium. The first and second compressional waves are analogous to the fast and slow compressional waves in Blot's theory. The third compressional wave is associated with the pressure difference between the fluid phases and dependent on the slope of capillary pressure-saturation relation. Effect o...
Body waves in fractured porous media saturated by two immiscible Newtonian fluids Tuncay, Kağan (Springer Science and Business Media LLC, 1996-06-01) A study of body waves in fractured porous media saturated by two fluids is presented. We show the existence of four compressional and one rotational waves. The first and third compressional waves are analogous to the fast and slow compressional waves in Riot's theory. The second compressional wave arises because of fractures, whereas the fourth compressional wave is associated with the pressure difference between the fluid phases in the porous blocks.

Wave propagation in fractured porous media Tuncay, Kağan (Springer Science and Business Media LLC, 1996-06-01) A theory of wave propagation in fractured porous media is presented based on the double-porosity concept. The macroscopic constitutive relations and mass and momentum balance equations are obtained by volume averaging the microscale balance and constitutive equations and assuming small deformations. In microscale, the grains are assumed to be linearly elastic and the fluids are Newtonian. Momentum transfer terms are expressed in terms of intrinsic and relative permeabilities assuming the validity of Darcy's...
Uncertainty quantification by using stochastic approach in pore volume calculation for geothermal reservoir Gürel, Emrah; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2015) This study will present the application of a stochastic approach and experimental design techniques to a geologic system in order to quantify the uncertainty of pore volume estimations for a liquid dominated high temperature geothermal reservoir. The pore volume is a key element when defining the total resource available in the field. Alasehir geothermal reservoir pore volume uncertainty has been assessed. The uncertainties being addressed include geometry (top of reservoir and base of reservoir), reservoir...
