... medium theory, and its avoidance resolves that inconsistency. The corrected formula ( e.g. Brown and Korringa, 1975) is fully consistent with effective medium theory, for any micro-geometric model. upstream oil & gas elasticity logical error additional parameter pore pressure effective...

.... Using the targeted method, which does not require segmentation, voxels that capture a mixture of pore and grain are assigned the properties of the mixture by means of an effective medium theory. The targeted method, therefore, does not require resolving individual grain boundaries, and lower resolution...

... with these effective medium theories are used as models to simulate the propagation of ultrasonic waves. All effective medium theories applied to the rock as a whole significantly over predicted P wave velocity from 23% to 75%. Segmentation predicted a velocity 64% higher than the lab measurement. In all scenarios...

... Summary We discuss and address two questions for effective medium theories in fractured, porous media: How the pores and cracks interactions could affect the elastic response and seismic anisotropy? And can we physically characterize the pores and cracks interactions? We first use Biot...

... using effective medium theory. Effective Medium Modeling takes into consideration the elastic properties of the sediments and is considered as one of the most efficient rock physics models. This method is further used to determine the porosity and hydrate logs at the NGHP-01-05 site of Krishna Godavari...

...-partitioning techniques to assign grain moduli, and employ effective medium theories based on a relation between Xray-CT density and porosity to assign contact moduli between grains. We numerical derive the macroscopic effective elastic moduli of several reservoir rocks, and study their sensitivity...

... wave scattering is strongly dependent on the inhomogeneous scale of medium. Ray theory (Snell s law) best describes wave propagation when the scale of heterogeneity is larger than seismic wavelength (high frequency or short-wavelength approximation). Effective medium theory (e.g., Backus, 1962...
