Webproperly estimate the Biot-Willis coefficient, we must determine the petrophysical properties from which components of the rock mass such as its pore space, frame and solid phase can be assembled from its constituent parts. In this study, we estimate the Biot-Willis coefficient from seismic data via a rock physics inversion. WebPoromechanics. Poromechanics is a branch of physics and specifically continuum mechanics and acoustics that studies the behaviour of fluid-saturated porous media. [1] …

WebMay 28, 2024 · Understanding rock behaviour as a function of pore pressure and confining pressure is crucial for petroleum and geomechanical analysis. Indeed, deformation and local stress variations within hydrocarbon reservoirs and their surroundings occur due to pore pressure changes. Theoretically, pore pressure changes coupled with stress variations in … WebThe Biot-Willis coefficient is a key component associated with the effective stress field, where it represents the proportion of fluid pressure that counteracts the confining stress. … WebABSTRACT Within the Biot poroelasticity theory, the effective pressure coefficient for the bulk volume of a fluid-saturated rock and the Biot coefficient are one and the same … sonic battle r prototype v3
