Results predicted by the "exact" numerical solution, including load relaxation, pore pressure, stresses and strains, are compared to an approximate analytical solution that incorporates the assumptions of simple beam theory.
Generally, these measurements are made at different stresses, pore pressures and temperatures than are found in the subsurface.
Expressions for the pore fluid pressure, stresses and displacements in the Laplace domain are derived analytically.
Because we have limited our wellbore design and analysis in this study to a single vertical well, the magnitude and orientation of principal stresses, pore pressure and well orientation are assumed to be consistent at a given depth.
The modified pore pressure and stresses around a borehole in shale are obtained by solving the porothermoelastic field equations in generalized plane strain.
In Part B, predictions for local field variables, such as temperature, relative humidity, pore water pressure, stresses and displacements at selected points in the bentonite, and global variables, such as the total input power to the heaters were required.
Many papers in the literature present studies of the interaction of sea waves, structures, and soil; however, most of these studies focus on the pore pressures and stresses in the soil around structures.
The numerical comparative analyses in the present paper examine the influence of material anisotropy of poromechanical parameters and thermal properties, which embody in porothermoelastic-osmosis-filtration model and common porothermoelastic one, on the thermally induced pore pressure and stresses.
Still, process induced imperfections, i.e. micron sized pores and residual stresses upon processing, need to be considered for future application, e.g. in the aerospace and biomedical sectors.
Pore pressure-stress analyses in stress-sensitive reservoirs investigate interactions between the in-situ stress and fluid flow; these interactions help or resist production, or conclude surface subsidence during production.
