Geomechanics and Fluidodynamics

This monograph focuses on adequate mathematical models of the deformation and failure of geological materials, and on corresponding experimental work. Borehole stability and water, gas and oil reservoir states are studied, and the actions of underground explosion and hydrofracture are described. Gas-condensate flows, permafrost and gas-hydrated soil changes, electrokinetic effects and dilatancy are considered. The theory of seismic waves, including their nonlinear evolution, is given. The lithosperic structure is discussed with respect to rock properties under high thermodynamic conditions. The internal boundaries of the lithosphere are interpreted physically, and the fluid dynamics of the Earth are connected to convection and mass-transfer phenomena. The basic concepts of continental drift and continental development are related to tectonic stress transmission, release at earthquake events and modulation due to Solar System oscillations. The theory of tectonic-wave deformation is developed. Necessary explanations are given against a background of continuum mechanics and mathematical physics. This is a textbook aimed at students specializing in such fields as oil and gas recovery, geophysics, the mining industries, explosions, and ecology.
