A case of two-dimensional motion of thermal waters under the action of two wells comprising a spaced dipole is investigated on the basis of a reservoir model in the form of a heterogeneous structure consisting of disjoint continua, one of which is em

The solution is presented for the problem on oil percolation in a reservoir at the present and time-varying pressure difference between the injection and production wells. The area of water blocking under capillary pressure in the well bottom zone is

A mathematical model of blood circulation in human lower limbs is proposed. The model is based on the laws of motion (filtration) of a viscous fluid in a heterogeneous medium consisting of two or more interpenetrating continua. It is assumed that the

The problem on oil filtration in the reservoir model with the preset differential pressure harmonically varying in time on its faces is solved. Hysteresis effects of capillary pressure under change in the direction of fluid expulsion are considered.

In a previously published mathematical model of blood circulation in the cerebral cortex, it was assumed that the circulatory system of the brain consists of a distribution network of relatively large arteries and a collector network of veins similar

A mathematical model for hydraulic fracturing is proposed. The model is based on the presentation of the fractured portion of the stratum adjacent to the well as a heterogeneous fractured porous medium. Assumptions usually used in the theory of elast

Two schemes of closed circulation of thermal waters are considered. The first scheme is filtration in a single stratum. In the second scheme, the flow in a formation with a weakly permeable bottom is considered. The effective for designers formulas a

Penetration of distilled water into a clay soil sample saturated by a sodium chloride solution is experimentally studied. Changes in filtration characteristics of soil due to penetration of fresh water and swelling of clay particles, as well as due t
