Oil depletion on some of the Russian deposits necessitates to formulate models which take into account the variation of deflected mode caused by chemical interactions between components of an underground fluid and the ...

© 2019 Elsevier B.V. This paper proposes a method for characterization of the two-phase displacement mechanisms (viscous fingering, capillary fingering, stable front, and crossover) in porous media. The approach is based ...

It was shown that the fractional dissolution of organic soil components based on elution from a column using an cluent with continuously increasing dissolving power can be used for characterizing the affinity of soil organic ...

The analyzed data of 3D structure investigation for the most low-temperature illite indicate that in smectite illitization at least two mechanisms can be involved, from which one is associated with biota activity and doesn't ...

This paper studies the low-temperature illitization of smectite in arid basins, where fresh sediments underwent drastic changes in redox potential. We examined Upper Permian sediments from Tatarstan and the Komi Republic, ...

An exact solution is obtained for the problem of the washing of a porous halfspace in a diffusion-free arrangement. An investigation is made of the characteristic features of mass transfer during the filtration of an active ...

The problem of the squeezing out of a solution from aggregates in a porous medium has been considered and investigated. A specific feature of the problem lies in taking account of the existence of two compaction zones in ...

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. The authors have developed a mathematical model of multiphase nonisothermal filtration with chemical reactions and phase transitions in deformable ...

The reasons for the technogenic decrease in the filtering capacity of oil reservoirs are considered. It is shown that the processes of transformation of the structure of argillaceous minerals are determining in this case. ...
