Alteration in composition of clays subjected to man-made impact Alvanya
Autor: Karine A. Alvanyan, Aleksandr V. Rastegaev, Tatyana Yu. Khludeneva
Publikováno v: Perm Journal of Petroleum and Mining Engineering, Vol 19, Iss 2, Pp 117-127 (2019)
Physical and chemical properties of clays depend on a group of factors determining energy potential on particle surface and on factors forming particle specific surface. Particle specific surface formation is directly related to issues of microaggr

The change of adhesion forces on the surface of the montmorillonite clay particles during high pressure processing
Autor: Maksim V. Fedorov, Igor V. Lunegov, Natalia A. Medvedeva, Mikhail F. Leonovich, Aleksander V. Rastegaev
Publikováno v: Perm Journal of Petroleum and Mining Engineering, Vol 19, Iss 1, Pp 26-38 (2019)
For the formation of the technological properties of clays, various methods have been developed: thermal, chemical, ultraviolet, mechanical and others. However, the issues of changing the properties of clays and clay particles compacted with high pre

Developing multilevel statistical models of determining bottom-hole flowing pressure in commercial oil well operations
Autor: Inna N. Ponomareva, Vladislav Ign. Galkin, Alexander V. Rastegaev, Sergey Vl. Galkin
Publikováno v: Revista Ingeniería UC, Vol 28, Iss 1 (2021)
One of the major tasks of monitoring oil production well operations is to determine bottom-hole flowing pressure (BHFP). The overwhelming majority of wells in the Perm krai are serviced using borehole pumps, which makes it difficult to take direct bo

On Spectral Asymptotics of the Sturm–Liouville Problem with Self-Conformal Singular Weight
Autor: U. R. Freiberg, N. V. Rastegaev
Publikováno v: Siberian Mathematical Journal. 61:901-912
Under study is the spectral asymptotics of the Sturm–Liouville problem with a singular self-conformal weight measure. We assume that the conformal iterated function system generating the weight measure satisfies a stronger version of the bounded di

On Spectral Asymptotics of the Sturm–Liouville Problem with Self-Conformal Singular Weight with Strong Bounded Distortion Property
Autor: U. R. Freiberg, N. V. Rastegaev
Publikováno v: Journal of Mathematical Sciences. 244:1010-1014
Spectral asymptotics of the Neumann problem for the Sturm–Liouville equation with singular selfconformal weight measure is considered under the assumption of a stronger version of the bounded distortion property for the conformal iterated function

Calculation of Graded Viscosity Banks Profile on the Rear End of the Polymer Slug
Autor: F. L. Bakharev, N. V. Rastegaev, Alexander V. Kalyuzhnyuk, Sergey Tikhomirov, Aleksanr Enin, Yulia Petrova, Andrey Groman, Konstantin M. Kalinin
Publikováno v: Day 1 Tue, October 12, 2021.
One of the motivations for EOR methods is the possible instability of the front between phases with high contrast of mobility. Highly viscous polymer slug partially solves the problem by stabilizing the front between water and oil. During further wat

Peculiarities of ground microseismic monitoring of HF with partial deepening of sensors under the low velocity zone and assessment of the reliability of the results obtained for the well of LUKOIL-PERM LTD
Autor: I. A. Chernykh, I.R. Sharapov, A. V. Rastegaev, V.A. Ryzhov, I.N. Ponomareva, S.A. Feofilov, A.Y. Milin
Publikováno v: Horizontal Wells 2021.
Summary The deepening of the sensors of the surface locating system under the low-velocity zone compensates for the influence of inaccuracy in the knowledge of the velocity model in the upper part of the section, reduces the level of registered surfa
