Zircon as a Source of Genetic Information in Upper Riphean Terrigenous Deposits of Southern Timan

open access: yesThe Bulletin of Irkutsk State University. Series Earth Sciences, 2023
Zircon is an important source of genetic information. The purpose of the research is a detailed study, identification of diagnostic features, and determination of the evolution of the composition of zircon, which will make it possible to establish the sources of clastic material and the conditions for the formation of the paleontologically mute ...

THERMODYNAMIC RIPHEAN-PHANEROZOIC EVOLUTION OF THE UPPER GEOSPHERES: ATMOSPHERE, EARTH’S CRUST, HYDROSPHERE AND BIOSPHERE [PDF]

open access: yesGeological Journal, 2020
A new concept of thermodynamic Riphean-Phanerozoic evolution of upper geospheres: atmosphere, earth’s crust, hydrosphere and biosphere is presented. This evolution from Riphean to Phanerozoic is determined by the consistent cooling of the earth’s surface.

A fishtail well design for cyclic steam injection—A case study from Yarega heavy oil field in Russia

open access: yesEnergy Science &Engineering, Volume 7, Issue 6, Page 2437-2455, December 2019., 2019
The joint application of cyclic steam injection technology with fishtail wells assists in reducing the travel time the mobilized oil takes to arrive at a well perforation. Our results demonstrate that the synergy between these two strategies can further improve recoveries in heavy oil reservoirs. In addition to the technical advantage of this strategy,
