Formation of metallic magnetic clusters in a Kondo-lattice metal: Evidence from an optical study [PDF]

open access: yes, 2012
Magnetic materials are usually divided into two classes: those with localised magnetic moments, and those with itinerant charge carriers. We present a comprehensive experimental (spectroscopic ellipsomerty) and theoretical study to demonstrate that these

The Bazhenov Formation Rocks Wettability by NMR

open access: yesProceedings, 2017
Summary The petrophysical characteristics determination of the Bazhenov formation rocks is very difficult. Previously used adsorption method to study the wettability, due to the large organic matter content in the mineral matrix, showed a high degree of hydrophilicity.

Feasibility of the Bazhenov Formation Reservoir Hydrodynamic Model

open access: yesУспехи кибернетики / Russian Journal of Cybernetics, 2021
Опыт изучения нефтяных месторождений, приуроченных к отложениям баженовской свиты, показывает, что продуктивность нефтенасыщенных пластов является существенно неоднородной как по площади, так и по разрезу месторождения. Выявление зон повышенной продуктивности в отложениях баженовской свиты является одной из первоочередных задач по вовлечению в ...

Assessment of Mesozoic-Kainozoic climate impact on oil-source rock potential (West Siberia) [PDF]

open access: yes, 2015
Based on paleotemperature modeling, the evaluation of the effect of Neo-Pleistocene permafrost rock thickness on geothermal regime of the Bazhenov deposits has been performed. It has been stated that permafrost about 300 m in thickness must be considered

Bazhenov formation phosphate containing interlayers as potential collectors

open access: yesMoscow University Bulletin. Series 4. Geology, 2016
Possible reservoir type of Bazhenov formation relative to the intervals with increased content of phosphate is described in the resent work. It is shown that phosphate formations have highly connected pore space, porosity may achieve values up to 14%. These rocks also have explicit geochemical characteristics of oil reservoir rocks in comparison with ...

Vortex nucleation and evolution in parametric wave mixing [PDF]

open access: yes, 1999
We predict a variety of new phenomena, that includes the spontaneous nucleation of multiple vortex twins, vortex rotation and drift, vortex-antivortex interaction and annihilation, and formation of quasi-aligned patterns of single-charge vortices.
