PORE CHANNELS DISTRIBUTION DENSITY BY THE WESTERN SIBERIA RESERVOIR ROCK SIZES

X-ray microtomography application in pore space reservoir rock.

Characterization of porosity in carbonate rocks is important in the oil and gas industry since a major hydrocarbons field is formed by this lithology and they have a complex media porous. In this context, this research presents a study of the pore space in limestones rocks by x-ray microtomography. Total porosity, type of porosity and pore size distribution were evaluated from 3D high resolutio...

Distribution of Yellow Wagtail Forms Motacilla flava – Complex in the North of Western Siberia, Russia

Abstract: On the basis of the materials obtained from the studies carried out from 2000 to 2015, we present the data on distribution of the Yellow Wagtail forms in the north of Western Siberia, i.e. within the overlapping boundaries of the ranges of a complex set of several polytypical forms – Motacilla flava sensu lato. Four forms have been identified here: two forms from the group of Western ...

Tickborne Pathogen Detection, Western Siberia, Russia

Ixodes persulcatus (n = 125) and Dermacentor reticulatus (n = 84) ticks from Western Siberia, Russia, were tested for infection with Borrelia, Anaplasma/Ehrlichia, Bartonella, and Babesia spp. by using nested polymerase chain reaction assays with subsequent sequencing. I. persulcatus ticks were infected with Borrelia burgdorferi sensu lato (37.6% +/- 4.3% [standard deviation]), Anaplasma phagoc...

spatial distribution of gmelinoides fasciatus steb. in thermally polluted water (belovo reservoir, southwest siberia)

gmelinoides fasciatus (stebbing, 1899) is a baikal endemic amphipod that has recently become widespread in eurasia. this species accidentally entered the cooling reservoir of the belovo power plant and became successfully naturalised there. this study describes the peculiarities of g. fasciatus distribution in reservoir sites with different thermal regimes and analyses the environmental factors...
