The article presents the results of analysing geological structure Famennian deposits (Devonian) in Perm Region. Numerical modelling distribution inhomogeneous stress field near well was performed for two considered types perforation. With regard geometry forming perforation channels, numerical finite element models near-wellbore zones were created considering slotted and cumulative It is ascer...

Peracarida (e.g. woodlice and side-swimmers) are, together with their sister-group Eucarida krill decapods), the most speciose group of modern crustaceans, suggested to have appeared as early Ordovician. While eucarids' incursion onto land consists mainly freshwater littoral grounds, some peracarids evolved fully terrestrial ground-crawling ecologies, inhabiting even our gardens in temperate re...

Abstract The Devonian/Carboniferous Boundary (DCB) interval is associated with mass extinction, isotope excursions and a short glacial episode. This study investigates how boundary extinction environmental change expressed in the high-palaeolatitudinal record of Bolivian Altiplano (western Gondwana). A latest Devonian early Carboniferous section has been investigated using sedimentology, palyno...
