A study of the reservoir characteristics Tournaisian formation in Yablunivske oil and gas condensate filed shows that pore structure this area is complex permeability varies widely. Based on logging response characteristics, core analysis data curves GR, DT normal resistivity curves, mud content, porosity, permeability, bound water saturation parameters were calculated by statistical regression...

conodonts of khoshyeilagh formation, the most complete section of devonian rocks in the alborz mountains, northern iran, has been studied, and subspecies of the genera icriodus, bipennatus, polygnathus, pelekysgnathus, ancyrodella, palmatolepis, bispathodus, scaphignathus, clydagnathus, gnathodus, scaliognathus and dollymae have been obtained from the studied section. the faunas indicate an eif...

Abstract The Protocanites Beds of the Black Forest Massif (Germany) form an important lithostratigraphic key bed, as index fossils contained in this formation enable correlation within large areas internal zone central Variscan Belt Europe. Furthermore, provides significant information on geodynamic evolution Moldanubian Zone. stratigraphic age has been a subject controversy past; Devonian to V...

Early Carboniferous coiled nautiloids from North Africa are virtually unknown. An assemblage of nine species, all the family Trigonoceratidae, Dalle à Merocanites (Tournaisian-Viséan boundary interval) Timimoun in western Algeria is described, being most diverse nautiloid known but much less than time-equivalent assemblages Belgium and Ireland. The consists species Maccoyoceras pentagonum sp. n...
