Productivity improvement with use of beam gas compressor: pilot test in Southeastern Europe mature field
Most of the wells in the oilfield Turija are operating with sucker rod pumps, where casing pressure at around 15 bar, and with marginal production rates. The high value of casing pressure indicates high pressure on the face of the formation and depends directly on well productivity. In addition, with increasing value of the casing pressure gas column in the annulus is moving the dynamic fluid level near pump intake and more gas is entering the pump, it results ...beam gas compressor, BGC, increase productivity, sucker rod pump, SRP, mature field, artificial lift, production optimisationBojan Martinović, Dušan Danilović, Branko Grubač, Robert Fadiga.

Reconstruction of the Tethys' waning in the Balkans: New insights from Upper Cretaceous igneous formations and zircon provenance data
... Neotethys represent a subject of ongoing debate, particularly concerning the waning stages of the Tethyan ocean(s) in the Balkans and the timing of the Europe-Adria collision. While some researchers propose that this collision occurred in the Late Jurassic', others argue it took place at the end of the ...

The lost freshwater goby fish fauna (Teleostei, Gobiidae) from the early Miocene of Klinci (Serbia)
Freshwater gobies played an important role in the Miocene paleolakes of central and southeastern Europe. Much data have been gathered from isolated otoliths, but articulated skeletons are relatively rare. Here, we review a rich assemblage of articulated gobies with abundant otoliths in situ from the late early Miocene lake deposits of Klinci in the Valjevo freshwater lake of the Valjevo-Mionica Basin of Serbia. The fauna was originally described by Anđelković in 1978, who noted many different fishes, including one ...Katarina Bradić-Milinović, Harald Ahnelt, Ljupko Rundić, Werner Schwarzhans.

Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia
Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (East ern Serbia). Both the morphological and metric characteristics of the teeth are consis tent with the attribution to S. hundsheimensis. Unfortunately, the rhinoceros material originated from an uncertain geological context, so there is no ......
