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.

Parallel Bidirectionally Pretrained Taggers as Feature Generators
In a setting where multiple automatic annotation approaches coexist and advance separately but none completely solve a specific problem, the key might be in their combination and integration. This paper outlines a scalable architecture for Part-of-Speech tagging using multiple standalone annotation systems as feature generators for a stacked classifier. It also explores automatic resource expansion via dataset augmentation and bidirectional training in order to increase the number of taggers and to maximize the impact of the composite system, which ...Ranka Stanković, Mihailo Škorić, Branislava Šandrih Todorović.

Facies analyses, biostratigraphy and radiometric dating of the Lower-Middle Miocene succession near Zajecar (Dacian basin, eastern Serbia)
Ljupko Rundić, Nebojsa Vasić, Miodrag Banješević, Dejan Prelević, Violeta Gajić, Bojan Kostić, Jelena Stefanović (2020)Седиментна сукцесија између доњег и средњег миоцена и складан тј. дискордантан однос између језерско-континенталних наслага (нпр. DLS, SLS) и баденских морских седимената представља једну од занимљивих тема. У овом раду смо проучавали пет истражних бушотина (источна Србија) и анализирали главни фацијални образац, биостратиграфске карактеристике миоценске сукцесије и применили U-Pb радиометријско датирање вулканских туфова интерстратификованих у седиментној серији са слојевима угља (бушотина NRKR-17002). Добиjeна је конкордија старост од 16,9 ± 0,2 милиона година за сва анализирана зрнца циркона без наследних ...Ljupko Rundić, Nebojsa Vasić, Miodrag Banješević, Dejan Prelević, Violeta Gajić, Bojan Kostić, Jelena Stefanović.
