Design and performing gravel pack using mechanical packer
Dejan Pavlov (2022)During the production of reservoir fluids, production of layer sand may occur due to one or a combination of several factors. These factors are the reservoir rock type, which can be unconsolidated sandstone, high depression value, increased water cut, turbulent flow regime of the reservoir fluid in the near-well zone, or hydraulic impacts that occur during the operation of the suck rod pump. This paper will include production wells completion with an improved Gravel Pack system, which enables more ...Dejan Pavlov. Design and performing gravel pack using mechanical packer, 2022

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...... work (W) divided by unit mass (m) (ton): w*= W '/m (1) The specific net power consumption (W'net) is defined as the difference between the power output and the power input: w*net= W 'output- w'input (2) where w output indicates the power produced by the system per unit mass. The power output ...
... injection started, the storage formation and expected CO» behavior was studied. The extra installations needed to handle the CO» coming from the capture unit were compressor trains including gas turbine drives, and an injection well. The CO» is compressed in stages to 80 bars and cooled to about 40%C ...
... the wellhead therefore limiting any corrosion and hydrate formation. To be able to handle 1 Mt CO per year, four parallel units were needed. Each unit has a fluid knockout drum, a compressor, a cooler and a gas turbine driver. Again, the compressor train with its gas turbine drive was designed ...John Nyame.

Oдређивање броја камиона за транспорт руде на површинском копу Шупља стијена
Грујичић Стефан (2024)Транспорт на површинским коповима се одвија паралелнпо са осталим процесима екаплоатације. Како не би долазило до непредвиђениих трошкова, потребно је усагласити све системе производње. Димензионисање адекватног транспортног система обезбеђује максималну продуктивност механизације и профитабилну експлоатацију. Чињеница да трошкови транспорта заузимају знатан део укупних трошкова иде у прилог томе да је одређивање потребног броја камиона за превоз откопаног материјала од великог значаја. У овом раду извршен је прорачун броја камиона потребног за транспорт руде од откопних етажа до дробилице на ...... Actions and Global Options Database Loading Unit .

Uporedna analiza stabilnosti završnih kosina površinskog kopa „Veliki Krivelj“
Mihajlo Topalović (2023)Površinski kop „Veliki Krivelj“ nalazi se u blizina grada Bora i u neposrednoj blizini sela Krivelj. Od 2018. godine je u vlasništvu kineske kompanije „Zijin“ koja ima udeo od 63% vlasništva celokupnog RTB-a Bor. Na površinskom kopu obavlja se masovna eksploatacija rude bakra opremom visokog kapaciteta. Za bušenje se koriste bušilice prečnika od 250 do 310 mm, a za utovar minirane rude i jalovine bageri čija je zapremina kašike 15 m3 i 22 m3. Za površinski kop „Veliki Krivelj“ ...Mihajlo Topalović.
