  • 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 ...

  • Design and drilling of wells in formations with high pressure

    Vojin Solomun (2024)
    Objectives of this Thesis are to: - Develop an awareness of the challenges presented from elevated temperatures and pressures in well construction. - Learn the key differences between ―normal‖ condition wells and HPHT wells. - Understand some of the indicators of thermal- and pressure-related problems. - Understand the responses which may be made to mitigate high pressure and high temperature ,,HPHT‘‘ challenges while drilling wells. HPHT wells are an unavoidable consequence of the ever expanding search for oil and gas resources around the world. As wells are ...

  • Analysis of performed workover in wells

    Momir Radovanović (2023)
    This paper will describe and explain workover that are carried out in the wells, the types of these works and their division according to the scope of the works that are carried out, the tools and operations that are most often used and performed in order to enable the well and return it to production. Since the range of operations and tools that are used in workover is very wide, the most common operations and tools used are listed and ...

  • Design of a sucker rod pumping system

    Ana Ponoćko (2024)
    For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs. The first part of the paper presents the underground and surface equipment of the rod pump and describes the operation of the entire system. The ...

  • 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 ...

  • Cement Slurries for Drilling Fluid Loss Control

    Miljan Stojiljković (2022)
    In the oil industry cements are clasiffied according to API standard. API cements are made for oil drill wells and are made the same way as the Portland cement is made, from the same compounds, but in different relations. These cements are projected to fulfill different conditions in oil drill wells. Different additives are added to change certain cement properties. Additives used in oil industry affect hardening time, cement density and viscosity change. Cement represents basic tool for closing ...

  • Savremeni pristup rešavanja problema industrijskog otpada

    Mariја Bošković (2024)
    Rad ukazuje na savremene metode rešavanja problema industrijskog otpada, sa posebnim fokusom na pećnu prašinu koja nastaje tokom metalurških procesa, poput proizvodnje čelika u elektrolučnim pećima. U radu se detaljno razmatra hemijski sastav pećne prašine, koja sadrži teške metale poput cinka, olova i kadmijuma, i naglašavaju ekološki izazovi koje predstavlja njeno zbrinjavanje. Takođe, analiziraju se metode tretmana i valorizacije pećne prašine, uključujući pirometalurške i hidrometalurške procese, pri čemu je poseban akcenat stavljen na reciklažu cinka iz pećne prašine. Dalje, ...
