  • Application of Gel for Water Shutoff: A Case Study of Kelebija Oil Field

    Irina Zahirovic, Petar Skrobonja, Dušan Danilović (2022)
    This paper focuses on the results of water shutoff operations using DSGA polymer gel in the Kelebija oil field. The methodology of candidate wells selection and the manner of performing the operation will also be included. The Kelebija oil field is characterized by a complex reservoir system with heterogeneous layers of different permeability and dual porosity, which led to the early breakthrough of water. For the last 25 years, average water cut was above 90%. Implementation of water shutoff ...

  • The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments

    Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)
    The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...

  • 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 ...

  • The influence of alkyl polyglucosides (and highly ethoxylated alcohol boosters) on the phase behavior of a water/toluene/technical alkyl polyethoxylate microemulsion system

    The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering ...

  • Selection of Artificial Lift Methods: A Brief Review and New Model Based on Fuzzy Logic

    Miroslav Crnogorac, Miloš Tanasijević, Dušan Danilović, Vesna Karović Maričić, Branko Leković (2020)
    Artificial lift methods have applications in oil wells where oil production is no longer possible due to natural reservoir energy, so this necessary energy is added by introducing lift methods. In order to achieve optimum production, the selection of an artificial lift method is very important. This paper uses fuzzy logic as a mathematical and conceptual model for selection of the optimal artificial lift method. The outcome or IF-THEN rules, as the central part of the model, is based ...

  • Microemulsion with aromatic oil as cleaner media for electropolymerisation

    M. Ilić, F.-H. Haegel, S. Zlatanovic, N. Potkonjak, B. Simonovic (2005)
    Abstract Microemulsion polymerization is widely used as a cleaner alternative way to prepare intrinsically conductive polymers. We studied isothermal phase diagrams for microemulsions of the electropolymerizable heterocyclic aromatic oil 3,4-ethylenedioxythiophene (EDOT), aqueous LiClO4 solution and alkyl polyethoxylate. Our specific goal was to assess the effect of LiClO4 salt on the phase behaviour. The phase behaviour was characterized by stepwise titration and microscopic analyses. Here we found that the increase of the concentration of LiClO4 salt shifts the microemulsion region ...
