  • Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)

    Nikoleta Aleksić, Aleksandar Kostić, Miloš Radonjić (2021)
    This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ...

  • Утечњени природни гас (УПГ) – технологија производње и регасификације

    Јована Милетић (2024)
    У овом раду истраживање је обухватило сагледавање карактеристика утечњеног природног гаса као извора енергије и његове улоге у савременој расподели потрошње енергије на глобалном и европском нивоу. Проучени су елементи тржишта утечњеног природног гаса, сектори коришћења, транс-портне руте и количине испорука. Сагледан је пут природног гаса од лежишта до корисника преко утечњавања и транспорта у резервоарима, са посебним акцентом на технологијама производње и регасификације. Објашњено је пречишћавање сировог природног гаса ради уласка у процес утечњавања, процеси утешњавања и настојања ...

  • 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 ...
