  • STUCK PIPE OPTIMIZATION USING DUELLIST ALGORITHM 
    Biyanto, T. R.; Cordova, H.; Matradji; Anggrea, T. O.; Suryowicaksono, H.; Irawan, S. (IOP Publishing Ltd, 2021)
    Stuck pipes are one of the most serious drilling problems, stuck pipes can cost the oil industry hundreds of millions of dollars per year. One way to avoid the risk of a stuck pipe is to predict the condition of a stuck ...
  • A study of the performance of the LSWA CO2 EOR technique on improvement of oil recovery in sandstones 
    Pourafshary, Peyman; Al-Abria, H; Mosavat, Nader; Al Hadhrami, H (ELSEVIER, 2018-07-05)
    Low salinity water is an emerging enhanced oil recovery (EOR) method that causes wettability alteration towards a favorable state to reduce residual oil saturation, while water alternating gas (WAG) is a proven EOR process ...
  • SYNTHESIS, CHARACTERIZATION, AND ASSESSMENT OF A CEO2@NANOCLAY NANOCOMPOSITE FOR ENHANCED OIL RECOVERY 
    Javad Nazarahari, Mohammad; Khaksar Manshad, Abbas; Moradi, Siyamak; Shafiei, Ali; Abdulazez Ali, Jagar; Sajadi, S. Mohammad; Keshavarz, Alireza (MDPI, 2020-11-17)
    In this paper, synthesis and characterization of a novel CeO2/nanoclay nanocomposite (NC) and its effects on IFT reduction and wettability alteration is reported in the literature for the first time. The NC was characterized ...
  • The changing water cycle: Burabay National Nature Park, Northern Kazakhstan 
    Yapiyev, Vadim; Sagintayev, Zhanay; Verhoef, Anne; Kassymbekova, Anara; Baigaliyeva, Marzhan; Zhumabayev, Dauren; Malgazhdar, Daniyar; Abudanash, Damira; Ongdas, Nurlan; Jumassultanova, Saltanat (Wires Water, 2017)
    Water resources in Central Asia are scarce, so complicated issues arise from this. Kazakhstan is a Central Asian landlocked country, which has mostly closed drainage basins, characterized by endorheic lakes that do not ...
  • Top soil physical and chemical properties in Kazakhstan across a north-south gradient 
    Yapiyev, Vadim; Gilman, Charles P.; Kabdullayeva, Tolganay; Suleimenova, Akmaral; Shagadatova, Aizhan; Duisembay, Azat; Naizabekov, Sanzhar; Mussurova, Saule; Sydykova, Kamilya; Raimkulov, Ilyas; Kabimoldayev, Ilyas; Abdrakhmanova, Ainagul; Omarkulova, Symbat; Nurmukhambetov, Dastan; Kudarova, Aliya; Malgazhdar, Daniyar; Schönbach, Christian; Inglezakis, Vassilis (SCIENTIFIC DATA, 2018-11-13)
    Kazakhstan’s soil properties have yet to be comprehensively characterized. We sampled 40 sites consisting of ten major soil types at spring (wet) and late-summer (dry) seasons. The sample locations range from semi-arid to ...
  • TOWARD REDUCING SURFACTANT ADSORPTION ON CLAY MINERALS BY LIGNIN FOR ENHANCED OIL RECOVERY APPLICATION 
    Abbas, Azza Hashim; Pourafshary, Peyman; Sulaiman, Wan Rosli Wan; Jaafar, Mohd Zaidi; Nyakuma, Bemgba B. (ACS Omega, 2021-07-12)
    The significant loss of surfactants during reservoir flooding is a challenge in oil field operations. The presence of clay minerals affects the surfactant performance, resulting in surfactant losses. This is because ...
  • Uncertainty quantification of rock quality designation at the Gazestan phosphate deposit 
    Madani, Nasser; Yagiz, S.; Adoko, A.C.; Battalgazy, Nurassyl (Geometallurgy Conference 2018, Back to the Future Cape Town, (6-8 August 2018). The Southern African Institute of M ining and Metallurgy, 2018-08-06)
    Several geomechanical variables reflect the characteristics of rock masses and in recent years have been considered as the geometallurgical responses in the mining industry. These variables have a great effect on the ...
  • UTILIZING ULTRASONIC WAVES IN THE INVESTIGATION OF CONTACT STRESSES, AREAS, AND EMBEDMENT OF SPHERES IN MANUFACTURED MATERIALS REPLICATING PROPPANTS AND BRITTLE ROCKS 
    Bou-Hamdan, Kamel Fahmi; Abbas, Azza Hashim (Arabian Journal for Science and Engineering, 2021-12-02)
    In the oil and gas industry, hydraulic fracturing (HF) is a common application to create additional permeability in unconventional reservoirs. Using proppant in HF requires understanding the interactions with rocks such ...
