  • 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 ...
