Porosity model and pore evolution of transitional shales: an example from the Southern North China BasinElsevier BV - Tập 17 - Trang 1512-1526 - 2020
Xiao-Guang Yang, Shao-Bin Guo
The evolution of shale reservoirs is mainly related to two functions: mechanical compaction controlled by ground stress and chemical compaction controlled by thermal effect. Thermal simulation experiments were conducted to simulate the chemical compaction of marine-continental transitional shale, and X-ray diffraction (XRD), CO2 adsorption, N2 adsorption and high-pressure mercury injection (MIP) w...... hiện toàn bộ
Experimental investigation into Fe3O4/SiO2 nanoparticle performance and comparison with other nanofluids in enhanced oil recoveryElsevier BV - Tập 16 - Trang 578-590 - 2019
Yousef Kazemzadeh, Behnam Dehdari, Zahra Etemadan, Masoud Riazi, Mohammad Sharifi
Nanofluids because of their surface characteristics improve the oil production from reservoirs by enabling different enhanced recovery mechanisms such as wettability alteration, interfacial tension (IFT) reduction, oil viscosity reduction, formation and stabilization of colloidal systems and the decrease in the asphaltene precipitation. To the best of the authors’ knowledge, the synthesis of a new...... hiện toàn bộ
Drained rock volume around hydraulic fractures in porous media: planar fractures versus fractal networksElsevier BV - Tập 16 - Trang 1064-1085 - 2019
Kiran Nandlal, Ruud Weijermars
This study applies the Lindenmayer system based on fractal theory to generate synthetic fracture networks in hydraulically fractured wells. The applied flow model is based on complex analysis methods, which can quantify the flow near the fractures, and being gridless, is computationally faster than traditional discrete volume simulations. The representation of hydraulic fractures as fractals is a ...... hiện toàn bộ
SRXRF experiments and analytical methods of mineral individual fluid inclusionsElsevier BV - Tập 4 - Trang 63-67 - 2008
Chunxue Wu, Yuying Huang, Hongkui Li, Chuanren Chen, Wei He, Kuifa Li
This paper focuses on the micro-beam and trace element non-destructive experiment and analytical method of mineral fluid inclusions by synchrotron radiation X-ray fluorescence (SRXRF) microprobe at Beijing Synchrotron Radiation Facility (BSRF). The experimental instrument, measurement process and calculating method are introduced. A set of oil-and gas-containing typical mineral fluid inclusions ta...... hiện toàn bộ
Evaluation of numerical schemes for capturing shock waves in modeling proppant transport in fracturesElsevier BV - Tập 14 - Trang 731-745 - 2017
Morteza Roostaei, Alireza Nouri, Vahidoddin Fattahpour, Dave Chan
In petroleum engineering, the transport phenomenon of proppants in a fracture caused by hydraulic fracturing is captured by hyperbolic partial differential equations (PDEs). The solution of this kind of PDEs may encounter smooth transitions, or there can be large gradients of the field variables. The numerical challenge posed in a shock situation is that high-order finite difference schemes lead t...... hiện toàn bộ
