  • dynamic viscosities of 2 pentanol with alkanes octane decane and dodecane at three temperatures t 293 15 298 15 and 303 15 k new unifac visco interaction parameters
    Journal of Chemical & Engineering Data, 2004
    Co-Authors: Begoña González, Jose Tojo, A Dominguez, Raquel Cores
    Abstract:

    In this work, the dynamic viscosities, densities, and speed of sound for the binary mixtures, 2-pentanol with several alkanes (octane, decane, and dodecane), at T = (293.15, 298.15, 303.15) K have been measured over the whole composition range and atmospheric pressure along with the properties of the pure components. Excess molar volumes, isentropic compresibility, deviations in isentropic Compressibility, and viscosity for the binary systems at the above-mentioned temperatures were calculated and fitted to Redlich−Kister equation to determine the fitting parameters and the root-mean-square deviations. The UNIQUAC equation was used to correlate the experimental data. Predictions of the dynamic viscosities of these binary mixtures from UNIFAC−VISCO and ASOG−VISCO methods have been made. The interaction parameters within secondary alcohols with alkanes (OHs/CH2, OHs/CH3) have been determined for their application in the predictive UNIFAC−VISCO method.

  • Relationship between the stress sensitivity and pore structure of shale
    Journal of Natural Gas Science and Engineering, 2018
    Co-Authors: Zhang Wentong, Wang Qing, Ning Zhengfu, Zhang Rui, Huang Liang, Cheng Zhilin
    Abstract:

    Abstract The pore structure of shale changes with variations in the effective stress, greatly affecting the gas production of shale. The relationship between pore structure and stress sensitivity has remained unclear to date. The porosity sensitivity exponent and pore Compressibility are two crucial parameters for describing the stress sensitivity and relate to the pore structure of shale. In this study, expressions of the porosity sensitivity exponent and pore Compressibility were deduced based on a dual-porosity model. The results show that the scale and quantity of the micro-fractures and matrix pores play an important role in determining the porosity sensitivity exponent and pore Compressibility. Regarding the pore structure of shale, a low ratio of the porosity of the matrix pores to the porosity of the micro-fractures causes the porosity sensitivity exponent to be low and the pore Compressibility to be high; consequently, the shale shows strong stress sensitivity. The results regarding the porosity sensitivity exponent and pore Compressibility indicate that the pore Compressibility is the dominant factor influencing the stress sensitivity. The pore Compressibility is affected by not only the pore structure of shale but also the mechanical properties of shale. Young's modulus is negatively correlated with pore Compressibility, while Poisson's ratio shows a positive relationship and can be neglected. The effect of tortuosity on the stress sensitivity was also studied. The fitting results for the Walsh model illustrate that the tortuosity increases the degree of stress sensitivity. The results of this study identified the relationship between stress sensitivity and pore structure of shale, which will enable reservoir engineers to accurately predict stress sensitivity and investigate the permeability and porosity of shale based on its pore structure.
