Thermodynamic modeling of binary CH 4 –CO 2 fluid inclusions

The Influence of Hydrogeology to Generation of Hydrogen Sulfide of Low-Rank Coal in the Southeast Margin of Junggar Basin, China

“…The solubility of H 2 S in water is usually affected by temperature, pressure, salinity, water chemistry, and mixed gases [18,19]. Duan et al [20,21] and others believe that the solubility of H 2 S is essentially a gas-liquid equilibrium problem, and the gas-liquid equilibrium problem can be calculated by the equilibrium of H 2 S in the chemical position μ v H 2 S of the gas phase and the chemical position μ l H 2 S of the liquid phase.…”

A new method of reconstituting the P–T conditions of fluid circulation in an accretionary prism (Shimanto, Japan) from microthermometry of methane-bearing aqueous inclusions

“…To our knowledge, at least two thermodynamic models (Dubessy et al, 1992;Mao et al, 2011) have been devised to characterize such fluid inclusions exhibiting gas hydrates. However, none of them can be applied to the present study: the model of Dubessy et al (1992) does not make use of homogenization temperatures and the model of Mao et al 2011does not allow for the presence of NaCl.…”

“…Its temperature can be measured by microthermometry, generally between 0 • C and 15 • C, and this data gives us one additional constraint to characterize aqueous inclusions in terms of bulk content and density. Two models to this end (Dubessy et al, 1992;Mao et al, 2011) already exist in the literature, but none can be applied to Shimanto paleo-accretionary complex : Dubessy et al (1992) does not take into account T h,aq , whereas Mao et al (2011) does not take into account the presence of dissolved salts. We have, therefore, built a new algorithm allowing the complete characterization of the properties of an aqueous CH 4 and NaCl-bearing aqueous inclusion (i.e.…”

Evaluation of the pressure–volume–temperature ( PVT ) data of water from experiments and molecular simulations since 1990

“…So far, many models, such as equations of state (EOS), Helmholtz free energy models and many others, have been developed for the thermodynamic modeling of water or water-bearing fluids (Akinfiev and Diamond, 2010;Bakker, 1999Bakker, , 2003Bakker, , 2009Bakker et al, 1996;Blencoe et al, 1999;Bodnar et al, 2013;Driesner, 2007;Duan et al, 2008;Dubessy et al, 2005;Gottschalk, 2007;Holland and Powell, 2011;Hu et al, 2007;Ji and Zhu, 2013;Mao et al, 2010Mao et al, , 2011Mao et al, , 2013Spycher and Pruess, 2005;Steele-MacInnis et al, 2013;Sun and Dubessy, 2012;Wei and Powell, 2006).…”
