“…2). We compare the data of Semenyuk et al [30], whose data are not used for parameterization, with our model for the NaCl-H 2 Table 4. Figures 3, 4, and 5 show the viscosity deviations between the experimental results and model predictions for every binary alkali-chloride system.…”

“…One of the most important thermophysical properties is the viscosity as a function of temperature, pressure, and salt concentration. The viscosity has been widely used for fluid flow simulations [1][2][3] and engineering designs whenever electrolyte solutions must be stirred, pumped, or moved through pipelines and other equipment. In the study of a sedimentary basin, the viscosity is also important, because variations in viscosity of formation waters have a significant effect on the flow pattern, with consequences for various basin processes.…”

An accurate viscosity (dynamic viscosity) model is developed for aqueous alkali-chloride solutions of the binary systems, LiCl-H 2 O, NaCl-H 2 O, and KCl-H 2 O, from 273 K to 623 K, and from 1 bar to 1,000 bar and up to high ionic strength. The valid ionic strengths for the LiCl-H 2 O, NaCl-H 2 O, and KCl-H 2 O systems are 0 to 16.7 mol · kg −1 , 0 to 6mol · kg −1 , and 0 to 4.5 mol · kg −1 , respectively. Comparison of the model with about 4,150 experimental data points concludes that the average absolute viscosity deviation from experimental data in the above range is within or about 1 % for the LiCl-H 2 O, NaCl-H 2 O, and KCl-H 2 O mixtures, indicating the model is of experimental accuracy. With a simple mixing rule, this model can be extrapolated to predict the viscosity of ternary aqueous alkali-chloride solutions, making it useful in reservoir fluid flow simulation. A computer code is developed for this model and can be obtained from the author: (maoshide@cugb.edu.cn).

Abstract. The steady response of the interface between two fluids with different density in a porous medium is considered during extraction through a line sink. Supercritical withdrawal, or coning as it is often called, in which both fluids are being withdrawn, is investigated using a coupled integral equation formulation. It is shown that for each entry angle of the interface into the sink there is a range of supercritical solutions that depend on the flow rate, and that as the flow rate decreases the cone narrows. As the magnitude of the entry angle increases this range of flow-rate values decreases to a narrow range as the entry becomes vertical. Only one branch of solutions (that with horizontal entry) has the property that the interface levels off at a finite height, and this is investigated as a separate branch of solution.

“…At a higher "supercritical rate", fluid from both layers will be removed. Yu [11] and Henderson et al [5] computed solutions of this type, and more recently Hocking and Zhang [6] found a range of such supercritical solutions using boundary element methods.…”

The steady response of the free surface of a fluid in a porous medium is considered during extraction of the fluid through a line sink. A conformal-mapping approach is used to derive exact solutions to a family of problems in which the line sink is placed at the apex of a wedge-shaped impermeable base, including the limiting cases of an unbounded aquifer and a flat-bottomed aquifer of finite depth. Both critical cusp solutions and sub-critical solutions are computed exactly as Fourier sine series.2000 Mathematics subject classification: primary 76S05.
