Figure 16-21 shows the solubility of water in some hydrocarbon liquids as a function of temperature.12 The data are for saturation of the hydrocarbon with water at a given temperature under the equilibrium pressure of the existing water, hydrocarbon liquid, and hydrocarbon gas phases. The conditions correspond to the equilibrium line Q7C on Figure 17-2.

From the authors point of view, introduction of this elementary stage to mechanisms of saturated hydrocarbon gas-phase oxidation [26] makes clearer the mechanisms of such complex chemical processes, especially at olefin formation with the same number of carbon atoms as in the initial hydrocarbon.

The Bossier sands produce some water, with rates ranging from 1 to 5 bbl/day for the life of the well. It is believed that no mobile liquid water phase exists in the reservoir. The source of long-term water production is probably water vapour that is originally dissolved in the hydrocarbon gas phase at reservoir conditions but condenses at the surface. This observation seems to also be confirmed by the low salinity, ranging from 40 000 to 60 000 ppm NaCl, of the produced waters. These salinities are significantly lower than the in-situ connate waters which often have salinities exceeding 200 000 ppm (Newsham Rushing 2002).
