    摘要: A non-toxic, inexpensive synthetic fluid for use in wellbore fluids (e.g., drilling fluids) is selected from the group consisting of (A) fluids having (I) a pour point greater than about -30.degree. C. (-22.degree. F.) and (II) a cetane index greater than 50, and comprising (i) at least about 95 weight percent hydrocarbons containing 11 or more carbon atoms, (ii) greater than 5 weight percent hydrocarbons containing 18 or more carbon atoms, (iii) at least about 50 weight percent isoparaffins, (iv) at least about 90 weight percent total paraffins, (v) about 1 or less weight percent naphthenics, (vi) less than 0.1 volume percent aromatics, and (vii) at least 2 hydrocarbons containing a consecutive number of carbon atoms, and (B) fluids comprising (i) at least about 95 weight percent hydrocarbons containing 10 or more carbon atoms and (ii) at least about 90 weight percent n-paraffins.

    摘要: A method for controlling fouling of a flashing vessel or heat-exchange surface exposed to a high-enthalpy geothermal brine tending to form silicon-containing scale. The method adds a silicon-complexing amount of fluoroborate species to the brine to form a fluid mixture that does not produce substantial amounts of the scale when the temperature of the fluid mixture is reduced. The addition does not significantly increase corrosion rates of mild steel heat-exchanger materials of construction.

    摘要: A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture contains inorganic cement particles, a liquid styrene mixture and one or more poly-olefinically unsaturated co-monomers in a greater amount than the styrene. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferably selected from a group including trimethylolpropane-trimethacrylate, trimethylolpropane-methacrylate, divinyl benzene, and hexadiene. Mixing liquid and solid aggregate components forms a slurry which is transferred to a pipe interior and centrifugally cast to form the liner. The composition avoids the need for high temperature curing the toxic reactive unsaturates to co-polymerize and cross-link polystyrene. A preferred embodiment incorporates the use of relatively high concentrations of cement material, usually above about 40 weight percent of the aggregate component of the mixed slurry, to further improve chemical resistance and strength characteristics.
