This invention relates to drilling fluids and processes for making drilling fluids, such as for use in environmentally sensitive areas. The environmentally friendly drilling fluid includes a first fluid component having between about 5 weight percent to about 95 weight percent of olefins with a chain length in a range of between about C12 and about C48. The first fluid component includes at least about 50 weight percent trisubstituted olefin functionality. The environmentally friendly drilling fluid includes a second fluid component.

In an aerosol spray composition suitable for coating automobile exteriors, where the aerosol composition is pressurized in a container with propellant and includes water and a polyvinyl alcohol composition, the improvement being that said polyvinyl alcohol composition includes: a) from 50 to 99 wt % of a partially hydrolyzing first polyvinyl alcohol resin having a degree of hydrolysis in the range of from about 80 to about 90 percent; and (b) from 1 to 50 wt % of a second polyvinyl alcohol resin having an elevated degree of hydrolysis.

A real-time method of determining paste solids includes: correlating the refractive index of a paste with solute concentration in a solvent using a plurality of paste solids concentrations, typically including at least two paste solids concentrations greater than about 5 percent; submersing a fiber optic refractometer sensor into a sample and allowing it to equilibrate for a period of from about 30 seconds to about 20 minutes prior to measuring refractive index of the sample; measuring the refractive index of the paste sample with the fiber optic refractometer sensor; and determining the concentration of solute in the sample using the correlation.
