  • Publication number: 20030187079
    Abstract: A preferred emulsifier blend includes ethoxylated alcohols containing hydrocarbons of C10-C16 and preferably having on average at least 2.8 ethoxy and/or alcohol groups per chain and a glycerol mono- and/or di-oleates, preferably in a ratio of from 9:1 to 4:6. These emulsion blends are particularly useful when mixed with hydroisomerized oils and water, for subsequent application as a spray oil to agricultural crops. The emulsion blends of the present invention also find particular utility when mixed with conventional spray oils and hard water.

  • Publication number: 20020139962
    Abstract: A dielectric fluid comprises an isoparaffinic base oil and hydrogen donor compound. The base oil may be a hydroisomerized isoparaffinic oil, and the hydrogen donor may be a substituted, or partially saturated aromatic compound. The resulting dielectric fluid exhibits negative hydrogen gassing properties along with good oxidative stability and low temperature performance.

  • Patent number: 6410488
    Abstract: A fluid suitable for use as the continuous phase in a drilling fluid is disclosed. The fluid is prepared by the sequential hydrotreating, hydroisomerization and hydrogenation of a crude oil feedstock. The fluid has good low temperature properties, including pour point and accordingly is useable in cold environments. A method of producing the fluid is also disclosed. The fluid may also be used as an additive to a drilling fluid having a continuous aqueous phase wherein it may act as, for example, a rate of penetration enhancer or a spotting fluid. The fluid may also be used as an additive to known drilling fluids such as internal olefins.
