    摘要: A lubricating composition is provided comprising a polyol ester which is the reaction product of a neopolyol with linear or branched monocarboxylic acids and mixtures thereof having from 1 to about 25 carbon atoms and a natural or GTL oil of lubricating viscosity and mixtures thereof and wherein the weight ratio of the ester to oil will be sufficient to provide a composition having a viscosity less than the individual viscosities of the ester and oil.

    摘要: A method for recovering oil in a reservoir by generating chemical microexplosions in the reservoir. The invention treats the hydrocarbon-bearing reservoir by decomposing in situ at least one imidazolidone derivative, thereby generating heat, shock, and CO2. A preferred method comprises the steps of depositing an imidazolidone derivative into the formation and depositing an acid into the formation to cause the imidazolidone derivative to decompose and generate heat and gas.
