    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.

    摘要: A wide-cut lubricant base stock is made by hydroisomerizing and then catalytically dewaxing a waxy Fischer-Tropsch synthesized hydrocarbon fraction feed and comprises the entire dewaxate having an initial boiling point in the 650-75O° F.+ range. Formulated lubricating oils made by admixing the base stock with a commercial automotive additive package meet all specifications, including low temperature properties, for multigrade internal combustion engine crankcase oils. The waxy feed has an initial boiling point in the 650-750° F. range and continuously boils to an end point of at least 1050° F.+. Lower boiling hydrocarbons produced by the process are separated from the base stock by simple flash distillation. The base stock comprises the entire dewaxate having an initial boiling point in the 650-750° F. range.
