Abstract
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 CO . 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.
