  • Method of generating heat and vibration in a subterranean hydrocarbon-bearing formation
    Patent number: 6681857
    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 PEH-3CO, thereby generating heat, shock, and CO2. A preferred method comprises the steps of depositing PEH-3CO into the formation and depositing an acid into the formation to cause the PEH-3CO to decompose and generate heat and gas.
