Patent ID: 8469110

Claim:
A method to increase petroleum production from an oil well drilled into a petroleum reservoir having an oil layer and a water layer, wherein at least one selected from one or more injection wells and one or more production wells are drilled into the oil layer and one or more injection wells are drilled into the water layer, comprising: delivering an explosive composition capable of generating CO 2 gas and heat into at least one selected from the one or more injection wells and the one or more production wells drilled into the oil layer, the explosive composition comprising a fuel component, an oxidizer component, and a nitrogen containing organic compound, the fuel component is one or more of a carbon powder and a hydrocarbon-based compound; delivering an acid through one or more injection wells drilled into the aqueous layer to acidify the aqueous layer; sealing the petroleum reservoir in a manner to confine pressure build-up within the petroleum reservoir; and detonating the explosive composition.
