ABSTRACT:
A method and apparatus are provided for improving the production of unswept and immovable oil from conventional oil wells. The oil recovery system utilizes an impulse wave device to produce impulse waves which travel down-hole and strike a bridge plug. When the impulse waves strike the bridge plug, weak elastic waves are created. After creation, the weak elastic waves propagate in all directions. The weak elastic waves are maintained in a general area near an oil formation by a conventional packer and a diffuser/deflector.
