Several methods and devices are provided herein to generate shock waves that are used in the oil industry for well drilling, hydrocarbon or gas exploitation, fracking process or improved oil recovery (IOR), enhanced oil recovery (EOR), cleaning of process waters, oil spills byproducts and oil pipes,
Several methods and devices are provided herein to generate shock waves that are used in the oil industry for well drilling, hydrocarbon or gas exploitation, fracking process or improved oil recovery (IOR), enhanced oil recovery (EOR), cleaning of process waters, oil spills byproducts and oil pipes, which can be used as independent systems or as auxiliary systems concomitantly with other existing technologies. The different devices consist of generating shock waves utilizing either one or more laser sources, or a self-generated combustible gas supply, or a micro-explosive pellet, or piezocrystals, or a piezofiber composite structure.

1. A method for hydraulic fracturing of rock formations using shock waves for oil recovery comprising: inserting at least one shock wave device comprising at least one shock wave generator including at least one laser emitter into an oil production well bore casing, wherein the well bore casing penetrates a subterranean rock formation comprising at least rock and oil;generating a shock wave with the at least one laser emitter of the at least one shock wave generator through creation of a plasma bubble adjacent to a reflector of the at least one shock wave device;controlling laser energy of the at least one laser emitter to control size of the plasma bubble and magnitude of a generated shock wave; andfocusing the generated shock wave with the reflector into a target location of the subterranean rock formation. 2. The method of claim 1, further comprising monitoring performance of the at least one shock wave device by measuring the reaction temperature of collapse of the plasma bubble with an optical fiber assembly positioned adjacent the laser emitter. 3. The method of claim 2, further comprising locating a perforation in the well bore casing and aligning the reflector with the perforation and focusing the generated shock wave through the perforation to the target location. 4. The method of claim 3, further comprising aligning the reflector to the perforation using at least one of a proximity sensor and digital optic that detects at least one of metal and an opening of the well bore casing. 5. The method of claim 4, wherein two or more proximity sensors or digital optics are located on the perimeter of the reflector. 6. The method of claim 5, further comprising moving the reflector into alignment with the perforation with an electromechanical drive. 7. The method of claim 6, wherein the reflector is ellipsoidal. 8. The method of claim 1, wherein the reflector is ellipsoidal. 9. The method of claim 2, wherein the reflector is ellipsoidal. 10. The method of claim 3, wherein the reflector is ellipsoidal. 11. The method of claim 4, wherein the reflector is ellipsoidal. 12. The method of claim 5, wherein the reflector is ellipsoidal. 13. The method of claim 1, further comprising locating a perforation in the well bore casing and aligning the reflector with the perforation and focusing the generated shock wave through the perforation to the target location. 14. The method of claim 13, further comprising aligning the reflector to the perforation using at least one of a proximity sensor and digital optic that detects at least one of metal and an opening of the well bore casing. 15. The method of claim 14, wherein two or more proximity sensors or digital optics are located on the perimeter of the reflector. 16. The method of claim 13, wherein the reflector is ellipsoidal. 17. The method of claim 13, further comprising moving the reflector into alignment with the perforation with an electromechanical drive. 18. The method of claim 14, further comprising moving the reflector into alignment with the perforation with an electromechanical drive. 19. The method claim 3, wherein said aligning includes providing rotational and longitudinal movement to the reflector. 20. The method claim 13, wherein said aligning includes providing rotational and longitudinal movement to the reflector.
