Claims
- 1. A method for detecting detonation of a tubing conveyed perforating (TCP) gun in a wellbore comprising the steps for:
(a) placing a sensor in a wellbore; (b) detonating a TCP charge; and (c) detecting detonation of the TCP charge.
- 2. The method of claim 1, wherein the sensor comprises a tracer module containing a fluorescent tracer dye.
- 3. The method of claim 2, wherein the step of detecting detonation of the TCP charge in further comprising sensing tracer dye released from the tracer module upon detonation of the TCP charge.
- 4. The method of claim 1 wherein the sensor comprises a fibre optic sleeve surrounding a TCP charge string in the wellbore.
- 5. The method of claim 4, wherein the step of detecting detonating of the TCP charge in further comprising sensing changes in the electrical properties of the fibre optic sleeve upon detonation of the TCP charge.
- 6. The method of claim 1 wherein the sensor comprises an acoustic sensor in the wellbore.
- 7. The method of claim 6 wherein the step of detecting detonation of the TCP charge further comprises acoustically sensing detonation of the TCP charge.
- 8. A method of determining the contribution from a injection well to a producing well comprising the steps for:
(a) placing at least one identifiable tracer dye in an injection well, the tracer dye identifier being associated with the injection well; and (b) detecting the presence of at the at least one identifiable tracer dye at the producing well, thereby determining the contribution from the injection well to the producing well.
- 9. An apparatus for detecting detonation of a tubing conveyed perforating (TCP) gun in a wellbore comprising:
a TCP charge and detonator deployed in the well bore; and a detonation sensitive device that reacts to the detonation of the TCP charge.
- 10. The apparatus of claim 9, wherein the detonation sensitive device comprises a fluorescent tracer dye module that releases the dye upon detonation of the TCP charge, the apparatus further comprising a fluorescent dye detector for sensing release of the fluorescent dye.
- 11. The apparatus of claim 9, wherein the detonation sensitive device comprises a fibre optic sleeve adjacent the TCP charge that changes electrical properties upon detonation of the TCP charge, the apparatus further comprising a sensor for detecting changes in the electrical properties of the fibre optic sleeve upon detonation of the TCP charge.
- 12. The apparatus of claim 9, wherein the detonation sensitive device comprises an acoustic sensor that acoustically senses detonation of the TCP charge.
- 13. A apparatus for determining the contribution from a injection well to a producing well comprising:
(a) an injector for injecting an identifiable tracer dye into an injection well, the tracer dye identifier being associated with the injection well; and (b) detecting the presence of at the identifiable tracer dye at the producing well, thereby determining the contribution from the injection well to the producing well.
