Dual telemetric coiled tubing system
A dual telemetric coiled tubing running string for disposing a bottom hole assembly into a wellbore. The dual telemetric coiled tubing running string includes a string of coiled tubing which defines a flowbore along its length, an electrical wire conduit disposed within the flowbore, and an optic fiber disposed within the flowbore.
1. A dual telemetric coiled tubing running string for disposing a bottom hole assembly which is at least one of the group consisting of: a fishing bottom hole assembly, an acidizing/fracturing bottom hole assembly, a cleanout bottom hole assembly or an electrically powered tool into a wellbore, the dual telemetric coiled tubing running string comprising:
a string of coiled tubing which defines a flowbore along its length;
an electrical wire conduit disposed within the flowbore; and
an optic fiber disposed within the flowbore and terminating above the bottom hole assembly, the optic fiber not being connected to a sensor at point of termination.
2. The dual telemetric coiled tubing running string of claim 1 wherein the electrical wire conduit is encased within a protective tube within the flowbore.
3. The dual telemetric coiled tubing running string of claim 1 wherein the optic fiber is encased within a protective tube within the flowbore.
4. The dual telemetric coiled tubing running string of claim 3 wherein the optic fiber is operably associated with an optical time-domain reflectometer to receive optical telemetry from the optic fiber which is representative of a detected second operating parameter within the flowbore.
5. The dual telemetric coiled tubing running string of claim 4 wherein the second operating parameter is a parameter from the group consisting of: temperature and acoustic.
6. The dual telemetric coiled tubing running string of claim 1 wherein the electrical wire conduit is operably associated with a sensor within the wellbore and transmits a signal representative of a first operating parameter sensed by the sensor.
7. The dual telemetric coiled tubing running string of claim 6 wherein the first operating parameter is a parameter from the group consisting of: temperature, pressure, depth and gamma.
8. The dual telemetric coiled tubing running string of claim 1 wherein the electrical wire conduit and the optic fiber are each individually encased within a separate protective tube.
9. A work string to be disposed within a wellbore, the work string comprising:
a bottom hole assembly which is at least one of the group consisting of: a fishing bottom hole assembly, an acidizing/fracturing bottom hole assembly, a cleanout bottom hole assembly or an electrically powered tool;
a dual telemetric coiled tubing running string for disposing a bottom hole assembly into a wellbore, the dual telemetric coiled tubing running string having:
a string of coiled tubing which defines a flowbore along its length;
an electrical wire conduit disposed within the flowbore; and
an optic fiber disposed within the flowbore and terminating above the bottom hole assembly, the optic fiber not being connected to a sensor at point of termination.
10. The work string of claim 9 wherein the electrical wire conduit is encased within a protective tube within the flowbore.
11. The work string of claim 9 wherein the optic fiber is encased within a protective tube within the flowbore.
12. The work string of claim 9 wherein the electrical wire conduit is operably associated with a sensor within the wellbore and transmits a signal representative of a first operating parameter sensed by the sensor.
13. The work string of claim 12 wherein the first operating parameter is a parameter from the group consisting of: temperature, pressure, depth and gamma.
14. The work string of claim 9 wherein the optic fiber is operably associated with an optical time-domain reflectometer to receive optical telemetry from the optic fiber which is representative of a detected second operating parameter within the flowbore.
15. The work string of claim 14 wherein the second operating parameter is a parameter from the group consisting of: temperature and acoustic.
16. The work string of claim 9 wherein the electrical wire conduit and the optic fiber are each individually encased within a separate protective tube.
