Abstract

A hydrocarbon recovery tubular system including one or more axially elongated tubulars arranged to receive a hydrocarbon bearing fluid therein. One or more helically curved conduits are positioned radially adjacent a surface of the one or more tubulars. One or more fibers are disposed in the one or more helically curved conduits and are immovably positioned at a shortest pathway through the one or more helically curved conduits.

Claims

1. A hydrocarbon recovery tubular system comprising:

one or more axially elongated tubulars arranged to receive a hydrocarbon bearing fluid therein;

one or more helically curved conduits positioned radially adjacent a surface of the one or more tubulars; and

one or more fibers disposed in the one or more helically curved conduits and immovably positioned at a shortest pathway through the one or more helically curved conduits.

2. The system of claim 1, wherein the one or more fibers are optical fibers.

3. The system of claim 1, wherein the surface is an outer surface of the one or more tubulars.

4. The system of claim 1, wherein the surface is an inner surface of the one or more tubulars.

5. The system of claim 1, wherein at least one of the one or more fibers is immovably positioned at an inside surface of the one or more conduits.

6. The system of claim 5, wherein the system further includes a hardenable material disposed in the one or more conduits to affix the at least one fiber to the inside surface.

7. The system of claim 6, wherein the hardenable material is a material containing epoxy.

8. The system of claim 6, wherein the hardenable material is thinned with a thinner.

9. The system of claim 8, wherein the thinner is acetone.

10. The system of claim 6, wherein the hardenable material is configured as a coating on the inside surface of the one or more conduits.

11. The system of claim 10, wherein the coating defines an open passageway that is receptive to a communication fluid.

12. The system of claim 10, wherein hardenable material is configured as a plurality of stacked coatings on the inside surface of the one or more conduits.

13. The system of claim 1, wherein the one or more fibers include one or more fiber bragg gratings therein.

14. The system of claim 1, wherein the one or more tubulars form at least a portion of a casing of the hydrocarbon recovery tubular system.
