Abstract

Systems and methods of the present disclosure relate to identifying geometric features of a conduit. A method includes controlling a flow into or out of a conduit to induce pressure waves in the conduit; measuring, with a pressure transducer, pressure responses in the conduit due to contact of the pressure waves with a geometric feature of the conduit; and identifying the geometric feature, based on the pressure responses.

First claim

What is claimed is:

1. A method comprising:
controlling a flow into or out of a conduit to induce at least two positive pressure waves of at least two negative pressure waves in the conduit using a pump or pressure wave inducement source;
measuring, with a pressure transducer, pressure responses in the conduit due to contact of the at least two positive pressure waves or at least two negative pressure waves with a geometric feature of the conduit; and
identifying the geometric feature, based on differences in the pressure responses from the at least two positive pressure waves or at least two negative pressure waves.

2. The method of claim 1 , wherein measuring the pressure responses in the conduit includes measuring pressure responses induced by a reciprocating pump that removes fluid from the conduit to induce at least two negative pressure waves in the conduit.

3. The method of claim 1 , father comprising inducing at least two negative pressure waves in the conduit via a release of fluid from the conduit.

4. The method of claim 1 , further comprising inducing at least two positive pressure waves in the conduit via an addition of fluid into the conduit.

5. The method of claim 1 , wherein the geometric feature includes a bend.

6. The method of claim 5 , wherein the bend is a portion of a tee.

7. The method of claim 5 , wherein the bend is a portion of a wye.

8. The method of claim 5 , wherein the bend includes a curve.

9. The method of claim 1 , wherein identifying the geometric feature includes statistically analyzing the pressure responses to identify the geometric feature.

10. The method of claim 1 , wherein identifying the geometric feature includes analyzing, with machine learning, the pressure responses to identify the geometric feature.

11. A method comprising:
controlling a flow into or out of a conduit that includes a bend to induce pressure waves in the conduit;
measuring pressure responses in the conduit due to contact of the pressure waves with the bend; and
identifying a shape of the bend, based on the pressure responses.

12. The method of claim 11 , further comprising determining that the bend includes a tee.

13. The method of claim 11 , further comprising determining that the bend includes a tee.

14. The method of claim 11 , further comprising determining that the bend includes a wye.

15. The method of claim 11 , further comprising determining that the bend includes a curve.

16. The method of claim 11 , wherein identifying the geometric feature includes analyzing, with machine learning, the pressure responses to identify the shape of the bend.

17. The method of claim 11 , wherein identifying the geometric feature includes statistically analyzing the pressure responses to identify the shape of the bend.

18. The method of claim 11 , further comprising inducing at least two positive pressure waves in the conduit.

19. The method of claim 11 , further comprising inducing at least two negative pressure waves in the conduit.

20. The method of claim 11 , wherein measuring the pressure responses in the conduit includes measuring pressure responses induced by a pump or a valve.
