Abstract

A method for testing a loss control material, the method including filling a testing environment in a testing system with a first fluid, injecting a loss control material in a second fluid into the testing environment from a first end of the testing system, thereby displacing the first fluid across the testing environment to a second end of the testing system, and monitoring a formation of a barrier created by the loss control material.

First claim

What is claimed is:

1. A method comprising:
filling a testing environment in a testing system with a first fluid;
injecting a loss control material in a second fluid into the testing environment from a first end of the testing system, thereby displacing the first fluid across the testing environment to a second end of the testing system; and
monitoring a formation of a barrier created by the loss control material, the monitoring comprising:
collecting data from a plurality of pressure sensors; and
generating a pressure profile along a length of the testing environment using the collected data.

2. The method of claim 1 , wherein the plurality of pressure sensors are distributed at least between the first end and the second end of the testing system.

3. The method of claim 1 , wherein collecting data from the plurality of pressure sensors comprises measuring pressure at the first end of the testing system, the second end of the testing system, and at any point in between the first end and the second end of the testing system.

4. The method of claim 1 , further comprising injecting a third fluid into the testing environment.

5. The method of claim 4 , wherein injecting the third fluid into the testing environment is a stepped injection.

6. The method of claim 4 , further comprising circulating each of the first fluid, the second fluid, and the third fluid through the testing system.

7. The method of claim 6 , wherein circulating each of the first fluid, the second fluid, and the third fluid through the testing system comprises circulating each of the first fluid, the second fluid, and the third fluid through the testing system in a direction that is substantially orthogonal to a fluid flow path between the first end and the second of the testing system.

8. The method of claim 1 , further comprising applying a vacuum to the testing system.

9. The method of claim 1 , further comprising visually monitoring the loss control material in the second fluid while the loss control material in the second fluid is injected into the testing system.

10. The method of claim 1 , further comprising visually monitoring the third fluid while the third fluid is injected into the testing system.

11. The method of claim 1 , wherein the testing system simulates a formation.

12. A testing system comprising:
a first plate having an inlet, an outlet, and a plurality of openings formed through a surface of the first plate;
a second plate engaged with the first plate,
wherein the first plate and the second plate are configured such that a central cavity is formed between a portion of the first plate and the second plate; and
a plurality of pressure sensors engaged with the first plate through the plurality of openings formed in the first plate.

13. The system of claim 12 , further comprising an intermediate plate disposed between the first plate and the second plate, the intermediate plate having a central opening formed therethrough, the central opening forming the central cavity.

14. The system of claim 12 , the first plate having the central cavity formed therein.

15. The system of claim 12 , further comprising a pump coupled to the first plate, the pump configured to inject a fluid through the inlet of the first plate.

16. The system of claim 12 , wherein the first plate is engaged with the second plate by at least one engagement member.

17. The system of claim 12 , the first plate comprising a recessed portion formed around a plurality of engagement openings of the first plate.

18. The system of claim 17 , further comprising a sealing member disposed about the recessed portion of the first plate.

19. The system of claim 12 , further comprising a plurality of spherical testing units disposed within the central cavity.

20. The system of claim 12 , further comprising a circulation line coupled to the inlet of the first plate and a circulation outlet formed on the second plate.

21. The system of claim 20 , further comprising a circulation pump coupled to the circulation line.

22. The system of claim 12 , wherein the first plate is formed from a substantially transparent material.

23. A method comprising:
injecting a fluid into a testing environment of a testing system at a first end of the testing system, the fluid comprising a loss control material; and
visually monitoring a flow profile of the fluid along a length of the testing environment through an at least partially transparent first plate of the testing system.
