Abstract

Techniques of the present disclosure relate to proppant flowback control using a plug and perf completion. A method comprises disposing a resin in at least one cluster of fractures of a stage; disposing an activator for the resin in the stage; displacing the activator from the wellbore and into the at least one cluster of the stage with a plug attached to a perforating apparatus; setting the plug such that the resin and the activator are contained in the stage; and perforating a subsequent stage.

First claim

What is claimed is:

1. A method comprising:
disposing a resin in at least one cluster of fractures of a stage in a wellbore;
disposing an activator for the resin in the stage;
displacing the activator from the wellbore and into the at least one cluster of the stage with a plug attached to a perforating apparatus;
setting the plug such that the resin and the activator are contained in the stage; and
perforating a subsequent stage in the wellbore.

2. The method of claim 1 , further comprising:
disposing the resin in at least one cluster of fractures of the subsequent stage;
disposing the activator in the subsequent stage;
displacing the activator into the at least one cluster of the subsequent stage with a second plug attached to the perforating apparatus;
setting the second plug such that the resin and the activator are contained in the subsequent stage; and
perforating an additional stage in the wellbore.

3. The method of claim 1 , further comprising consolidating sand in the at least one cluster of the stage with the resin.

4. The method of claim 1 , further comprising consolidating sand in at least one cluster of fractures of a previously treated stage that comprises the resin, wherein the stage is between the previously treated stage and the subsequent stage.

5. The method of claim 1 , wherein the displacing the activator step comprises pumping the perforating apparatus and the plug downhole to displace the activator into the at least one cluster of the stage.

6. The method of claim 1 , wherein the disposing the activator step comprises pumping an acid or a hydrolysable ester into the stage.

7. The method of claim 1 , further comprising pumping a spacer in the wellbore between the disposing of the resin and the disposing of the activator into the stage.

8. The method of claim 1 , further comprising detaching the perforating apparatus from the plug after setting the plug.

9. The method of claim 1 , further comprising pumping a pre-flush into the stage before disposing the resin into the stage.

10. The method of claim 1 , wherein the resin and the activator are disposed into the stage simultaneously.

11. A method comprising:
(A) pumping a pre-flush into a stage of a wellbore;
(B) disposing a resin in at least one cluster of fractures of the stage;
(C) disposing an activator for the resin in the stage;
(D) displacing the activator into the at least one cluster of the stage with a plug attached to a perforating apparatus;
(E) setting the plug such that the resin and the activator are contained in the stage;
(F) consolidating sand for the stage; and
(G) perforating a subsequent stage of the wellbore.

12. The method of claim 11 , further comprising repeating steps (A)-(F) for the subsequent stage and repeating step (G) for an additional stage of the wellbore.

13. The method of claim 11 , further comprising consolidating sand in the at least one cluster of the stage with the resin.

14. The method of claim 11 , further comprising consolidating sand in at least one cluster of a previously treated stage that comprises the resin, wherein the stage is between the previously treated stage and the subsequent stage.

15. The method of claim 11 , wherein the displacing the activator step comprises pumping the perforating apparatus and the plug downhole to displace the activator into the at least one cluster of the stage.

16. The method of claim 11 , wherein the disposing the activator step comprises pumping an acid or an ester into the stage.

17. The method of claim 11 , further comprising pumping a spacer in the wellbore between the disposing of the resin and the disposing of the activator into the stage.

18. The method of claim 11 , further comprising detaching the perforating apparatus from the plug after setting the plug.

19. The method of claim 11 , further comprising moving the perforating apparatus up-hole from the stage after setting of the plug.

20. The method of claim 11 , wherein pumping the pre-flush comprises pumping a salt and a surfactant into the wellbore.
