Abstract

A method of treating a formation includes, setting a treating plug within a structure, withdrawing a mandrel from the treating plug after having set the treating plug, maintaining the setting of the treating plug within the structure without a member extending longitudinally through the treating plug, pumping fluid against a plug seated at the treating plug, treating a formation upstream of the treating plug, and disintegrating at least a portion of the treating plug.

Claims (33)

1. A method of treating a formation, comprising:

guiding a cone supported by a mandrel into a treating plug positioned within a structure;

setting the treating plug with the cone;

withdrawing the mandrel from the treating plug after having set the treating plug;

maintaining the setting of the treating plug within the structure with the cone without a member extending longitudinally through the treating plug;

pumping fluid against a plug seated upon the cone;

treating a formation upstream of the treating plug; and

disintegrating at least a portion of the treating plug.

2. The method of treating the formation of claim 1 , further comprising positioning the treating plug within the structure.

3. The method of treating the formation of claim 1 , further comprising compressing the treating plug longitudinally.

4. The method of treating the formation of claim 3 , further comprising supporting the longitudinally compressive loads applied to the treating plug with the mandrel extending longitudinally through the treating plug.

5. The method of treating the formation of claim 1 , further comprising running the plug within the structure to the treating plug.

6. The method of treating the formation of claim 1 , further comprising stimulating the earth formation.

7. The method of treating the formation of claim 1 , further comprising fracturing the earth formation.

8. The method of treating the formation of claim 1 , further comprising unanchoring the treating plug from the structure.

9. The method of treating the formation of claim 1 , further comprising sealing the treating plug to the structure.

10. The method of treating the formation of claim 1 , further comprising disintegrating slips of the treating plug.

11. The method of treating the formation of claim 1 , further comprising disintegrating the cone of the treating plug.

12. The method of treating the formation of claim 1 , further comprising disintegrating a seal of the treating plug.

13. The method of treating the formation of claim 1 , further comprising disintegrating the entire treating plug.

14. A method of temporarily isolating a first section of a wellbore from a second section of the wellbore, comprising:

guiding a cone supported by a mandrel into a settable plug;

setting, with the cone, the settable plug within the wellbore;

withdrawing the mandrel from the settable plug after having set the settable plug;

maintaining the setting of the settable plug within the wellbore with the cone without a member extending longitudinally through the settable plug;

pumping fluid against a plug seated upon the cone; and

disintegrating at least a portion of the settable plug.

15. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 14 , further comprising cementing a structure within the wellbore.

16. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 14 , further comprising supporting longitudinally compressive loads applied to the settable plug during setting thereof with the mandrel extending longitudinally through the settable plug.

17. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 14 , further comprising treating an earth formation in fluidic communication with the first section of the wellbore.

18. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 17 , wherein treating includes hydraulic fracturing, a stimulation, tracer injection, cleaning, acidizing, steam injection, water flooding, cementing, and combinations of two or more of the foregoing.

19. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 14 , further comprising disintegrating the entire settable plug.

20. The method of temporarily isolating the first section of the wellbore from the second section of the wellbore of claim 14 , further comprising unanchoring the settable plug.
