Abstract

Provided is a method of treating a subterranean formation comprising: preparing a well servicing fluid comprised of a base fluid, a temporary compacted material wherein the temporary compacted material is a compacted organic acid; placing the well servicing fluid into a subterranean formation; and allowing the temporary compacted material to gradually dissolve.

Claims (21)

1. A method of treating a subterranean formation comprising:

preparing a well servicing fluid comprised of a base fluid, a temporary compacted material wherein the temporary compacted material is a compacted organic acid and wherein the temporary compacted organic acid is compacted from powder or flake form to a larger particle at a pressure of approximately 3,500 psi to approximately 50,000 psi to alter solubility rate; placing the well servicing fluid into a subterranean formation; and allowing the temporary compacted material to gradually dissolve by an increase in temperature

wherein the compacted organic acid is adipic acid.

2. A method of claim 1 where the temporary compacted material is placed in the subterranean formation to influence the flow path of a wellbore or formation fluid.

3. A method of claim 1 where the temporary compacted material is placed in the subterranean formation such that the formation permeability is temporally altered.

4. A method of claim 1 where the temporary compacted material is placed in the subterranean formation where the wellbore configuration is altered.

5. A method of claim 1 where the compacted material further comprises a solubility aide.

6. A method of claim 5 where the solubility aide is anhydrous sodium borate.

7. A method of claim 1 where the temporary compacted material is a particle in the size range of 100 microns to 25 mm.

8. A method of claim 1 where the shape of the temporary compacted material is a shape other than round.

9. A method of claim 8 where the shape of the temporary compacted material is a rod, a cylinder, a disk, a plate, a filament, or has a cross section that is a square, rectangle, oval, triangle, or a composite shape of a combination of shapes.

10. A method of claim 5 where the solubility aide is present in the compacted particle in a range of 0.01% to 70% by weight.

11. A method of claim 1 where the temporary compacted material acts as a diverting agent, a fluid loss agent, a loss circulation agent, a filter cake, a bridge, a plug or a seal.

12. A method of claim 1 where the gradually soluble temporary compacted material is removed after the flow of production or injection fluids is started.

13. A method of claim 1 where the base fluid is water, a brine, seawater, brackish water, an oil, an ester, a solvent or any fluid used as a servicing fluid base fluid.

14. A method of claim 1 where the gradually soluble temporary compacted material may take from about 1 hour to about 2 months to dissolve.

15. A method of claim 1 where the servicing fluid comprising a temporary compacted material further comprises an organic acid powder or flakes.

16. A method of claim 1 where the servicing fluid comprising a temporary compacted material further comprises particles that can seal on the temporary compacted material.

17. A method of treating a subterranean formation comprising: preparing a well servicing fluid comprised of a base fluid, a temporary compacted material wherein the temporary compacted material is a compacted organic acid and wherein the temporary compacted organic acid is compacted from powder or flake form to a larger particle at a pressure of approximately 3,500 psi to approximately 50,000 psi to alter solubility rate; placing the well servicing fluid into a subterranean formation; and allowing the temporary compacted material to gradually dissolve by an increase in temperature

wherein the compacted material further comprises a solubility aide, and wherein the solubility aide is anhydrous sodium borate.

18. The method of claim 17 , wherein the compacted organic acid is adipic acid.
