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 (15)

1. A method of treating a subterranean formation consisting essentially of: placing a well servicing fluid comprising a base fluid and temporarily compacted benzoic acid into a subterranean formation wherein the temporarily compacted benzoic acid is compacted from powder or flake form to a larger particle at a pressure of approximately 500 psi to approximately 50,000 psi to alter solubility rate; and allowing the temporarily compacted benzoic acid to gradually dissolve solely by an increase in temperature.

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

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

5. A method of claim 1 , where the compacted benzoic acid further comprises a solubility aide.

6. A method of claim 5 where the solubility aid is present in the compacted benzoic acid in a range of 0.01% to 70% by weight.

7. A method of claim 1 where the temporary compacted benzoic acid 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 benzoic acid is a shape other than round.

9. A method of claim 8 where the shape of the temporary compacted benzoic acid is selected from one or more of 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 1 where the temporary compacted benzoic add acts as a diverting agent, a fluid loss agent, a loss circulation agent, a filter cake, a bridge, a plug or a seal.

11. A method of claim 1 where the temporary compacted benzoic acid of gradual solubility is removed after the flow of production or injection fluids is started.

12. 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.

13. A method of claim 1 where the gradual solubility of the temporary compacted benzoic acid may take from about 1 hour to about 2 months.

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

15. A method of claim 1 where the servicing fluid comprising a temporary compacted benzoic acid further comprises smaller particles that can seal on the temporary compacted benzoic acid.
