METHODS OF ZONAL ISOLATION AND TREATMENT DIVERSION
First Claim
1. A method of treating a subterranean formation penetrated by a well bore, comprising:
- a. providing a treatment fluid comprising a blend including a first amount of particulates having a first average particle size between about 3 mm and 2 cm and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size;
b. introducing the treatment fluid into the well bore; and
,c. creating a plug with said treatment fluid,wherein the second amount of particulates comprises a proppant.

15. A method of treating a subterranean formation of a well bore, wherein the well bore comprises a casing and at least one hole on said casing, said hole having a diameter, the method comprising:
-
a. providing a treatment fluid comprising a blend including a first amount of particulates having a first average particle size between about 50 to 100% of said diameter and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size; b. introducing the treatment fluid into the hole; c. creating a plug with said treatment fluid in the vicinity of or in the hole; and d. removing the plug, wherein the second amount of particulates comprises a proppant. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of fracturing a subterranean formation of a well bore, wherein the well bore comprises a casing and at least one hole on said casing, said hole having a diameter, the method comprising:
-
a. providing a diverting fluid comprising a blend including a first amount of particulates having a first average particle size between about 50 to 100% of said diameter and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size; b. introducing the diverting fluid into the hole; c. creating a diverting plug with said diverting fluid in the vicinity of or in the hole; d. fracturing the subterranean formation by using said diverting plug; and e. removing the diverting plug, wherein the second amount of particulates comprises a proppant.
