## Abstract

Methods and compositions for gravel packing a wellbore penetrating a subterranean formation are described. The methods include providing a gravel packing fluid and contacting the subterranean formation with the gravel packing fluid so as to place a gravel pack in or near a portion of the subterranean formation. The gravel packing fluid includes a particulate agent and hydroxypropyl starch phosphate.

## Claims

### Claim 1

A method of gravel packing a wellbore penetrating a subterranean formation comprising:
providing a gravel packing fluid comprising a particulate agent and hydroxypropyl starch phosphate, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.1 to 10 weight percent of the gravel packing fluid; and
contacting the subterranean formation with the gravel packing fluid so as to place a gravel pack in or near a portion of the subterranean formation.

### Claim 2 (depends on 1)

The method of claim 1, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.5 to 6 weight percent of the gravel packing fluid.

### Claim 3 (depends on 2)

The method of claim 2, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.8 to 5 weight percent of the gravel packing fluid.

### Claim 4 (depends on 1)

The method of claim 1, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 4 weight percent of the gravel packing fluid.

### Claim 5 (depends on 1)

The method of claim 1, wherein the gravel packing fluid further comprises an aqueous carrier fluid.

### Claim 6 (depends on 5)

The method of claim 5, wherein the aqueous carrier fluid comprises a bromide-based or a chloride-based aqueous brine carrier liquid.

### Claim 7 (depends on 1)

The method of claim 1, further comprising reducing a viscosity of the gravel packing fluid.

### Claim 8 (depends on 7)

The method of claim 7, wherein the gravel packing fluid further comprises a breaker, and the gravel packing fluid is exposed to bottomhole temperatures of about 250° F. or less.

### Claim 9 (depends on 7)

The method of claim 7, wherein reducing the viscosity of the gravel packing fluid comprises exposing the gravel packing fluid to bottomhole temperatures of from about 300° F. to about 305° F.

### Claim 10 (depends on 9)

The method of claim 9, wherein the gravel packing fluid further comprises a gel stabilizer.

### Claim 11 (depends on 1)

The method of claim 1, wherein the wellbore comprises a deviated wellbore.

### Claim 12 (depends on 1)

The method of claim 1, wherein the particulate agent comprises sand.

### Claim 13

A method of gravel packing a deviated wellbore penetrating a subterranean formation comprising:
providing a gravel packing fluid that comprises hydroxypropyl starch phosphate, a particulate agent, and an aqueous carrier fluid, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.1 to 10 weight percent of the gravel packing fluid;
introducing the gravel packing fluid into the subterranean formation through the deviated wellbore; and
depositing the particulate agent within the deviated wellbore to form a permeable pack.

### Claim 14 (depends on 13)

The method of claim 13, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 4 weight percent of the gravel packing fluid.

### Claim 15 (depends on 13)

The method of claim 13, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.5 to 6 weight percent of the gravel packing fluid.

### Claim 16 (depends on 13)

The method of claim 13, further comprising reducing a viscosity of the gravel packing fluid.

### Claim 17 (depends on 16)

The method of claim 16, wherein the gravel packing fluid further comprises a breaker, and the gravel packing fluid is exposed to bottomhole temperatures of about 250° F. or less.

### Claim 18 (depends on 16)

The method of claim 16, wherein the gravel packing fluid further comprises a gel stabilizer and reducing the viscosity of the gravel packing fluid comprises exposing the gravel packing fluid to bottomhole temperatures of from about 300° F. to about 305° F.

### Claim 19 (depends on 13)

The method of claim 13, wherein the aqueous carrier fluid comprises a bromide-based or a chloride-based aqueous brine carrier liquid.

### Claim 20 (depends on 13)

The method of claim 13, wherein the particulate agent comprises sand.
