## Abstract

Systems and methods for treating subterranean formations using deagglomerated inorganic clay particles are provided. In one embodiment, the methods comprise: providing a treatment fluid that comprises a base fluid, a consolidating agent, and a deagglomerated inorganic clay particle; introducing the treatment fluid into at least a portion of a subterranean formation so as to contact unconsolidated particles within the subterranean formation with the treatment fluid; and allowing the consolidating agent and the deagglomerated inorganic clay particle to consolidate at least a portion of the unconsolidated particulates in the portion of the subterranean formation.

## Claims

### Claim 1

A method comprising:
providing a treatment fluid that comprises a base fluid, a consolidating agent, and a plurality of deagglomerated inorganic clay nanotubes, wherein at least 50% of the deagglomerated inorganic clay nanotubes are individual nanotubes;
introducing the treatment fluid into at least a portion of a subterranean formation so as to contact unconsolidated particulates in the subterranean formation with the treatment fluid; and
allowing the consolidating agent and the deagglomerated inorganic clay nanotubes to consolidate at least a portion of the unconsolidated particulates in the portion of the subterranean formation.

### Claim 2 (depends on 1)

The method of claim 1, wherein the deagglomerated inorganic clay nanotubes comprise at least one material selected from the group consisting of: halloysite, hectorite, aluminum silicate, and any combination thereof.

### Claim 3 (depends on 1)

The method of claim 1, wherein at least a portion of the deagglomerated inorganic clay nanotubes have a length of from about 1 pm to about 1000 nm.

### Claim 4 (depends on 1)

The method of claim 1, wherein the consolidating agent comprises at least one agent selected from the group consisting of: a resin, a silane coupling agent, and any combination thereof.

### Claim 5 (depends on 1)

The method of claim 1, further comprising allowing the consolidating agent to form a coating on the unconsolidated particulates.

### Claim 6 (depends on 1)

The method of claim 1, wherein the treatment fluid further comprises a foamer.

### Claim 7 (depends on 1)

The method of claim 1, wherein at least a portion of the deagglomerated inorganic clay nanotubes have a length of from about 0.2 nm to about 1 nm.

### Claim 8

A method comprising:
providing a consolidating agent, a plurality of proppant particulates, and deagglomerated inorganic clay nanotubes, wherein at least 50% of the deagglomerated inorganic clay nanotubes are individual nanotubes;
introducing the consolidating agent, the plurality of proppant particulates, and the deagglomerated inorganic clay nanotubes into at least a portion of a subterranean formation;
allowing the consolidating agent to at least partially coat the proppant particulates, thereby creating coated proppant particulates; and
placing the coated proppant particulates and the deagglomerated inorganic clay nanotubes in at least a portion of the subterranean formation so as to form a proppant pack.

### Claim 9 (depends on 8)

The method of claim 8, wherein at least a portion of the deagglomerated inorganic clay nanotubes have a length of from about 1 pm to about 1000 nm.

### Claim 10 (depends on 8)

The method of claim 8, wherein the deagglomerated inorganic clay nanotubes comprise at least one material selected from the group consisting of: halloysite, hectorite, aluminum silicate, and any combination thereof.

### Claim 11 (depends on 8)

The method of claim 8, wherein the consolidating agent comprises at least one agent selected from the group consisting of: a resin, a silane coupling agent, and any combination thereof.

### Claim 12 (depends on 8)

The method of claim 8 wherein the consolidating agent, the plurality of proppant particulates, and the deagglomerated inorganic clay nanotubes are provided in a treatment fluid that is introduced into the portion of the subterranean formation using one or more pumps.

### Claim 13 (depends on 8)

The method of claim 8, wherein at least a portion of the deagglomerated inorganic clay nanotubes have a length of from about 0.2 nm to about 1 nm.
