Abstract

In some examples a method of well treatment may comprise: providing a treatment fluid comprising a microemulsified resin additive, wherein the microemulsified resin additive comprises a continuous phase and a discontinuous phase, wherein the continuous phase comprises an aqueous liquid, wherein the discontinuous phase is in form of micelles of about 200 nm or less in diameter and comprises a resin; introducing the treatment fluid into a subterranean formation penetrated by a wellbore; and allowing the treatment fluid to set in the subterranean formation.

First claim

What is claimed is:

providing a treatment fluid comprising a microemulsified resin additive, wherein the microemulsified resin additive comprises a continuous phase and a discontinuous phase, wherein the continuous phase comprises an aqueous liquid, wherein the discontinuous phase is in the form of micelles comprising a resin, wherein at least 95% or more of the micelles are about 200 nm or less in diameter;
introducing the treatment fluid into a subterranean formation penetrated by a wellbore; and
allowing the treatment fluid to set in the subterranean formation.

2. The method of claim 1 , wherein the treatment fluid is foamed.

3. The method of claim 1 , wherein the micelles of the discontinuous phase are about 100 nanometers or less in diameter.

4. The method of claim 1 , wherein the resin is selected from the group consisting of epoxy resins, phenol-aldehyde resins, urea-aldehyde resins, urethane resins, phenolic resins, furan and furfuryl alcohol resins, phenolic and latex-modified phenolic resins, phenol formaldehyde resins, butoxymethyl butyl glycidyl ether resins, and polyester resins and any combination thereof.
