Abstract
Official abstract text for this publication.
According to one aspect of the inventions, emulsion compositions are provided. Emulsions according to this aspect include: (a) a water-insoluble resinous material; (b) water; and (c) an emulsifier, wherein the emulsifier comprises a non-ionic, a cationic, or a zwitterionic emulsifier; wherein the continuous phase of the emulsion comprises the water; wherein a dispersed phase of the emulsion comprises the resinous material; wherein the dispersed phase is in the form of droplets having a size distribution range such that at least 50% of the droplets have a size of 0.5 micrometers-500 micrometers; wherein the resinous material of the droplets is in a concentration of at least 5% by weight of the water; and wherein the composition of the droplets has a viscosity of less than 2,000 Poise measured at 20° F. According to another aspect of the inventions, methods are provided for treating a portion of a subterranean formation. Methods according to this aspect include the steps of: (a) forming an emulsion according to the composition described above; and (b) introducing the emulsion into a portion of a subterranean formation.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising the steps of: (a) forming an emulsion, the emulsion comprising: (i) a water-insoluble resinous material; (ii) water; (iii) an emulsifier, wherein the emulsifier comprises a cationic emulsifier; and (iv) a suspending agent, wherein the suspending agent, when tested at a concentration of 0.5% by weight in water, provides a fluid having an elastic modulus of greater than 1 Pa as measured within the linear viscoelastic region; wherei…
