Abstract
A method of servicing a wellbore in a subterranean formation comprising placing a wellbore servicing fluid comprising a lost-circulation composite material into a wellbore, wherein the lost-circulation composite material comprises a swellable component and a reinforcing component. A wellbore servicing fluid comprising a reinforcing component disposed within a swellable component wherein the swellable component comprises a crosslinked polymer.
Claims18
A wellbore servicing fluid comprising:
- a lost-circulation composite material comprising a reinforcing component disposed within a water-swellable component, wherein the water-swellable component comprises a superabsorber,
- wherein the superabsorber is selected from the group consisting of crosslinked hydrolyzed polyacrylonitrile;
- hydroxyethyl cellulose;
- crosslinked polymers of two or more of allylsulfonates;
- 2-acrylamido-2-methyl-1-propanesulfonic acid;
- 3-allyloxy-2-hydroxy-1-propane-sulfonic acid;
- and combinations thereof;
- wherein the reinforcing component is selected from the group consisting of cotton, wool, silk, hemp, linen, jute, sisal, and combinations thereof;
- and
- wherein the superabsorber, the reinforcing component, or both, are corona treated, plasma treated, photochemically treated, or any combination thereof, to promote formation of the lost-circulation composite material.

A method of servicing a wellbore in a subterranean formation comprising:
- providing a reinforcing component and a swellable component comprising a superabsorber,
- wherein the superabsorber is selected from the group consisting of crosslinked hydrolyzed polyacrylonitrile;
- hydroxyethyl cellulose;
- crosslinked polymers of two or more of allylsulfonates;
- 2-acrylamido-2-methyl-1-propanesulfonic acid;
- 3-allyloxy-2-hydroxy-1-propane-sulfonic acid;
- and combinations thereof, and
- wherein the reinforcing component is selected from the group consisting of cotton, wool, silk, hemp, linen, jute, sisal, and combinations thereof;
- subjecting the superabsorber, the reinforcing component, or both, to corona treatment, plasma treatment, photochemical treatment, or combinations thereof;
- swelling the superabsorber in the presence of water and the reinforcing component to form a lost-circulation composite material;
- dehydrating the lost-circulation composite material;
- adding the dehydrated lost-circulation composite material to a wellbore servicing fluid;
- and
- placing the wellbore servicing fluid into the wellbore.
