Self-Suspending Functionalized Proppant Particulates For Use In Subterranean Formation Operations

摘要

Functionalized proppant particulates including proppant particulates having functional groups chemically deposited thereon, the functional groups selected from the group consisting of an epoxy silane group, an amine silane group, an acrylyl silane group, and any combination thereof, and a swellable material chemically bound to one or more of the functional groups.

主权项

1. A method comprising:
providing functionalized proppant particulates,
wherein the functionalized proppant particulates comprise proppant particulates having functional groups chemically deposited thereon, the functional groups selected from the group consisting of an epoxy silane group, an amine silane group, an acrylyl silane group, and any combination thereof, and a swellable material chemically bound to one or more of the functional groups,wherein the swellable material has an unswelled volume; preparing a treatment fluid comprising an aqueous base fluid and the functionalized proppant particulates,
wherein the swellable material of the functionalized proppant particulates adopts an increased swelled volume in the aqueous base fluid, thereby suspending the functionalized proppant particulates therein; and introducing the treatment fluid into a subterranean.
