Oilfield nanocomposites
First Claim
1. An oilfield apparatus, comprising:
- an oilfield element made of a composite comprising;
a matrix material; and
a plurality of functionalized graphene sheets dispersed in the matrix material, wherein the oilfield apparatus is a downhole tool,wherein the plurality of functionalized graphene sheets comprise single-layer sheets and multi-layer sheets having a surface area per unit weight of at least 300 m2/g, andwherein the plurality of functionalized graphene sheets are functionalized with polymers with a polydispersity index such that the polymer hinders folding of the plurality of functionalized graphene sheets.

Abstract
An oilfield apparatus includes an oilfield element made of a composite that includes a matrix material; and a plurality of functionalized graphene sheets dispersed in the matrix material. A method of oilfield operation includes selecting an oilfield apparatus having an oilfield element, wherein at least a portion of the oilfield element is made of a composite comprising a plurality of functionalized graphene sheets dispersed in a matrix material; and using the oilfield apparatus in an oilfield operation, thereby exposing the oilfield element to an oilfield environment. A method for modifying a functionalized graphene sheet includes obtaining the functionalized graphene sheet; and subjecting the functionalized graphene sheet to atom transfer radical polymerization to attach polymers on surfaces of the functionalized graphene sheet. The polymers attached to the surfaces of the functional graphene sheet may comprise co-polymers or magnetic particles.
