Abstract
A swellable downhole article includes a swellable material and a carbon nitride material. The swellable material may include at least one of an elastomeric material and an absorbent material. The carbon nitride material may remove cations from a downhole fluid. Methods of forming the swellable downhole article are also disclosed, as are methods of forming a carbon nitride containing material for removing contaminants from a fluid.
Claims20
A swellable downhole article, comprising:
- a swellable material having a shape defining an inner diameter configured for receiving a portion of an outer diameter of a portion of a tubular component, the swellable material comprising at least one of an elastomeric material or an absorbent material;
- and
- a carbon nitride material comprising a C3N4 polymer material configured for removing cations from a wellbore fluid.
A method of forming a swellable downhole article, the method comprising:
- forming a swellable material comprising at least one of an elastomeric material or an absorbent material, the swellable material formulated and configured to expand from an initial state to a swollen state upon contacting a wellbore fluid;
- and
- providing a carbon nitride material comprising a C3N4 polymer material wherein the carbon nitride material is at least one of dispersed in the swellable material or disposed in a material proximate the swellable material.
