SWELLABLE DOWNHOLE STRUCTURES INCLUDING CARBON NITRIDE MATERIALS, AND METHODS OF FORMING AND USING SUCH STRUCTURES

摘要

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.

主权项

1. A method of forming a material for removing contaminants from a fluid, the method comprising:
providing a carbon nitride material having a structure comprising vacancies between triazine rings of the carbon nitride material; mixing the carbon nitride material with at least one of an elastomeric material, polyurethane, polyurea, polyamine, carbon black, graphite, carbon fiber, glass fiber, silica, a clay, calcium carbonate, bentonite, polytetrafluoroethylene, and molybdenum disulfide; and forming at least one of a filter or a membrane comprising the carbon nitride material, wherein the at least one of a filter or a membrane comprises between about fifteen percent by weight and about thirty-five percent by weight of the carbon nitride material.
