Abstract
A method of clay swelling inhibition includes contacting an aqueous drilling fluid with a subterranean geological formation. The aqueous drilling fluid includes an acrylic acid functionalized cellulose diacrylate carbon nanocomposite (AA-Cellulose-NC) material in an amount of 0.1 to 2 percent by weight (wt. %) of the aqueous drilling fluid. The AA-Cellulose-NC material is deposited on and binds to an inner surface of the subterranean geological formation to form a hydrophobic filter cake layer to reduce swelling of clay in the subterranean geological formation.
