Abstract
Drilling fluid compositions and methods for using drilling fluid compositions are provided with enhanced anti-bit balling properties that includes an aqueous base fluid, one or more drilling fluid additives, and an anti-bit balling additive where the anti-bit balling additive comprises a C15-C18 alkene or a mixture of two or more C15-C18 alkenes. Methods for using the drilling fluid compositions may further include mixing the mixing an aqueous base fluid with one or more drilling fluid additives and an anti-bit balling additive, wherein the anti-bit balling additive includes a C15-C18 alkene or a mixture of two or more C15-C18 alkenes, and introducing the drilling fluid to a subterranean formation.
