Oil-based drilling fluids for high pressure and high temperature drilling operations

Oil-based drilling fluids for high pressure and high temperature drilling operations

Oil-based drilling fluid compositions comprising an oil phase comprising a base oil, an aqueous phase comprising water, at least one emulsifier, and one or more additives. The at least one emulsifier comprises an amino amide comprising the formula R-CO-NH-R′-NH2, where R is a fatty acid alkyl and R′...

Beschreibung
Zusammenfassung:Oil-based drilling fluid compositions comprising an oil phase comprising a base oil, an aqueous phase comprising water, at least one emulsifier, and one or more additives. The at least one emulsifier comprises an amino amide comprising the formula R-CO-NH-R′-NH2, where R is a fatty acid alkyl and R′ is an alkyl group. The one or more additives are chosen from a wetting agent, a rheology modifier, a fluid-loss control additive, and a weighting additive. Methods of making the oil-based drilling fluid compositions and methods of drilling a subterranean well utilizing the oil-based drilling fluid compositions are also provided.
