Olefin isomers as lubricants, rate of penetration enhancers and spotting fluid additives for water-based drilling fluids

摘要

The present invention provides non-toxic, biodegradable olefin isomers which may be used as lubricants, rate of penetration enhancers. and/or spotting fluids for water-based drilling minds. When used as a spotting fluid additive, the olefin isomers preferably are supplemented with functional additives, namely emulsifiers, viscosifiers, surfactants, and/or brine. When used as lubricants and/or rate of penetration enhancers, the olefin isomers preferably are used alone or in combination with surfactants.
