By reducing friction between the drill string and the formation or casing, lubricants and rate of penetration (ROP) enhancers minimize torque and drag., Lubricants are added to drilling fluids to... read more →
Shale inhibitors minimize water’s ability to hydrate clay, gumbo and reactive shales. Hydration causes swelling, wellbore instability, high torque and drag, and stuck pipe. (Delay or prevent shale swelling and... read more →
Drilling fluids must be able to form a solid filter cake on the wellbore wall which prevents the flow of fluid into the formation. By promoting the formation of a... read more →
