NANOSTRIVE is a nanometre-sized surfactant polymer in drilling fluids that provide excellent microfracture plugging ability, particularly in shale formations, which directly contributes to enhancing wellbore stability and fluid loss control. Penetration and Physical Plugging: NANOSTRIVE nanoparticles are able to penetrate into microfractures and pore spaces within the shale. Once inside these tiny spaces, the surfactants aggregate, effectively plugging the microfractures and preventing the loss of drilling fluid into the formation. This physical plugging helps maintain wellbore stability and minimizes fluid loss.
