La presente invención se dirige a un fluido de pozoy en particular, a un fluido de perforación que tiene bajascantidades de nanoparticulas que actúan como un material depérdida de fluido para reducir la pérdida de fluido en unaformación subterránea. El fluido es un fluido de pozo quecontiene nanoparticulas que comprende un fluido base yaproximadamente 5% por peso o menos de nanoparticulas, paraprevenir o reducir la pérdida de fluido hacia una formaciónsubterránea, en donde el fluido de pozo es un fluido deperforación, un fluido pesado, un fluido de terminación, o unfluido de pre-estimulación. La invención incluye tambiénmétodos para la formación in situ y ex situ de lasnanoparticulas.The present invention is directed to a well fluid and in particular, to a drilling fluid having low amounts of nanoparticles that act as a fluid loss material to reduce fluid loss in an underground formation. The fluid is a well fluid that contains nanoparticles comprising a base fluid and approximately 5% by weight or less of nanoparticles, to prevent or reduce the loss of fluid into an underground formation, where the well fluid is a drilling fluid, a heavy fluid, a termination fluid, or a pre-stimulation fluid. The invention also includes methods for the in situ and ex situ formation of nanoparticles.
