Fluidos de perfuração à base de água. Parte I: Efeitos de aditivações poliméricas nas propriedades reológicas (Water based drilling fluids. Part I: Effects of polymeric additives in the rheological properties)

The effects of addition of four different polymeric additives in the rheological and water loss properties of clay dispersions as drilling fluids based on water were studied. The results show that these properties are strongly dependent on the polymeric additives as well as on polymer chain length.
