Abstract. Oil well cement slurries commonly incorporate several admixtures such as e.g. retarder, dispersant, fluid loss additive, anti-free water agent, deer etc. Between them, additive-additive interactions may occur which can result in incompatibilities and reduced performances (the most frequent case) or, oppositely, in improved effectiveness. Here, an …

ABSTRACT. With respect to the fluid loss behaviour of a cement slurry basically two stages need be considered: (i) a dynamic one corresponding to the placement and then (ii) a static one, the waiting on cement. During the first period the slurry flow is eroding the filter cake as it is growing, thus rapidly a steady state is reached where the filtration occurs through a cake of constant ...
