Abstract

A few volumes of the water that exist in the cement slurry may be absorbed by the formation due to enough pressure and temperature exerted on it. This phenomenon can lead to miss-hydration. Filtration control additives are used to bridge the porous media and prevent liquid migration across it. Insufficient filtration control may cause gas migration. In this area, there are many effective parameters but the free water and filtrate volume are essential. In this article, for controlling the filtrate volume, after studying different additives with different formulation, it was tried to couple a powder FLC with a liquid one. The results had a good effect on rheological properties and decreased the transition phase between liquid and solid behavior. The filtrate volume was controlled at 1000 psi between 150F and 180F. The rheological characteristics were controlled in the API range. The mixing time was decreased and the free water was omitted.
