2015-6-25 Neat cement slurries normally exhibit an uncontrolled API fluid loss of at least 1,500 cm 3 /30 min. This value is excessive for most cementing operations, where permeable formations are encountered or where long columns of cement will be used. The amount of fluid-loss control required for a particular operation varies widely, and is largely

2022-9-13 Excessive fluid loss will reduce slurry volume and give less cement fill. When squeeze cementing it is desired to get an effective squeeze against the entire formation and not just squeeze cement filtrate into it. Most fluid loss additives tend to viscosify the slurry and consequently, dispersants are often added at the same time to control
