loss additive for cement

Cement slurry fluid-loss-control additives (FLAs)

 · 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 ...
