Fluid loss Control Polymer

DosFL™ D composition contains synthetic polymer which is useful in controlling the fluid loss rate. Extensive testing has been performed and the results showed that overall performance of DosFL™ D remained good with many cement additives.


·     At a concentration of 0.5 %BWOC, DosFL™D can control ISO/API fluid loss rate to 42 ml/30 min.

·     DosFL™D has combability with GasStop™ 3000 (DOSAS Gas Migration Control agent) to control annular gas migration.

·    The filtration rate decrease owing to the plugging of pores within the cement filtercake by the DosFL™D small particles.

·     DosFL™D forms a hard and cracked filtercake with 42 mm thickness.



·       DosFL™D was developed for primary or squeeze operations.

·       In most cements, DosFL™D concentrations of 0.5 %BWOC or less provide adequate fluid-loss control.

      ·        DosFL™D fluid-loss additive was evaluated at bottomhole static temperatures (BHSTs) between 160 °C and 138 °C.
