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.
Benefits:
· 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.
Applications:
·
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.
