DosFL™ PV-30 Fluid Loss Control Agent
For wells with an open hole or cased hole completions, and for new completions or workovers or interventions, we recommend DosFL™ PV-30 to mitigate losses and avoid formation damage. DosFL™ PV-30 is an excellent binder, reduces fluid loss, reduces water production in the well cementing process, and is compatible with other cement additives. Addition of this additive to slurry results in a reduction of filtration with minimal effect on rheology.
Key Benefits of DosFL™ PV-30:
• Reduces fluid loss during cementing up to 60 °C.
• Exhibits minimal effect on rheology.
• Effective in freshwater, however, limited to salt-saturated environments.
• Efficient with various cement slurry compositions including class G and bentonite extended.
Achieve Reliable Zonal Isolation
Laboratory tests using DosFL™ PV-30 have shown significant reductions in the fluid loss rate of cement slurries. Fluid Loss reduces with increasing concentration, expressed here as a percentage by weight of cement (% BWOC). Acceptable performance is reached at 50 °C with 1% BWOC concentration.
