Description
Pregelatinized starch is extensively used as an additive to prevent
the seepage of soil filtrates into the wells by increasing the
viscosity of the drilling mud and reducing the fluid loss by
sealing the walls of the borehole. VISCO Pregelatinized starch
helps drills reach further and run freely, control fluid loss,
provide temperature stability and maximize solids removal and
hydraulic efficiency.
It is a Non-ionic natural polymer and highly effective in all
waters including fresh-, sea, saturated salt water, calcium
chloride or potassium chloride or any other brine based system.
High quality biocide added to resist against bacterial and
enzymatic degradation.
Our pregelatinized starch meets or exceeds API *3A
specifications.
Applications / Advantages:
1) Pregelatinized starch is extensively used in
oil well drilling to reduce the fluid loss.
2) Effective in a wide range of make-up water,
including high hardness and high salinity brines.
3) It is used to stabilize rheology and to reduce
the filter cake permeability.
4) It helps to keep drill bit cool and lubricate,
remove the rock fragments or drill cuttings from the drilling area
and transport them to the surface.
5) It provides well bore stability through
filtration control.
Starch Source:Corn, Tapioca or Potato
