Project Description

Drilling Starch


Drilling starch is non-ionic corn, tapioca and potato-based polymers for use in all water-based drilling, completion and stimulation fluids. Drilling starch is extensively used as an additive to prevent the seepage of soil filtrates into the wells in all types of water based drilling fluid systems by increasing the viscosity of the drilling mud and reducing the fluid loss by sealing the walls of the Borehole. High quality biocide added to resist against bacterial and enzymatic degradation.

Applications / Advantages:

1)  Drilling 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.


  • It provides Economical Method of filtration Control
  • Can be used in the full range of water types as KCl,NaCl,MgCl2,CaCl2
  • Stabilizes rheology
  • Provides well bore stability and filtration control
  • Non damaging to the formations
  • Contains Preservatives
  • Performs over a wide PH range.

Starch Source: Corn, Tapioca or Potato


The recommended normal treatment ranges from 2-6   lb/bbl(5.7-17.1 Kg/m3) depending on the makeup water chemistry or the Desired Fluid Loss .Higher concentrations are required in brine Systems.
