Drilling starch is a polymer derived from the unmodified starch including amylopectin content. This starch has fermentation stability and it gives enhanced high temperature fluid loss performance when working in combination with drilling fluids. It has optimal use in all water-based drilling, stimulation, and completion fluids.
Usage:
-Apt for drilling, work over or completion of fluid
leakage
- Control additive appropriate for utilization at high
temperatures
- Keep up liquid loss control at up to 300F (150C),
helps in stabilising rheology
- Does not ferment Treatment rate, Typical, 1-4 ppb,
as essential to control liquid loss.
- Higher temperatures (above 150C) may be
necessary to activate HT Starch to supply effective
rheology and fluid loss control totally as a binding
agent.
