Modified Starch For High Temperature (140ºC) SHR-1
Product Description
SHR is an environmentally friendly, low-viscosity filtration reducer with excellent salt resistance (up to saturation). It has been modified with starch by incorporating hydration groups and a high-temperature stabilizer to enhance water solubility and temperature resistance (up to 140 ºC), ensuring optimal fluid loss performance under both low and high temperatures. The recommended dosage is 3.0 - 7.0ppb.

Features
Perform well up to 140 ºC.
It is degradable, non-toxic and does not harm the environment.
Increase viscosity slightly.
Reduce filtration loss effectively.
Resist salt to saturation, reasonable calcium and magnesium resistance. so it can be applied in various drilling and completion fluids.
Good filtration control performance under the condition of both low and high temperature, and has wide applicable temperature range.
