Fluid Loss Reducer

OV-LOSE HT Starch

Anti-high Temperature Modified Starch OV-LOSE HT is modified starch by inserting hydration groups and high temperature stabilizer to improve the water solubility and temperature resistance (up to 130℃). And ensure its good fluid loss performance under both low and high temperature. SHR is an environmental friendly, low viscosity, salt resistance (up to saturation) filtration reducer.

Application & Advantages

Scope of Application:
OV-LOSE HT is applicable for PRD mud system for both reservoir and non-reservoir interval.

‍Key Feature:
Reduce filtration loss effectively.
Increase viscosity slightly.
It is degradable, non-toxic and does not harm the environment.
Perform well up to 130℃.
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.‍

Usage:
OV-LOSE HT can be directly added in drilling fluid at a relatively slow speed. It can also be used to prepare compound solution with other additives for mud treatment or performance maintenance.  Its recommend dosage is 3 - 7ppb.

Application Temperature:
The application temperature of this drilling starch cannot exceed 130°C.
