Description
POLYTROL® is a new generation organic polyamine shale inhibitor – ether amines. It is a key inhibitive ingredient of the new HPWBM - high-performance water-based muds. This type of mud has comparable inhibitive properties to oil-based mud (OBM).
It is a mildly cationic terpolymer. Positively charged POLYTROL® molecules adsorb onto the negatively charged planar surfaces of clay particles leaving no place available for water molecules.
With regards to inhibitive properties, POLYTROL® based drilling fluids greatly surpass KCl/PHPA muds and more closely resemble the invert emulsion drilling fluids.
Applications/Functions
- clay mineral hydration inhibitor (illite, chlorite, kaolinite, smectite)
- ensures integrity of the wellbore wall and cuttings, prevents from desintegration
- coats metal surfaces with the protective film, prevents bit and BHA balling, improves ROP
- is a main component of HPWBM – cost effective and environmentally friendly OBM alternative
Advantages
- unlike KCl does not negatively influence logging results
- unlike KCl – less transportation and storage costs
- unlike KCl does not harm the environment
- minimal impact on the reservoirs, recommended to use in drill-in fluids (reservoir drilling fluids)
Recommended treatment
1-1,8 ppb (3-5 kg/m3)
Typical properties
Liquid
Handling

Packaging
POLYTROL® polyamine shale inhibitor is packaged in 55-gal (208 l) drums
