POLYTROL® (new generation organic polyamine shale inhibitor)

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).

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

Please refer to the MSDS for specific instructions

Packaging

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