Főoldal > Products > CMC HV/CMC LV

Carboxymethylcellulose (CMC) is the most popular drilling polymer. It is used as viscosifier and fluid loss reducer in different types of water based drilling fluids. Non toxic, natural cellulose based polymer.

Application/advantages:

TiKEM CMC HV:

– Can be used in various type of drilling fluids (fresh water to salt water)

– Can be used to substitute part of bentonite to keep solid content low

– Good rheolgy control, filtration control

– Formation thin cake, protection from flocculate

– It should be added slowly through a mixing hopper at a rate of 10-20 min/sack

TiKEM CMC LV:

– Can be used in various type of drilling fluids (fresh water to salt water)

– Can be used when lower viscosity product is highly recommended for the control of fluid loss (p-e. at higher mud weight)

– Good microbial susceptibility

– Can be used at wide range of pH (6-12)

– Can be used at deep condition (lower than 300m)

– It should be added slowly through a mixing hopper at a rate of 10-20 min/sack

Dosage:

– in case of fresh water mud: 3-9 kg/m3 water

– in case of bentonite mud: 2-4 kg/50 kg bentonite
