It is a high-quality water-soluble cellulose derivative. In shape of white or light yellow free-flowing powder, it is odorless, tasteless, non-toxic & non-fermented, and has good thermal-stability and high salt resistance. It is soluble into water to form thick liquid, and it widely used in water-base drilling fluid so as to enhance the drilling fluid viscosity and control the fluid loss. It meets API international standard.
PAC-HV widely used in water-base drilling fluid for a variety of applications, such as filtration control, viscosity and shale inhibition.
PAC LV is a premium grade purified low viscosity, water soluble polyanionic cellulose, designed to reduce API filtration rate to water-based drilling fluids
- Very effective filtration controller in non-dispersed systems
- Minimal viscosity contribution
- Resistant to micro-bacterial attack without biocides
- Applicable over a wide range of fluid types
- Contributes to shale stabilization
CMC LV is a low viscosity technical grade dispersible Carboxymethyl Cellulose fluid loss additive designed to reduce API filtration rate with minimum increase in viscosity in water-based drilling fluids.
CMC LV (Carboxy Methyl Cellulose) is a modified cellulose and is used to improve the Fluid Loss control of water base muds without increasing the viscosity.
It is used to prevent fluid invasion of permeable zones, and to prevent loss of circulation during drilling, workover, and completion activities. CALCIUM CARBONATE is applicable in all drilling fluids, aqueous and non-aqueous. It can be used to prepare a pill for spotting purposes.
CMC HV is a carboxymethyl cellulose (also carboxymethylcellulose or carboximetilcelulosa) with high viscosity which used for reducing fluid loss and increasing viscosity of drilling muds. oil drilling CMC HV is especially suitable for low-solid drilling fluids.
- Effective filtration controller for aqueous drilling fluids
- Increases viscosity and can be used in salt-saturated systems, performing best when chloride concentrations are less than 60 gal (227 L)
- Compatible with most common mud chemicals
- Can have a deflocculating effect in seawater systems
A drilling-mud additive used to control fluid loss in water muds ranging from freshwater to saturated-salt to high-pH lime muds.
Starches have thermal stability to about 250°F [121°C]. They are subject to bacterial attack unless protected by high salinity or bactericide.
