Polyanionic Cellulose in Oil Drilling Industry and Mining

Polyanionic cellulose (PAC) is soluble in water, has excellent salt resistance, calcium resistance, magnesium resistance, and reduces filtration loss. It can be used for different drilling/completion fluids, especially brine, seawater and saturated brine drilling fluids, which can reduce filtration.

Polyanionic cellulose PAC low viscosity (PAC LV) can be used in different drilling/completion fluids, especially in brine drilling fluids, seawater drilling fluids and saturated brine drilling fluids. Because PAC has excellent solubility in water, excellent salt tolerance and reduced filtration loss.

The slurry with polyanionic cellulose PACwill form thin and hard low permeability filter cake to reduce water loss. Adding PAC into the mud will cause the drill bit to have a lower initial gel strength, allowing the mud to release the internal gas and to put the waste into the mud pit. Like other suspended dispersions, the existence time of drilling mud is stable and prolonged after adding PAC.

Pastes containing PAC are seldom affected by bacteria and do not require high PH or corrosion resistance. The slurry with PAC has excellent stability and can still reduce filtration at 150 C or higher. Polyanionic Cellulose in Oil Drilling Industry and Mining
