The main function of drilling hydraulic mixtures is to lubricate the drill bit and casing, as well as to remove pieces of rock. Na CMC is added to the fluid loss control agent in the surrounding formation. As a binding agent, Na CMC improves the suspension of rock pieces and ensures low liquid friction of the pumped viscosities.
Compared to natural polymers (starch, for example), Na CMC has advantages:
- dissolves in water;
- the viscosity is achieved with less;
- biostability is higher.

In comparison with technical polymers or polymers of crude grades of cellulose base, to achieve the required properties, especially control over fluid loss, requires significantly less of them.

A lesser degree of supplementation confers the following privileges:
- cost reduction;
- lower levels of chloride, which leads to a lower degree of corrosion;
- reduced transportation and handling costs;
- smaller storage capacity is required on drilling rigs;
- high efficiency of the use of saturated salt water in the sea and sea mixtures;
- no risk of clumping in very wet areas.

Modern drilling fluids are increasingly facing more stringent environmental controls. CMC and PAC are water-soluble polymers derived from cellulose. They are eco-friendly, fully biodegradable and non-toxic. Therefore, they can be used all over the world without restrictions.
