Description: a chemical agent based on acrylamide derivative.

Application: for effective reducing water loss of cement mortars in technological processes of well casing.

Recommended discharge: 0,15–0,50% by weight of dry cement for effective reducing a filtration index; 0,60–0,80% by weight of dry cement as an agent for prevention of behind-the-casing migration of formation fluids. The concentration should be selected according to a particular recipe and parameters.
