The HydraCap encapsulating additive is a low-molecular-weight, dry acrylic acid copolymer that provides excellent cuttings encapsulation by adsorbing onto the clay surfaces and forming a protective film that prevents cuttings from sticking to each other or the shaker screens. It limits dilution rates and low-gravity-solids loading by preventing clay solid from dispersing into the mud system. This product is effective in a wide range of base brines, including seawater, saturated sodium chloride, and potassium chloride; however, it should not be used in calcium brines. Typical concentrations of the HydraCap additive range between 0.5 and 4 lbm/bbl [1.4 and 11.4 kg/m3].
