Proppant coating

Evonik supplies a line of superwetting surfactants that have been used as slow released wetting agents for the control of formations damage caused by water. Porous ceramic proppant is used as a carrier to deliver our Arosurf super wetting surfactants downhole and maintain interaction tension low on a long-term basis, hence improve the long-term production of oil or gas. In addition, or wetting agents are also used in the manufacturing of coated proppants.
