The subject of the study presented is a process of acid treatment of a fracture generated by FHF using proppant in carbonate reservoirs. For prediction of acidizing treatment effectiveness the averaged mathematical model of this process was developed based on the laws of acid mass conservation and acid transport in fractures taking into account the acid solution leakage due to diffusion towards the treated surface. The modeling aids in the pressure field predic-tion, as well as the acid concentration profile along the fracture and the fracture width variation resulted from the face etching, and the skin factor as a function of injected acid amount and injection rate.
