Abstract

The object of presented study is a process of fractured carbonate reservoir acidizing. For the assessment of acidizing the induced fractures from the hydraulic fracturing with proppant, the averaged mathematical model of this process was developed. The model is based on the laws of acid mass conservation, acid transportation in fractures considering acid diffusion towards the treated faces. The model is constructed for prediction of pressure field, flow field, acid concentration profile along the fracture and fracture width variation due to face etching as a function of injected acid volume and injection rate.
