A New Approach of Parameters Identification from Fluid Flowing Back after Hydraulic Fracturing

Reservoir and fracturing parameters are essential to evaluate well production after fracturing treatment. Conventional technologies to get these parameters are costly in both an absolute sense and in possible temporary loss of production. In this paper, we present a new technology to acquire parameters from the fracturing fluid flowing back process. The technology includes a new mathematical model and a new numerical method. The model considers the situations of a variable flow rate and different boundaries. This technology can reduce cost and time, and put the fractured well into production ahead of time.
