A numerical model of a polymer-based fracturing fluid displacement from a fracture and a filtrate zone by a formation fluid is provided for calculating a change of a fracturing fluid concentration in a produced fluid and for calculating a change of a polymer concentration in the recovered fracturing fluid. Throughout the entire fracturing fluid recovery the produced fluid samples are periodically taken from a well mouth. The fracturing fluid concentration and the polymer concentration in the samples are measured. The measurement results are compared with the model calculations and the fracture length and width are determined based on a match of the measurement results and the model calculations.
