3.2.1.1 Bilinear Flow Analysis in FCHF

If the production is taking place from wells with FCHFs, flow patterns appear as Fig. 3.3 in the HF and its surroundings. At the beginning of the production flow, the linear flow of the fracture is formed according to Fig. 3.3a and then, as the pressure pulse of the bilinear flow continues to propagate, it is formed as Fig. 3.3b in the reservoir extent. At the end of the bilinear flow regime, the linear flow pattern of the formation appears towards the HF as Fig. 3.3c, and ultimately, with increase in the propagation of pressure-drop pulse in the well and reservoir system, pseudo-radial flow regime according to Fig. 3.3d is seen around the HF.
