The Responses of Injection Pressure and Fracture Width during Height Extension in Sand-Mud Interbed Reservoirs in the Dongsheng Gas Field

Figure 18

Height growth process in the reservoir with asymmetric mud interlayers: (a) height extends to the first interface, (b) height breaks through the first interface, (c) the lower branch breaks through the mud interlayer and extends to the lower cap, and (d) the upper branch extends to the upper cap.
