摘要： A method of completing a wellbore that includes providing wellbore casing having shaped charges and permanent pressure gauges on an outer surface of the casing. In an example of use, the casing is inserted into the wellbore and cement is injected into an annulus formed between the casing and wellbore. The shaped charges are strategically deployed on the casing so they aim towards a wall of the wellbore and are spaced apart along the casing. Thus detonating the shaped charges creates perforations into a formation around the wellbore and places the pressure gauges into pressure communication with the formation. Pressure readings are delivered to the surface from the pressure gauges in the form of signals.
