Wiper plug perforating system

A method of cementing and perforating in a subterranean formation comprising:

• providing a perforating gun system having a perforating gun with shaped charges, a plug on an end of the system, and a flexible member connected on an end to an end of the perforating gun and on a distal end to the plug;
• injecting cement into casing inserted within a wellbore;
• deploying the perforating gun system into a wellbore and oriented so that the plug is inserted into the wellbore before the perforating gun;
• applying a pressurized fluid on a surface of the plug facing the perforating gun to push the perforating system within the wellbore and thereby urge the cement through a lower end of the casing and into an annulus between the casing and the wellbore;
• locating the perforating gun system at a location in the wellbore;
• detonating the shaped charges in the wellbore;
• detaching the plug from the perforating gun;
• and
• removing the perforating gun from the wellbore.
