Abstract: A method for monitoring pressure in a formation traversed by at least one wellbore comprising providing a tubular element having an outside surface, attaching a perforating gun oriented in such a way that when fired, the perforating gun does not damage the tubular element, connecting a sensor to the perforating gun in close proximity to the perforating gun wherein the sensor is exposed to the wellbore, inserting the tubular element into the wellbore, securing the tubular element in the wellbore, firing the perforating gun to penetrate the formation, exposing the sensor to the formation pressure, and monitoring the pressure in the formation with the sensor to obtain pressure data.
