Abstract
In one aspect, a wellbore system is disclosed that in one non-limiting embodiment includes a cement section in the wellbore formed to prevent flow of fluids including hydrocarbons through the cement section, a plug disposed uphole of the cement section to provide a space between the cement section and the plug and a sensor in the space for providing measurements relating to a parameter of interest. In one aspect, the parameter of interest may include one or more of presence and extent of a hydrocarbon, presence of moisture; pressure; and temperature. The system may further include a transmitter that transmits measurements from the sensor via a communication line or wirelessly to a receiver for processing the sensor measurements.
