Smart frac plug system and method

A frac plug system for use at the end of well drill string in a fractured underground formation, said frac plug system comprising:

• an elongated mandrel body, wherein the front portion of said elongated mandrel body includes a nose cone, the rear of said elongated mandrel body includes a mandrel head and the mid-portion of said elongated mandrel body includes a sealing assembly;
• at least one sensor positioned on said nose cone;
• a battery operated microcontroller located within said mandrel body, said battery operated microcontroller constructed and arranged to periodically read data output of said at least one sensor and store said data from said at least one sensor;
• a transmitter electrically connected to said battery operated microcontroller, said transmitter constructed and arranged to transmit said stored data from said at least one sensor to a receiver configured to be located in a pup joint when said receiver is in receiving range of said transmitter, said receiver constructed and arranged to write said transmitted stored data to an electronic memory;
• whereby said data from said at least one sensor may be retrieved from said electronic memory.
