Smart Frac Plug System and Method

Abstract

A frac plug system for use at the end of well drill string in a fractured underground formation, includes 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; a set of sensors positioned on said nose cone, said set of sensors being selected from a group including: temperature sensors, pressure sensors, pH sensors and fluid composition sensors; a battery operated microcontroller located within said mandrel body, said battery operated microcontroller constructed and arranged to periodically read the data output of said set of sensors and store said data from said set of sensors; a transmitter electrically connected to said battery operated microcontroller, said transmitter constructed and arranged to transmit said stored data from said set of sensors to a receiver 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; and whereby when said data from said set of sensors may be retrieved from said electronic memory.
