Abstract

A method for measuring parameters related to wellsite operations comprises mixing Micro-Electro-Mechanical System (MEMS) sensors with a wellbore servicing composition in surface wellbore operating equipment. The MEMS sensors are assigned a unique identified that may be used to track individual MEMS sensor as the MEMS sensors travel through the wellbore and may be used to correlate sensor measurements taken by the MEMS sensors with particular locations in the wellbore. The MEMS sensors may be active and transmit their respective identifiers and sensor data to the surface. Transmitting identifier and sensor data from a MEMS sensor to the surface wellbore operating equipment may be via one or more other MEMS sensors, downhole devices, and surface devices.
