Abstract

A method of servicing a wellbore, comprising placing at least one piece of equipment in the wellbore comprising micro-electro-mechanical system (MEMS) sensors, wherein the MEMS sensors are disposed in one or more composite or resin portions of the equipment, and gathering wellbore data from the MEMS sensors. A method of servicing a wellbore, comprising placing at least one piece of equipment in the wellbore comprising a micro-electro-mechanical system (MEMS) sensor data interrogation unit, wherein the data interrogation unit is disposed in one or more composite or resin portions of the equipment, and gathering wellbore data from MEMS sensors located in the wellbore via the data interrogation unit.

Claims
