Abstract

A method of performing an oilfield operation about a wellbore penetrating a subterranean formation. The method involves performing a fracture operation comprising injecting fluid into the formation and generating fractures about the wellbore. The fractures form a fracture network about the wellbore. The method further involves collecting during the performing data comprising injection temperature and pressure, generating a fluid distribution through the fracture network by performing real time simulations of the fracture network based on the collected data (the fluid distribution comprising temperature distribution), and performing a production operation comprising generating production based on the temperature distribution.
