Abstract
This invention relates to petroleum industry, in particularly, to control and monitoring of processes related to reservoir stimulation. A method of real time diagnostic of fracture operations with combination of tube waves and microseismic monitoring, comprising performing a fracture in a wellbore, recording microseismic activity generated during the fracturing operations. Determining of microseismic event locations, generating low frequency pressure waves (tube waves) near the wellbore, recording of tube waves reflections from the fractures in real time and analyzing microseismic event locations and tube waves reflections from the fractures.
