Stanley V Stephenson, Jim B Surjaatmadja: Fracture monitoring using pressure-frequency analysis. Halliburton Energy Services, Robert A Kent, C Clark Dougherty Jr, September 5, 2006: US07100688 (19 worldwide citation)

Changes occurring downhole during a fracturing process can create or reflect pressure signals. Capturing and evaluating such pressure waves during fracturing enables personnel to monitor, in real time or later, what happens downhole. When a fracture extends, a burst of acoustic noise is embodied in ...
