<p>A method for monitoring movement of a hydraulic fracturing fluid through a subsurface formation includes measuring at least one of a pressure and a temperature of a fluid using an optical fiber sensor disposed in at least one wellbore drilled through the subsurface formation at a selected position away from a location wherein the hydraulic fracturing fluid is pumped into the subsurface formation. A position of a fracturing fluid front is inferred using at least one of the measured pressure and measured temperature.</p> |
