Abstract
This application relates to methods and apparatus for monitoring hydraulic fracturing in well formation and fracture characterization using distributed acoustic sensing (DAS). The method involves interrogating a optic fiber () arranged down the path of a bore hole () to provide a distributed acoustic sensor and also monitoring flow properties of fracturing fluid pumped () into the well. The acoustic data from the distributed acoustic sensor is processed together with the flow properties data to provide an indication of at least one fracture characteristic.
