Abstract
An illustrative fracture mapping system includes: a data acquisition unit collecting measurements deformation measurements during a fluid injection phase of a hydraulic fracturing operation; and a processing system implementing a formation mapping method. The formation mapping method includes: obtaining an initial fracture map having a location and geometry for one or more fractures activated during the fluid injection phase, the fracture map corresponding to a given time during the hydraulic fracturing operation; deriving from the initial fracture map a time series of fracture maps for times preceding the given time; and storing the time series on a nonvolatile information storage medium. The deriving may be performed in an iterative fashion to obtain each fracture map in the time series from a subsequent fracture map.
