Abstract

We present a time reverse mirror approach for estimating hydro-fracture source locations. With this scheme, the passive seismic data generated by the hydro-fracture sources are crosscorrelated with the wavefield extrapolated from the VSP or seismic while drilling data, and the image shows the location of hydro-fracture sources. Only an estimate of the local velocity v (x, z) model around the VSP well is needed and this method is robust with respect to noise and limited source and recording apertures. Synthetic tests with the SEG/EAGE salt model demonstrate the potential for its use with enhanced oil recovery operations.
