Abstract:
The sources of microseismic hydraulic fracture events ("hydro-fracs") are located for image mapping by the calculation of Green's functions G(x, z, t|x', z', O) which is estimated using, e.g., RVSP, VSP, SWD and/or surface data, with the Green's functions used as migration kernels with greater accuracy than the prior art techniques, e.g. the diffraction limit, because all of the natural arrivals in the data are utilized.
