3D Seismic High Productivity Application for Geothermal Development - Case Study in Suburban Environment (Munich Germany)

We present a least-squares inversion solution for Full Wavefield Migration (FWM). The algorithm is capable of imaging all reflection modes in the data consisting of primaries and multiples. The inversion approach is key to improving the resolution of seismic images and compensating for the illumination variations due to incomplete acquisitions. The least-squares method also attenuates the artifacts caused by the crosstalk between different orders of reflections. At its core, the inversion uses a Born modelling kernel capable of propagating the full reflection wavefield from seismic records. The algorithm solves for the earth reflectivity by means of data residual reduction in an iterative fashion. Successful applications to field data from different geological settings demonstrate the effectiveness of the solution in imaging the full seismic wavefield beyond primaries.
