Revival of legacy land seismic surveys using advanced processing technologies: an example from the Carpathian foothills
Back to Technical ContentTwelve multi-source/multi-receiver land surveys from the Carpathian foothills were reprocessed and merged using the most advanced signal processing and imaging technologies. These included an innovative denoising subtraction using a primary model from the de-migration of a clean reflectivity from PSDM as well as a high-end surface consistent deconvolution taking into account the heterogeneity of signal across the different surveys acquired with dynamite, vibroseis and airguns. A high-end velocity model workflow was followed using MWI, Tomography joint FB/RMO, HD Multi-Layer tomography and TL-FWI and an RTM was performed with enhanced weighted azimuthal illumination to accurately image the deeper subsurface.
