In this work, we propose a technique for High-Resolution Velocity construction based on Amplitude Inversion combined with Dynamic Auto Correlation or Dynamic Time Warping. The main aim for this workflow is to provide a High-Resolution velocity field that can be used as an attribute in data interpretation and classification. Synthetic examples show that the algorithm can reconstruct the P-wave velocities from log data in the case of no anisotropy. We demonstrate cases of constructed velocity field’s implementations for lithology, pore pressure and reservoir highlighting. Taking into account that technique does not require big computation resources, that makes it a convenient seismic interpretation attribute.
