Advanced Depth Imaging Technologies: A case study in Carpathians Foothills

In this paper we will focus on the resolution of the strong imaging challenges of the area. First, we will show how the combination of Multi Wave Inversion (MWI), joint First Break (FB) and slope tomography, and Full Waveform Inversion enabled to construct a high resolution near surface velocity model which solved the important distortions caused by the varied terrain and rough topography. Then we will give insight on an advanced Multi Layer Tomography workflow complemented by TL Full Waveform inversion. It enabled to finely capture the strong lateral and vertical velocity contrasts of large thrust, thus enabling to restore the focusing and faulted structure of the Jurassic reservoir units underneath
