    In Department of Fossil Fuels at Technical University in Kraków seismic data reprocessing was made and dynamics and resolution of seismic data was improved. It was part of broad Polish-Ukrainian project which aim was to investigate new hydrocarbon reservoir in Polish-Ukrainian Carpathian. In this essay investigation area was confined to sigmoid tectonic element near Przemyśl. Complicated structural conditions and low quality of seismic data made this difficult. Because of this, careful seismic data processing workflow was prepared and included: static correction, prestack depth migration and time-depth conversion. Long wave static was computed by refraction wave tomography method. Prestack depth migration was used to improve quality of imagining. Velocity model for migration and time-depth conversion was prepared as common 3D cube for all 2D seismic lines combining seismic velocity, structural maps and well logs.
