The subject this research is presentation of the seismic processing procedure focused on creating and validating interval velocity models typically used in PreStack Depth Migration (PreSDM). For the validation of interval velocity, simultaneous inversion has been applied. All geophysical and geological data were used as constraints. The survey area is located in the Carpathian overthrust in close proximity to well-known hydrocarbon deposits. In the research, the method of simultaneous inversion (SJI) of gravity an...

Hydrocarbon deposits in Polish Carpathians occur at rather shallow depths, but under highly complex structural and lithological conditions. It is therefore much difficult to detect and recognize such deposits with use of surface geophysical methods. The research works have made since 2008 year led to investigations of the Grabownica oil and gas field with use of electromagnetic methods: Audiofrequency Magnetotellurics (AMT), Controlled Source Audiofrequency Magnetotellurics (CSAMT) and Induced Polarization (IP).
