Oil and Gas Exploration
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 and seismic data was used. By utilizing independent procedures, it was possible to control the process of creating a spatial interval velocity model in locations where no boreholes are present. These models were utilized to conduct PreSDM for improving the imaging of geological strata associated with oil and gas deposits. This problem is considered crucial for enhancing the effectiveness of oil and gas exploration efforts in the transition zone between the Carpathian orogen and the Miocene foredeep.
