Abstract
The article is dedicated to the factors affecting the estimation of the structural uncertainty on the 2D seismic data for the case of no LOG and VSP data on the one of the Caspian Sea areas. Complex seismogeological structure of the near-surface section and high and low-velocity local anomalies affected the structural geometry for the target reflecting horizons — are the key features of project. 2D seismic data was processed and interpreted from 2020 and 2023. During re-processing in 2023, the imaging of time and depth migrated images was significantly enhanced in particular by efficient supervision and interpretive maintenance. The results of the evaluation of the uncertainties of the structural plan for the area of interest were of fundamental importance for the further planning of the methodology of 3D seismic exploration and drilling.
