Delineation of Subsurface Structural Geology in Buzrgan Oil Field Using 2D Seismic Interpretation

Abstract

This study focuses on the structural picture interpretation of Buzurgan oil field in the Maysan province of southern Iraq. Using 2D seismic data, Synthetic traces are created by selecting reflectors on the seismic section using the Petrel software and the well (BU-1) data currently available. The reflectors represented Paleocene to middle Miocene, which are L-Fars-Kirkuk-Jaddala-Aaliji. A thrust fault that solely impacts the L-Fars formation is dividing the research region into two blocks that are each affected by the examined reflectors. The fault system extends from northwest to southeast. The structural interpretation of depth maps reveals that some anticline folds were localized roughly surrounding well locations were marked on all maps.
