Broadband Seismic Imaging of Thrust Belt along the Outer Banda Arc in Indonesia

3D broadband seismic technique and appropriate PrSDM imaging technique provided us significant improvements in seismic imaging for both thrust complex and sub-thrust structures. Broadband 3D seismic imaging contributed better recovery of seismic energy from deep sections where conventional seismic imaging could not reveal any reflections. Pre-migration deghosting technology provided us the stable phase of wavelets and desired broadband frequency spectrum in the seismic image. The velocity model constructed from the combination of Kirchhoff PrSDM and Controlled Beam Migration provided better resolution and continuity of seismic images under thrust complexes and large fault surfaces by overcoming the poor illumination issue. These technologies contributed to revealing subtle fault displacements, reducing depth structure uncertainty below thrust complex and increasing the understanding of petroleum systems and risk elements of exploration target in a frontier region.
