The closure phase principle was used in estimating static shifts in seismic data. In areas with complex topography, the static shifts usually caused by lateral variations in sediment thickness and/or velocity of the near-surface layers will distort the continuity of seismic events. More seriously, it introduces false structural anomalies. In this report, we develop a new statics correction meth...

Both migration deconvolution (MD) and least squares migration (LSM) are capable of improving the resolution and suppress acquisition footprints in migrated images. In this report, I investigate the relative performance of these two methods in enhancing migration image quality, suppressing artifacts and computational efficiency. Both MD and LSM were implemented on synthetic data generated from p...

In areas with complex topography, the static shifts caused by lateral variations in thickness and/or velocity of the near-surface layers will distort the continuity of seismic events. More seriously, it will introduce false structural anomalies. In this report, a static correction approach, which does not require estimation of the near-surface model, is developed based on the closure phase prin...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....
