NSM building and statics estimation for Block B in Saudi

We finished the near surface model building and statics estimation for Block B in Saudi during the three years of 2007 to 2009. The adaptive constraint tomography inversion was adopted, in which the upholes, the stiffness and viscosity attributes of vibrator, the geology and geomorphology map of surface, and the first arrivals were integrated. The following seismic data processing is based on the statics of our new model for this block.
