... and quantitative compensation based on reflection wave is proposed. Firstly, the reflection wave in the specified time window is used to calculate the centroid frequency of source and receiver points. Next, after offset correction, combined with the surface travel time, the frequency shift method is used...

... on this, a set of 3D converted wave static correction method is proposed. In this method, P-wave shot point statics are directly used as the static correction of converted-wave shot points. The calculation of converted wave receiver point static correction is gradually solved by three methods: P wave and S wave...

... acquisition. Many source and receiver points in the pre-designed program have serious deficiencies because of safety and obstacles, resulting in not only parts of the shallow layer data loss, but also the incomplete data in the interesting layer. For the source and receiver points deployed at the dock...

.... Introduction The depth of dynamite shooting varies from several meters to dozens of meters generally, so the shot and receiver points are not at the same datum. This may result in obviously unreasonable delay time using the Generalized Reciprocal Method (GRM) or iterative method. For GRM method, reciprocal...
