WebKirchhoff PSDM before and after high resolution statics correction is applied to the input data. Note that the dip of the event shown in Figure 7a is greatly reduced in Figure 7b. This is consistent with the well information. Conclusions . The improvements to the imaging were accomplished by WebI have a geophysics master degree and bachalor mathematics bachelor degree. I have worked in data processing (PSDM) at Petroleum Geo-Services (PGS) since november 2011. Basically I have to work on velocity model building (VMB); kirchhoff migration and post-processing. During VMB I run some tomographies to get flatter gathers and geological …
