RESOLVING STATICS RELATED PROBLEMS IN THE AMAZON BASIN

In a seismic survey, shots and receivers are planted at different locations with different elevations above an established datum. The travel time to the same subsurface horizon is shorter for a wave generated by a shot detonated at a lower elevation than one at a higher elevation. The case is similar for receivers. It is fundamental to remove these surface effects from the seismic data, so that all the data "appears" to have been acquired on the same horizontal plane. These time shifts are called static corrections.
