Abstract

Recording point receivers or point sources instead of the conventional receiver or source arrays enables individual corrections to be applied before Digital Group Forming (DGF) to compensate for:<br>- Static variations due to different weathered zone conditions or elevations between the different receivers or sources of the same group,<br>- Amplitude variations due to different coupling conditions,<br>- Move-out differences at far offsets.<br>In addition, a finer spatial sampling of the point receiver or source spread along the inline and crossline directions improves the filtering of source generated surface noise.<br>A field test of the point source and point receiver methods was performed in 2006 by inserting a point source line and a point receiver line within a “conventionalâ€ 3D survey acquired with source and receiver arrays. The objective was to allow a fair comparison of these two test datasets with reference array datasets acquired with equivalent fold and geometry.
