A11 WHAT IS THE “POINT” OF HIGH-RESOLUTION 2D 2 880-CHANNEL ACQUISITION? Abstract 1 A 2D high-resolution 2 880-channel seismic crew has recently operated in Saudi Arabia for 3 years. The initial single-source line/single-receiver line configuration with “point” receiver arrays (all-pass spatial filter) recorded low signal-to-noise seismic shot gathers which were difficult to enhance in processing resulting in poor seismic imaging. Through uncorrelated noise-strip and synthetic modeling analysis it was confirmed that unfiltered back-scattered energy and coherent/random ambient noise sources were primary causes of degradation of the seismic images. Subsequent in-field acquisition testing revealed that the in-line spatial sampling could be
