Abstract

Summary

Ultra high density Full-Azimuth land acquisition has become possible in recent years thanks to significant advancements in recording systems, the introduction of simultaneous sourcing acquisition techniques ( ) and the move towards point source, point sensor configurations. While the benefits of high density acquisition are not in doubt the costs are still significant. Hence there is a strong requirement to understand the effort / benefit relationship when moving to high density acquisition. Such data can also bring challenges and opportunities for seismic processing and imaging ( ). In this presentation we take an ultra-high fold test dataset and decimate to simulate 20 different acquisition sub-sets. By carefully designing a processing sequence to process the data consistently between the datasets, it is possible to understand how shot and receiver sampling for each configuration affects processes such as noise attenuation, surface consistent processing, velocities, the final imaging and attributes.
