A compressive seismic field trial and reconstruction test using regular indexing

Abstract

Seismic image quality is greatly impacted by data density, and high-density seismic acquisition can be done more efficiently nowadays by using the Compressive Sensing concept (Candès et al., 2006; Donoho, 2006) in seismic survey design. In order to do a proper Compressive Seismic Acquisition (CS-A) (Jiang et al., 2017) in a real-time production setting, more factors are required to be evaluated or considered compared to a simple synthetic study. In this paper, we present a unique field trial in North America specially designed to evaluate the CS-A in a 3D land survey. The field trial comprises a base survey with conventional design and two scenarios of CS-A designs with different focuses: cost-saving or resolution-enhancing. The Compressive Seismic reconstructions (CS-R) (Jiang et al., 2017) are done for both scenarios and compared to the conventional base survey.
