Abstract

Ultrahigh-resolution 3D (UHR3D) seismic systems employing a dense array of short streamers represent a significant advancement in the field of marine seismic data acquisition and are an appropriate choice for many near-surface survey applications. Data comparisons between conventional 3D, reprocessed 3D, high-resolution 2D, and UHR3D seismic data illustrate the benefits of a UHR3D acquisition strategy. Results from a recent study of seeps imaged in the Gulf of Mexico (GoM) suggest that UHR3D data can serve as a comprehensive data source for some near-surface geophysical characterizations, satisfying many of the needs often addressed by integrating multiple separate types of survey data.
