SuperCache  GOM 2D​

SuperCache dataset is the foundation dataset of DDS’s data library. It is 10,000 miles of proprietary, ultra-long-offset, deep penetration 2D PSDM data (SuperCache, 2012) in the US GoM, acquired predominantly in deep water, covering the entire basin from Texas to Florida.  It is the industry's first application of 15km offset cable and 9,100 cu.in source to provide adequate penetration. The Moho is evident through much of the data set, demonstrating the full crustal signature. The oceanic crustal architecture and limit of the oceanic crust is clear and diagnostic, and rifted continental crust is evident in a variety of different thinning configurations around the basin. Comprehensive interpretation and collaboration is included in data deliverables to enable work-station ready integration.
