Case Study: Offshore Southeastern Brazil Basin Study
Overview
Based on the Brazil '99 and Brazil 2000 2D multiclient seismic surveys and available to data licensees, the study spans three offshore Brazil basins: Santos, Campos and Espírito Santo. The interpretation also utilizes information from concurrently acquired gravity and magnetic data.
Digital interpreted data
The study includes three digital file types in ASCII format: edited contour files, seismic line interpretation (horizons and faults), and gridded surfaces in TWT and converted to depth.
The table below indicates the interpreted time data available by horizon. Three key isotimes/isopachs are also included for each basin: salt, seabed to top salt, and base salt to basement.
