Brazil 2D GeoStreamer

Regional PSDM lines providing the well ties of the major presalt hydrocarbon discoveries in Brazil
Website Map for Survey MCS Brazil 2D GeoStreamer
Brazil 2D GeoStreamer is a high-quality imaging, PSDM survey offering a powerful tool for regional interpretation, calibration and understanding of the main petroleum system elements of the Brazilian presalt play in both Santos and the frontier deepwater Campos area.
This 2D survey ties the main presalt and postsalt discoveries in Santos (e.g. Mexilhão, Lula, Tupi, Sapinhoá) to the other highly prospective areas covered by PGS PSDM surveys. It could be interpreted in conjunction with similar GeoStreamer survey in Africa counterparts
A dual-sensor GeoStreamer 2D PSDM volume providing a high-quality seismic data together with the better understanding of the petroleum systems and regional to sub-regional calibration for 3D interpretations, mainly of the presalt play, in the Campos/Santos basins and its African conjugate basins.
