HOUSTON -- ION Geophysical has completed the first phase of its BrasilSPAN seismic data program and delivered the processed data, seismic images, and an integrated interpretation.
BrasilSPAN comprises of 12,000 km (7,456 mi) of seismic data that images the entire crustal section in Brazil's Santos, Campos, and Espirito Santos hydrocarbon basins. ION worked closely with regional experts to design the survey and tie the acquired seismic data lines to critical wells in the basins of interest. The program was acquired with long offsets, long listen times and imaged with proprietary reverse time migration (RTM) technology from ION's GX Technology (GXT) seismic imaging subsidiary to provide improved resolution in the pre-salt and salt flanks, the company says.
BrasilSPAN was planned in partnership with ION's AfricaSPAN customers in order to address questions of interest to global exploration teams, including how the conjugate ties between West Africa and Brazil affect the exploration potential along the continental margins on both sides of the present-day Atlantic Ocean.
The regional, conjugate, and interpretative studies that are part of the BrasilSPAN program will assist in providing an understanding of the mechanism for the break-up of the continents, help develop and de-risk exploration play concepts, and provide a framework to characterize the hydrocarbon potential along the offshore margins of both West Africa and Brazil, the company says.
