Image post- and presalt targets to improve your prospectivity assessments and field development decisions
WesternGeco, in a joint venture with TGS, has more than 9,000 km to assess exploration plays in the 16th bid round. This includes blocks in the central margin of Brazil covering the Camamu-Almada and Jequitinhonha Basins. The coverage of the 2D data provides a regional framework to help understand the complex subsurface structural picture and assist with initial exploration approaches.
The 6th presalt auction and 16th bidding round blocks in the Santos and Campos Basins have structural and stratigraphic complexities that require high-quality seismic imaging technologies to illuminate key structural features of the reservoir. WesternGeco, in a joint venture with TGS, has more than 127,000 km of prestack depth migration (isotropic and TTI anisotropic) 2D data available in the southeastern margin of Brazil, covering the Santos, Campos, and Espirito Santo Basins.
Within the presalt polygon of Santos Basin, we have acquired high-definition 3D surveys. These high-definition, 4D-ready surveys cover approximately 10,595 km2 of the Santos Basin and include prestack depth migration final volumes. The high-density acquisition (50-m cable separation), acquisition direction, and intrasalt tomography help you overcome the challenges of presalt imaging. The high-quality image achieved from these processes enable a more confident subsurface evaluation, leading to more effective exploration, appraisal, and drilling decisions.
