ION's BasinSPANTM regional 2D programs feature surveys designed for the purpose of imaging the full crustal architecture. Their BrasilSPAN program is showing never before imaged sub-salt horizons and new stratigraphic and structural details of this frontier petroleum system.
Recent news of at least three dry wells and suspension of the Tupi extended well test illustrate some of the challenges facing the pre-salt play that Brazil's government has touted as having "no exploration risk." However, with the huge reserves already discovered, the frontier area remains a hot play.
Covering an area about half the size of Europe, Brazil's onshore basins could hold large quantities of oil and gas like their Northern Hemisphere counterparts. Yet they have remained barely explored, overshadowed by the huge successes in the offshore.
Hidden by a thick veil of salt and once thought too deep for liquid hydrocarbons, recent deep water discoveries off the southeastern Brazilian coast could be the largest in the past 30 years.
The first offshore well was drilled in shallow water in 1968. For the next 30 years, Petrobras has been challenging ocean depths with the innovation and technology that has brought the oil and gas industry into the ultra-deepwater era.
The sub-salt discoveries recently reported in the Santos basin, offshore Rio de Janeiro, Brazil could be the largest in over 30 years and has captured the world's attention.
Gateway to huge offshore oil reserves, Rio de Janeiro and southeast Brazil offers stunning scenery and geologic evidence of ancient mountains and the forces that spawned two continents.
