Santos Basin: 40 Years from Shallow to Deep Waters
From 1970 to 1987, 57 dry holes were drilled in the Santos Basin, with only one small gas field in Santonian turbidites being discovered. Exploration was based on low-resolution 2D seismic grids, the petroleum system was poorly understood, and drilling was limited to 200 m water depths. In 1988, a small oil province was found in Albian grainstones, but the low success rate persisted for ten years more. By the turn of the century, the exploratory activity benefited from much better 3D seismic, and deeper water semi-submersible rigs were available. Some medium-sized oil & gas fields were thus discovered in Santonian turbidites, in water depths ranging from 200 to 1500 m. But the big oil was still waiting for the daring decision to drill through 2000 m of salt, in 2000 m deep waters, aiming Aptian microbial carbonates, in what proved to be a completely new kind of petroleum system. Oil and gas reserves in those carbonates are yet to be evaluated, but they are likely to climb to tens of billions of barrels. Santos Basin is a very good example of how much oil is kept in remote and difficult sites, just waiting to be found by bold explorationists with proper means and resources.
