@hawkeye10,
The "curvelinear" area between Cuba and Aruba is , possibly an untapped deep source of petroleum and gas. Its an area that been squozen during the collision of Sa and Central America.
Lots of possible oil basins. Theyre pretty much done screwing around off Cuba and I think that the fields to the N (the deept fields) and to the South (shallower AND deep fields can be exploited further
