AP-Cuba doing their job. Look at this:
Experts say it is not unusual that a 3-mile (4.8-kilometer) deep exploratory well drilled at a cost of more than $100 million by Spanish oil giant Repsol was a bust. Four out of five such wells find nothing in the high-stakes oil game, and petroleum companies are built to handle the losses.
But Cuba has more at stake, and only a few more spins left of the roulette wheel. The enormous Scarabeo-9 platform being used in the hunt is the only one in the world that can drill in Cuban waters without incurring sanctions under the U.S. economic embargo, and it is under contract for only one to four more exploratory wells before it heads off to Brazil.
