Exxon oil still on the beaches

Oil from the 1989 Exxon Valdez spill was expected to be completely gone by now, according to the original calculations. However, about 20000 barrels of oil remain in the environment. At the current price of oil $78 (so about 1.5 million US) I wonder how much of the oil would need to be recovered to make it profitable. Obviously it wasn't feasible at the time, but oil recovery methods and technology has come a long way in twenty years. Maybe some enterprising company 9or student group) could get a grant or two to use this area as a real world testing environment.
