LONDON—A year after the tragic explosion and oil spill that caused petroleum giant BP to cease operations in the Gulf of Mexico, the company announced Wednesday that it was once again ready to begin oil spilling. "People said this company might never rebound from last year, but we're here and ready to do what we do best," said BP chief executive Robert Dudley, who confirmed that the company had already successfully conducted small test spills and that full-scale spilling operations could resume as early as July. "We've reorganized and regrouped, and now we're ready to put the faulty blowout preventers on the wellheads and watch them pump raw crude petroleum right into the environment." BP stock jumped $14 a share following the announcement.
