The conventional method of relief wells will succeed. If highly unusual circumstances arise, and the two relief wells must be abandoned, BP will keep drilling more wells until the oil well is capped. Sometimes there is stuck drill pipe in the well, and then the well may be sidetracked to continue drilling. Some wells after flowing for long periods of time, "bridge over" meaning that rocks and sand entering the wellbore eventually form a plug.
If oil spills keep occuring than over time the world will be in a BIG problem because it will kill more animals and hurt your human health and might end the widlife.
