More than 3,200 oil and gas wells classified as active lie abandoned beneath the Gulf of Mexico, with no cement plugging to help prevent leaks that could threaten the same waters fouled by last year's BP spill, The Associated Press has learned. These wells likely pose an even greater environmental threat than the 27,000 wells in the Gulf that have been plugged and classified officially as "permanently abandoned" or "temporarily abandoned." Those sealed wells were first tallied and reported as a major leaking threat in an investigative report by the AP in July. The unplugged wells haven't been used for at least five years, and there are no plans to restore production on them, according to the federal government. Operators have not been required to plug the wells because their leases have not expired.
As a result, there is little to prevent powerful leaks from pushing to the surface. Even depleted wells can repressurize from work on nearby wells or shifts in oil or gas layers beneath the surface, petroleum engineers say. But no one is watching to make sure that doesn't happen.

Thank you...
think about it..
3,200 well still out there that are still, to this day..
uncapped and spewing oil and other crap into the gulf..
no one on here cares lately..
The oil and gas industry generally views plugging on unexpired leases as an inconvenience and prefers the freedom to resume operations at any time on such wells. When BP's Deepwater Horizon well blew in the Gulf last April 20, it was being temporarily abandoned to await later production. A poor cement plugging job has been identified as a chief cause of the deadly explosion and spill. Engineers say the metal and cement lining inside abandoned wells, as well as the plugs, can break down over time and allow leaking. Petroleum or corrosive brine, which is even saltier than sea water, can leak from under the sea floor, harming aquatic life.
