In the early days of the Deepwater Horizon disaster, I was puzzled by an observation that received little attention at the time. When a few tar balls were found on the Florida coast, an official said that these were probably not from the Deepwater well and would have to be tested to determine origin. At the time I thought, “How odd; if not from Deepwater, where else would tar balls be coming from?” Today I found a possible answer in THIS ARTICLE.
There are now more than 27,000 abandoned oil and gas wells JUST IN THE GULF! This has been on going since the 1940s with little if any regulation and virtually no oversight or monitoring of the well heads. One can only imagine what might be happening to concrete that has been exposed to sea water and ocean floor disturbances.
If a well is only temporarily abandoned, the requirements for sealing them are less stringent. The company with drilling rights is supposed to either reopen the well or close it off permanently within a year but this rarely happens. I suspect that many wells are “temporarily” closed simply to save money with no intentions of reopening them.
Capped wells on land and under water can repressurize and those capped on land frequently leak. Not much is known about how many wells are now leaking in the Gulf because no one is monitoring them.
The US Mineral Management Service, now the Bureau of Ocean Energy Management, Regulation and Enforcement, which is supposed to oversee the operation and condition of these wells has done little more over the decades than shuffle paper.
“In the end, the Coast Guard's Marine Safety Laboratory handles little more than 200 cases of oil pollution each year. And manager Wayne Gronlund says it's often impossible to tell leaking wells from natural seeps, where untold thousands of barrels of oil and untold millions of cubic feet of gas escape annually through cracks that permeate the sea floor.”
The Deepwater Horizon leak is just the tip of the iceberg. The Gulf could easily become our Chernobyl.
