[Old School]

You never did show us where a natural secretions, world wide, equaled 500k gallons a day SD. You seem to gotten very quite on this thread.

While surfing through the net I ran across these articles on the Deep Horzion well that has been capped after more than a 100 days, and nearly 210 million gallions of oil leaked into the Gulf.

Approximately 75% of the leaked oil has now disapeared, either by mother nature, pumps, burned off or broken down by dispersants.

According to a Nationnal Academy of Science report 180 million gallons of crude oil naturally seep from the sea floor into the Oceans each year.

Natural Oil Seeps


Oil seeps are underwater cracks in the Earth’s crust that release naked crude oil into the sea. As the graph below illustrates, offshore production accounts for the smallest fraction of petroleum that is leaked into North American waters.

• Natural seepage of crude oil from geologic formations below the seafloor is estimated to exceed 47,000,000 gallons in North American waters and 180,000,000 gallons globally every year. [3]
  

• Natural oil seeps are responsible for over 60 percent of the petroleum entering North American waters, and over 45 percent of the petroleum entering the marine environment worldwide. [3]
  
  

• Petroleum contamination from oil seeps in North American waters is about 60 times greater than the amount released through oil exploration and production.
