ScienceDaily (Jan. 27, 2000) — Twice an Exxon Valdez spill worth of oil seeps into the Gulf of Mexico every year, according to a new study that will be presented January 27 at the Ocean Sciences Meeting in San Antonio, Texas.
But the oil isn't destroying habitats or wiping out ocean life. The ooze is a natural phenomena that's been going on for many thousands of years, according to Roger Mitchell, Vice President of Program Development at the Earth Satellite Corporation (EarthSat) in Rockville Md. "The wildlife have adapted and evolved and have no problem dealing with the oil," he said. www.sciencedaily.com...

Radarsat image of oil seeps near Green canyon in the Gulf of Mexico. The oil reaching the sea surface produces a slick that reflects little radio energy, seen as black lines in this image. Radarsat is a Canadian satellite that uses a synthetic-aperture radar to map radio waves reflected from the sea surface.
The major sources of petroleum in the sea, in order of importance, include:
1. Natural seeps from rocks below the sea floor. Oil seeps are common in many areas, including the Gulf of Mexico and offshore of Southern California, and in other areas where oil is found beneath the continental shelf.
2. Consumption, which includes runoff from land and oil from marine boating and jet skis in coastal waters. Most cars drip oil on streets and highways which is washed off by rains. The millions of cars in large coastal cities are important sources.
3. Transportation, which includes spills from tankers and pipelines as well as intentional discharge from ships at sea.
4. Extraction, which includes spills from offshore platforms and blowouts during efforts to explore for and produce oil and gas. An example is the IXTOC I oil well blowout in the Bay of Campeche, Mexico, June 1979 to March 1980, which released 476,000 tonnes of crude oil into the Gulf of Mexico.
Oil Spills
Oil spills from oil tankers operating at sea world-wide account for only 7.7% of oil in the ocean, yet large spills attract far more attention than other much larger sources of oil pollution. The International Tanker Owners Pollution Federation Historical Data has information on all spills, large and small. They note that "The average number of large spills per year during the 1990s was about a third of that witnessed during the 1970s."
Spill conditions: It is estimated that more than 500,000 tons of crude oil was spilled into the Gulf of Mexico from blowout of the Ixtoc I well offshore in the Bay of Campeche. It occurred in early 1979, and several months later impacted the Texas shoreline, primarily along Padre Island. An early storm in September, reversed the currents and self-cleansed most of the shoreline, leaving only (relatively unusual) tarmats. LINK
According to a study sponsored by UNESCO, Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates and the United States, the spill did little long-term damage. About half the oil evaporated, a million barrels were recovered and 2 million to 3 million barrels washed ashore, mainly in Saudi Arabia.[2]

On July 19, 1979, during a tropical rainstorm, the ship collided with the Aegean Captain, off Trinidad and Tobago, spilling 287,000 metric tonnes of oil consigned to Mobil. The damage incurred from the collision was never completely remedied, and while being towed on August 2, the Atlantic Empress continued to spill an additional 41 million gallons (all together being 276,000 tonnes of crude oil) off Barbados. The Aegean Captain also spilled a large quantity of oil from her No. 1 tank. The Atlantic Empress sank on 3 August in deep water and her remaining cargo solidified. The spill from the two ships fortunately never came ashore.
By comparison, the infamous Exxon Valdez spill ten years later only saw 37,000 metric tonnes of oil released. en.wikipedia.org...

Currently, the number of US structures in the Gulf is roughly 4,000, with 819 manned platforms. And those numbers are only expected to grow, says Caryl Fagot, a spokeswoman for the federal Minerals Management Service (MMS), which regulates the oil industry in federal waters.

Waay back in the 1960s, I remember wandering along the beach at Galveston, collecting shells and shark teeth, and often stepping into globs of sticky tar, which would stain my skin brown for days afterwards. When we went swimming in the surf, we'd come back with brown globs on our skin and swim trunks — and that stuff did not wash out of fabric. www.abovetopsecret.com...
Induced seismicity in oil and gas production has been observed ever since the 1930s, i.e., ever since large scale extraction of fluids occurred. The most famous early instance was in Wilmington, California, where the oil production triggered a series of damaging earthquakes
In this instance the cause of the seismicity was traced to subsidence due to rapid extraction of oil without replacement of fluids. Once this was realized the oil extraction was balanced with water injection to mitigate the seismicity

Earth, in my opinion would be better off minus one species, homosapien.
Every year 100 million US gallons of oil spill. This is equal to 100 school gymnasiums.
The biggest spill ever occurred during the 1991 Persian Gulf war when about 240 million gallons spilled from oil terminals and tankers off the coast of Saudi Arabia.
The second biggest spill occurred over a ten-month period (June 1979 - February 1980) when 140 million gallons spilled at the Ixtoc I well blowout in the Gulf of Mexico near Ciudad del Carmen, Mexico
The Exxon Valdez spill in Alaska was approximately 11 million gallons. That spill was only about the 35th largest in the world

DAUPHIN ISLAND, Ala., May 14 (Reuters) - The oil slick from the huge uncontrolled spill in the Gulf of Mexico has broken into smaller parts, and while potentially catastrophic, may pose less threat of a massive landfall, U.S. Coast Guard Commandant Admiral Thad Allen said on Friday.
"The character of the slick has changed somewhat, it is disaggregated into smaller patches of oil," said Allen, who is leading the response to contain what could be the worst oil spill in U.S. history.
"It's not a monolithic spill, we're dealing with oil where it's at," Allen added.
Thin surface oil "sheen" and globs and balls of tar from the spill so far mostly have affected outlying parts of the Louisiana coastline. Tar balls also have washed ashore on Alabama's Dauphin Island.

How much oil would it take to "wipe out" any given percentage of the Gulf? I dont know, but I can tell you that its about 642 trillion gallons. That should give us a starting point.
