You don't need to read the first two articles in full as they are only leading up to the cover-up and in the 3rd article there is a video. I am putting them in this order as this is how I found them. Flat denial came later and then the video??????? Notice Matt Simmons name mentioned, hmmmmmmmm

Was a massive Saudi Aramco oil spill concealed from the public in 1993
2 EXCERPTs:

1) On one hand, Saudi Aramco has allowed the documentation of many field-related problems in Society of Professional Engineers (SPE) publications. Indeed, Matt Simmons wrote Twilight in the Desert based on an analysis of many such papers. But there is also a curious, almost amateur, approach to the censuring of the papers of name and place data. Nevertheless, information eventually leaks out in some form. A concealment of this magnitude would seem to require a more foolproof approach and motivation.
2)
Alternately, all or part of the story could be fiction. Indeed, after several weeks, Saudi Aramco finally issued a flat denial.

Flat denial
EXCERPT:
Aramco refutes 'secret' spill talk
Oil giant Saudi Aramco today denied allegations reported in several news and media internet blogs about a ‘secret’ oil spill in the Arabian Gulf during 1993.

Saudi Aramco Oil Spill
EXCERPT:
Déjà vu, Oil Over Again

In Esquire Magazine's The Politics Blog, former Shell Oil President John Hofmeister was being interviewed by writer Mark Warren about BP's response to the current crisis when he said this:

JH: The work going on to close the well is taking multiple approaches, and I am aware that BP has sent out a message to all the oil companies asking for help and advice. And I actually sent some people to BP in terms of the spill response cleanup to try to get them aware of a process that has been used in the Arabian Gulf that has not been used in the Gulf of Mexico, and that is to use supertankers, empty supertankers, to suck up the oil off the surface, where they can store the oil, they can treat the water, they can discharge the water and then they can either salvage the oil or destroy it, as the case may be. And I know the mayor of New Orleans and a few other officials are now asking BP about that process as a result of these engineers coming forward from Saudi Aramco.

ES: When did that spill happen, John?

JH: I don't actually know, but it was sometime back, there was a huge, huge spill that never got reported, because they don't have an open press, obviously... But I was told it was a 700-million-gallon spill.

ESQ: That would be the biggest, right?

JH: That would be the biggest the world has ever known. And they used six supertankers to clean up the oil and were very successful. We'd do well to get supertankers in the Gulf.
