The idea that the massive amounts of oil already extracted and that remain in the earth are all simply dead dinosaurs and pre-historic plants is laughable.
—there are no doubt many details of which we are unaware, of processes below about 25000 feet in the crust of the earth-—
Sulfur comes from evaporites deposited in and around the reservoir. The most common is anhydrite, which is CaSO4. Salt, also known as halite (NaCl) is another. They were deposited in hypersaline waters, such as the Dead Sea of today. Yes, there have been fields that have “burped” up some more oil but it probably leaking up the faults that are the trap for the field. Once the pressure is drawn down from production, you can get mini-earthquakes as the faults compensate for the pressure differential.
I can’t say that I know for sure, but generally speaking, due to the cost of exploration, you want to search in the highest probability areas.
Very little unless it is fractured. Mostly in the Texas Panhandle and Australia but they have conventional reservoirs overlying the tombstone.
Oil is not usually found below 10,000’ except in “cool” basins, such as the Gulf of Mexico. At higher temperatures, the Earth acts like a refinery and cooks the oil into more volatile members, like methane, butane, etc... Very little natural gas has been found below 20,000’ (except in these “cool” basins) because the overburden of the Earth crushed the porosity so that there is no place for the gas to reside.
What about the recent discovery of oil off Florida by BP? Here is the article: http://www.dailymail.co.uk/news/worldnews/article-1210691/BP-strikes-giant-oil-Gulf-Mexico.html
According to the article, they must have drilled 30,000feet through the crust to get to it. If it is from plants and animals, how did it get that far under the crust, expecially if it is so light to begin with?
--my point was that we really have little detail knowledge of events and processes that deep except that they occur in high temperature, high pressure environments-
Even from what was known to be there before we would never have needed any sand monkey juice, ever!
Excuse my French, but the things who flew down the Towers were from right there , you know.
Speaking of that why don't we just bill them and have them build'um right back up?
Also, if the data is correct, those deep wells tend to fill back up quicker.
Post 12~14 = dead on , - not enough dinos (that wrong idea dates back to a lone Russian scholar in 1757), and sulfur?, oh, yeah, a one two punch there.
So many just accept stupid ideas and don't stop and think for themselves using basic facts.
I’ve had an idea that many concentrated surface ore bodies came from the cores of crashed asteriods. May be totally off-whack here though.
Just try, I dare you?
Now there's a good reason for a space program, n'est pas?
I mean who cares about the moon(unless there oil up there under all that cheese)?
—FYI, you might take a Geology 101 course or get a basic geology textbook and read up on ore deposition-—
Assume sediments form on a seabed at the rate of .01 inches per year. After 1 billion years, you will have total accumulation of 10 million inches which equals 158 miles!
“I work in oil and gas. There is a theory called The Abiotic Theory that says oil is not created from fossils and dinosaurs and stuff, but rather earth processes.
Supporting evidence for this is when a company drains an old field and comes back 10 or 20 years later to suck up any residue, they sometimes find that oil has seeped up into the empty spaces, filling up the previously-empty reservior with oil that is geologically younger than the previously-extracted oil. This is counter intuitive, since oil at a lower level should actually be OLDER than the oil on top of it. Wierd.”
Oil/gas can migrate within/along reservoir layers, from high pressure, to low pressure areas.
Primary recovery doesn’t “drain” a reservoir. It takes perhaps 5 - 15%.
Water, natural gas, air injection, (secondary recovery) augments this process by increasing pressure, and fluid movement/migration.
Seconday recovery may yield total production of up to 50% of the original oil in place.
Tertiary recovery might get another 15%, leaving 35% that is never recovered.
* disclosure - my knowledge is from technology 35 years ago. I worked in secondary recovery and reservoir engineering, with post grad. level engineers and geologists.

...very likly not abiogenic, as far as I've been informed, but "different" oil than was originally produced at that well.
