Howcome they discover oil at 30K feet?

Unread postby misterno » Sun 20 Jun 2010, 10:26:15

FACTS ARE FACTS

Oil being discovered at 30,000 feet, far below the 18,000 feet where organic matter is no longer found.

(wells as far as 40000 feet have hit oil )


Wells pumped dry later replenished.

Kantrowitz turned to the geologist beside him and asked, "Do you really believe that petroleum is a fossil fuel?" The man said,"Certainly" and all four of them joined in. Kantrowitz listened quietly and then said, "The deepest fossil ever found has been at about 16,000 feet below sea level; yet we are getting oil from wells drilled to 30,000 and more. How could fossil fuel get down there? If it was once living matter, it had to be on the surface. If it did turn into petroleum, at or near the surface,how could it ever get to such depths? What is heavier Oil or Water?" Water: so it would go down, not oil. Oil would be on top, if it were "organic" and "lighter."

"Oil is neither."

They all agreed water was heavier, and therefore if there was some crack or other open area for this "Organic matter" to go deep into the magma of Earth, water would have to go first and oil would be left nearer the surface. This is reasonable. Even if we do agree that "magma" is a "crude mixture of minerals or organic matters, in a thin pasty state" this does not make it petroleum, and if it were petroleum it would have stayed near the surface as heavier items, i.e. water seeped below.

hey peekers, could you please provide scientific evidence how the above events could happen under a oil exclusively as a fossil fuel
theory

the masses believe the fossil fuel theory because that is what has been thought for many years and it's so engraved in their head that this is true. even though they can't explain the above

I suspect that the earth is round theory came against similar disbelieving

I read a real scientific paper where they drilled into truly ancient rock below a gas dome I think and looked for any traces of, well, anything. Despite being in an area with producing wells, once they went deeper there was nothing. Everything dropped to zero except for some traces of gas like hydrogen that you'd find in outer space. They thought they might find some contamination from higher levels, but found nothing.

Where a river flows into the sea, mud containing organic material gets deposited at great depths. They are drilling into these deposits, now fossilized.

Geologists see fossils in the drill chips.

"It" doesn't turn to petroleum on the surface, heat and pressure changed organic matter laid in the Carboniferous period into fossil fuels. The conditions need to be just right, hence no oil in your tap water. Here is a simple page.

Hopefully one of our petroleum geologists will grace us with in depth knowledge bent for the lay person.

As we all know organic matter that is allowed to decay breaks down into soil and doesn't make coal and oil and gas. It takes the organic material being trapped where it can't oxidize (where a large river system dumps material into the sea for example) and then being buried under sediment and rock until the heat and pressure convert it to oil typically between 2-4 kilometers deep or gas (3-6 kilometers deep) in what is called the "kitchen", the combination of heat and pressure over time required to do the transformation process. The results of what are produced in this "kitchen" percolated up until they either escape and are lost as seeps or vents or become trapped under something impermeable and await the drillers craft to produce them as oil or gas (often both).

Sedimentary rock is too thin or absent over much of the deep ocean floor and large swaths of the land masses as well to have the hierarchy of hydrocarbons such as lignite, coal, oil, and gas (according to pressure and temperature) form and have a portion of formation be trapped that can be exploited. Sedimentary rock can be really deep, 85,000 feet in the Caspian basin and 40,000 feet in a few of the other deep basins, where temperature and pressure can exist to simply cook the organic material to where oil and gas transform beyond petroleum and gas and I assume form other compounds instead (geologist help us here).

Having said all of that in addition to layers of sedimentary materials typically assumed to define the depth of the oil and gas "kitchen" there can exist huge salt layers that act as a heat conduit between the deep layers and the shallow ones and allow the depth of the "kitchen" to extend down from the rule of thumb values that are easily taught in books and layman's presentations. I imagine other factors that mitigate heat, time, and pressure (the recipe needed in the kitchen) can alter the recipe for better or worse and affect the standard depths that usually are cited for coal, petroleum, and gas.

From where oil and gas are cooked in the kitchen to where they percolate higher to a trap that is drilled as a reservoir can provide for scenarios where organic materials converted deeper are replenishing reservoirs located higher up. Just to let you know, there is another theory that deep earth processes also make significant quantities of liquid and gaseous hydrocarbons that become trapped in similar formations as the organic types, but in practice, virtually all of the successfully exploited deposits and the associated funds risked to retrieve them, fall in line with what is presented here. (wiki abiotic oil to bone up on this debated topic)


So far as drilling really deep and finding traces of only hydrogen: the "kitchen" process is converting enormous bulks of organic materials into solids, then liquids, and finally gas depending on pressure, time, and heat applied in the "kitchen". So far as relative gravity (oil below water etc.) it has to be remembered that the feedstock is a solid material and heavier than water until such time as it is converted to lighter compounds in the geologic process window. Remember, in my example it was organic sediment that settled from a river delta to the bottom of a sea. This whole exercise is about getting hydrogen to burn in solid, liquid, or gaseous states to suit the combustion device at point of consumption. Gasoline is a hydrogen fuel source of extreme utility and convenience.

Petroleum geologists please give us better than this when you can.

And that is my J6P , er J3B, crack at it Pops. (J6P is Joe Six Pack, J3B is Joe Three Beers)
If the geologist tell me to get the hell out of their kitchen, I have spousal training in that regard and have the means and experience to comply after I make sure I have loaded my pockets with a tasty morsel or two to prove that I have game as well as manners.

So people that buy gold coins at 1000% markup can also waste their money on abiotic mining companies.

Also, since this is pitched to Young Earth Creationists, it can be peddled to church members, and churches are always the best place to suck people into financial scams.

Pops is right.. you have to remember that the Earth's surface hasn't always looked the way it is now. The plates are constantly in motion, forming, eroding, and reforming continents and mountain ranges and oceans and everything else over and over again.

This is a very geologically active planet we live on.. you can't just stand in one spot in 2010 and say "well how could animals have ever lived here" since that same spot has seen many varied climates and elevations over the billions of years.

oil generation from source rocks is mainly about time and temperature but also pressure comes into the equation. The oil window (the zone at which oil forms from source rock) is quite deep and thick in the Gulf of Mexico. The Macondo well has its source rock sitting somewhere around 13,000 feet below mud line and temperatures here are in the 200 F range. What is important in Tertiary reservoirs such as this which are young and deposited rapidly is the presence of over-pressuring. Over pressures tend to inhibit the formation of oil from source rocks which means that in an over pressured situation oil can be generated at depths greater than one might normally expect. This has been demonstrated in the lab and is backed up by an enormous amount of real data from offshore wells.

I was curious about the temperature of the rock. A lot of deep boreholes are way way hotter than that, as oil is often found in geothermal areas in the western US and pacific rim.

The Mississippi Delta has a much lower heat flow then the tectonically active cratonic areas of the western US. As a result, the "golden window" where the temperature falls in the right range to allow oil to form lies at a much greater depth.
