The math of how quick oil is made:

1) 50 atmospheres. 1 atmosphere is 14.7 psi.
2) Between 400-500 degrees F.
3) Bio-mass. Plants or dead animals.

Has this been tested?

A company named Changing World Technologies is already applying this process and is producing bio-diesel.

Currently they use chicken parts (what is normally thrown away), which means that waste is turned into energy. And provides another way for farmers to make money.

When is the process to start?

It has already started. http://www.changingworldtech.com/when/index.asp

How would this conditions be produced naturally to make quick oil?

In order for the earth to be flooded to it's highest point. In the least there had to be 14 miles of water. This is a measure from the bottom of the ocean to the highest mountain.

Math of the water needed for flood:

The Radius of the Earth = 3963 miles
The Radius of the earth with 5 miles of water = 3968 Miles.
The volume of the earth = 260711882973.3396 cubic miles
The volume of the earth with water = 261699925947.5533 cubic miles.
261699925947.5533 - 260711882973.3396 = 988042974.2136999965
So the volume of the flood water = 988,042,974.2136999965 cubic miles. But lets round it to 988,042,974 Cubic Miles.
If this water was put into a sphere, it would have a radius of 618 Miles.

This much water would produce very high pressures. The math of this is:

1) Every 33 feet equals one atmosphere (13-14 miles of water). There are 5,280 feet in a mile.
2) One atmosphere is 14.7 psi.
3) Heat source is upper mantle of the earth's crust.
4) Heat needed is 400-500 degrees F.

Current conditions:

1) Crude oil found today averages in heat at around 400 degrees F.
2) Crude oil found today has pressures between 5000-20,000 plus psi

Where did the water come from for the flood to make such pressures?

There has been testing and research done on the upper mantle of the earth. A mineral called wadsleyite, holds about 3% water by weight. And the estimated amount of wadsleyite that exists, the water contained in it works out to be about 30 of our oceans. 30 oceans worth of water is more than enough to flood the earth to the highest mountain.
