The Tiber Oil Field is a deepwater offshore oil field located in the Keathley Canyon block 102 of the United States sector of the Gulf of Mexico. The deepwater field (defined as water depth 1,300 to 5,000 feet (400 to 1,520 m),[2]) was discovered in September 2009 and it is operated by BP. Described as a "giant" find, it is estimated to contain 4 to 6 billion barrels (640×106 to 950×106 m3) of oil in place.[3][4] Although BP states it is too early to be sure of the size – a "huge" field is usually considered to contain 250 million barrels (40×106 m3).[3] It required the drilling of a 10,685 m (35,056 ft) deep well under 1,260 m (4,130 ft) of water, making it one of the deepest wells ever drilled at the time of discovery.[5][6][7]

10 kilometers or deeper could be the magic zone in which oil forms. (originates)
Where everything comes together (chemical components, heat, pressure and time) before percolating towards the surface.

Thanks. That was worth some laughs.
If this was supposed to be some kind of indictment of the 8km- 10km rule-of-thumb, it fell short of the goal:
* The only evidence which could support your premise was never disclosed by British Petroleum.
* A 'hint' was provided in the data for BP's 'Kashida' well, of 32,500-foot depth.
* By default, you've given the authors of the rule-of-thumb a classroom grade of 'A.' Any way you do the math, their metric fell within 93%, a discrepancy of only a little over 6%. That's pretty good for a globally-averaged metric.
-------------------------------------------------------------------------------------
* I'm constructing a proper rebuttal, and will report when complete.
* If you want to go 'to trial', I encourage to revisit your textbooks on, Geology, Oil Well Drilling Technology, Petroleum Engineering, Well completion, and Oil Refining Fractionation Distillation Temperatures, Chemical Thermal Dissociation. That's what I've been doing.

And as an aside: this notion about petroleum originating from Earth's mantle is currently under examination in Hawaii.
Kilauea and Mona Loa Volcanoes have been under continuous eruption for some time now.
Since the Hawaiian lava and magma communicates directly with Earth's mantle, if hydrocarbons are sourced from deep within the planet, they should be venting from both volcanoes.
And since they both have an 1,800-degree F ignition source, plus infinite oxygen available for combustion, both locations ought to be enshrouded with firenadoes, continuously.
If mantle-sourced hydrocarbons exist, I can't possibly think of a better location from which to presently experience the phenomenon.
I'll be back when I've completed my studies.
