Have you figured out what "reserves" actually means? Have you learned to to actually research something instead of stopping when you read what you want to hear? More reserves doesn't mean more oil has been created. If you thought you have $1.25 in change in your pocket, and upon looking closer, discover that you actually have $1.37, did the extra coin just spontaneously appear?
The White Tiger Oilfield in Vietnam contains oil deposits in FRACTURED granitic rock. This is surrounded and overlain by sedimentary lacustrine shale.
The oil from this field has been analyzed and found to originate from lacustrine sediments; algae and plants.
Probably migrated laterally into the fractured igneous rock.
"there are hydrocarbons on other planets, even in deep space. Why shouldn’t we expect to find primordial hydrocarbons on Earth?
This is a question whose answer is only partly understood, and it is a complicated one. The planets known to have primordial hydrocarbons (mostly in the form of methane, the simplest hydrocarbon) lie in the further reaches of the solar system; there is little evidence of primordial hydrocarbons on the rocky inner planets (Mercury, Venus, Earth, and Mars). On the latter, possibly the hydrocarbons either volatized and escaped into space early in the history of the solar system, or—as Gold theorizes—they migrated to the inner depths. (Note: very recent evidence of methane in the atmosphere of Mars is being viewed as evidence of biological activity, probably in the distant past. (1)) There is indeed evidence for deep methane on Earth: it vents from the mid-oceanic ridges, presumably arising from the mantle, though the amount vented is relatively small—less than the amount emitted annually in cow farts (incidentally, there are persuasive biotic explanations for the origin of this vented methane).
A new study by the US Department of Energy and Lawrence Livermore Lab suggests that there may be huge methane deposits in Earth’s mantle, 60 to 120 miles deep. (2) But today oil companies are capable of drilling only as deep as six miles, and this in sedimentary rock; in igneous and metamorphic rock, drill bits have so far penetrated only two miles. (3) In any attempt to drill to a depth remotely approaching the mantle, well casings would be thoroughly crushed and melted by the pressures and temperatures encountered along the way. Moreover, the DOE study attributes the methane deposits it hypothesizes to an origin different from the one Gold described.
More to the point, Gold also claimed the existence of liquid hydrocarbons—oil—at great depths. But there is a problem with this: the temperatures at depths below about 15,000 feet are high enough (above 275 degrees F) to break hydrocarbon bonds. What remains after these molecular bonds are severed is methane, whose molecule contains only a single carbon atom. For petroleum geologists this is not just a matter of theory, but of repeated and sometimes costly experience: they speak of an oil “window” that exists from roughly 7,500 feet to 15,000 feet, within which temperatures are appropriate for oil formation; look far outside the window, and you will most likely come up with a dry hole or, at best, natural gas only. The rare exceptions serve to prove the rule: they are invariably associated with strata that are rapidly (in geological terms) migrating upward or downward. (4)
The conventional theory of petroleum formation connects oil with the process of sedimentation. And, indeed, nearly all of the oil that has been discovered over the past century-and-a-half is associated with sedimentary rocks. On the other hand, it isn’t difficult to find rocks that once existed at great depths where, according the theories of Gold and the Russians, conditions should have been perfect for abiotic oil formation or the accumulation of primordial petroleum—but such rocks typically contain no traces of hydrocarbons. In the very rare instances where small amounts of hydrocarbons are seen in igneous or metamorphic rocks, the latter are invariably found near hydrocarbon-bearing sedimentary rocks, and the hydrocarbons in both types of rock contain identical biomarkers (more on that subject below); the simplest explanation in those cases is that the hydrocarbons migrated from the sedimentary rocks to the igneous-metamorphic rocks."
