What for? It's a myth based on wrong geology theory. we should be reducing its credibility, not improving it.

— Sir Fred Hoyle, 1982“The suggestion that petroleum might have arisen from some transformation of squashed fish or biological detritus is surely the silliest notion to have been entertained by substantial numbers of persons over an extended period of time.”
The trouble with the theory? So far, abiotic oil has not been proven to exist on Earth in any economic quantities. Oil exploration geologists have also not been able to make any discoveries using abiotic theories, and many abiotic claims have been debunked as pseudoscience.
Kenney et al. (2002) analyzed theoretically, via thermodynamic computations, the possibilities for hydrocarbon generation at high pressures and temperatures and showed that it is possible. They went on and performed successful experiments, using a specially built high pressure apparatus (Nikolaev and Shalimov, 1999) at pressures of 50 kbar, temperatures to 1500 °C . Using only as reagents solid iron oxide and 99.9% pure marble, wet with triple distilled water, they were able to generate methane. They reported that at pressures lower than 10 kbar only methane was formed while at pressures greater than 30 kbar a multi-component hydrocarbon mixture was formed including methane, ethane, propane, n-alkanes as well as alkenes, in distributions characteristic of natural petroleum.
Meanwhile, however, the oil companies have used the biotic theory as the practical basis for their successful exploration efforts over the past few decades. If there are in fact vast untapped deep pools of hydrocarbons refilling the reservoirs that oil producers drill into, it appears to make little difference to actual production, as tens of thousands of oil and gas fields around the world are observed to deplete, and refilling (which is indeed very rarely observed) is not occurring at a commercially significant scale or rate except in one minor and controversial instance discussed below.

Yep. That's for 2 reasons
1. The current average depth of US wells is well above the depth where oil forms.
