RIGHT ON. OLDSALT and DIRE! The concept you describe also has been referred to as the "modern Russian-Ukrainian theory of deep, abiotic petroleum origins." A web site known as www.gasresources.net provided a great deal of information on this subject. The site is being updated, as explained here, but still includes numerous clickable references:

OldSalt, is this where you got the article you linked to?

The late Thomas Gold, an American petroleum geologist wrote extensively on this subject, beginning in the late 1980s
https://muse.jhu.edu/article/26015
"Gold has been writing on this subject for the last 20 years in both technical and popular articles and in a book called Power from the Earth, Deep Earth Gas -- Energy for the Future, published by Dent in 1987. To judge from books on petroleum geology and geochemistry published in the same period, the effect of his ideas has been insignificant. But Gold is a very clever physicist, and what he writes, whether it turns out to be right or wrong, is worthy of careful attention. The book under review is his latest and most ambitious statement of his theory, and is directed to a general readership, with occasional impatience expressed at the lack of interest by petroleum geologists. It is thus an example of going over the heads of the experts to appeal to an intelligent public, something that, to name one prominent scientist, Galileo did with considerable effect."

Jerome ( book a month) Corsey, who will write on anything that sells, has belatedly identified the deep oil theory in one of his books, the name of which escapes me, but never mind, he is a sensationalist junk writer and offers no new information on deep oil..
