If anything, a modern biological source would be more likely to support oil field replenishment. I suspect the "theory" may be a distraction tactic, intended to confuse and delay people who might otherwise spend time annoying oil companies.

There's a gene-tweaked breed of E. coli that produces diesel oil as a waste product, so it's not biologically impossible.

Some of the gas coming from shales is actually biogenic. The Marcellus (I think it is) shale in Michigan, for example, has a part where the methane is produced by microbes acting on kerogen in the shale.

Excessive salinity shuts this off, so one solution is to purge a fracked shale formation with fresher water.

I worry a bit that once gas shales are "done", the fracturing will lead to long term production of more methane, which may leak out for centuries.
