You mean possible producer of abiotic oil. Well technically no, because these are organisms, so it would be oil of biologic origin. (I believe abiotic means not biological origin!). These organisms (I assume are similar to thermophiles*.) fit the late Dr Thomas Gold’s claims in his book “”The Hot Deep Biosphere”. It’s worth a read!
* thermophiles - bacteria, etc that inhabit deep ocean volcanic vents. Live under high temperature, high pressure, high metallic conditions.
Thanks for the ‘word’!................
