RE: Are Hydrocarbons Renewable?The earth is not equivalent to Saturn's moon Titan where methane has been produced inorganically. Fact is most of our oil and gas production is 'biotic/biogenic', reservoirs in contact with petroleum generation systems that are organic in origin.
"Attempts of drilling abiogenic HC
Drilling for abiogenic gas by the astronomist Thomas Gold in the Siljan
crater in 1988 and 1991 has been failure, as methane was not found and
the rumored 80 b of recovered oil in granite is assumed to come from the
drilling mud. In Saskatchwan, in 1991 Warren Hunt has leased 9600 km2 on
Precambrian bedrock aiming to abiogenic HC in the Craswell crater (35 km
diameter and 478 Ma old). No drilling (as far as I know) has been carried
out ; as I presume that Hunt has not found anyone to invest in his ideas
after the failures in Sweden.
No one major oil and gas companies explores for abiogenic HC.
The IFP (Institute Francais du Petrole) school discards the abiogenic
theory, as there is no proof of it.
Conclusions :
The proposed proofs of evidence of abiogenic origin in the Dnieper-Donets
basin and in refilling fields are dismissed in front of real data."
I'll put my money into the biogenic theory.
