Did anyone else notice this little land mine embedded in the article?
What's the problem?
Abiotically means "without life". Are you trying to claim that gas and oil can only be produced from biological material?
I think it's pretty settled that gas and oil can be produced by purely geological and chemical means.
Oh no! I agree with you.
I think that most petroleum engineers would agree that oil deposits come from sedimentary remains of living organisms. This is probably true for most natural gas. However, natural gas appears to also be made (for example, in Jupiter's moons) from an abiotic process. Therefore, we should be open to the possibility of discovering natural gas here on the earth that is of an abiotic origin.
Why then is it only found incorporated in sediments? There are some types of metamorphic and igneous rocks porous enough for this, yet it´s not observed.
