A study of ancient stromatolites reveals that ammonium reservoirs in early Earth's oceans, likely influenced by volcanic activity, may have supported microbial life before the Great Oxidation Event.

By analyzing these fossilized formations, the researchers aimed to understand how nitrogen cycles operated in early Earth's ...

Therefore, nitrogen is more commonly produced onsite ... A negative for this approach is that in most reservoirs the pressure in the wellbore cannot be reduced enough to achieve underbalance.
