Question

which are three requirements for forming petroleum? oxygen, heat, steam heat, time, pressure time, oxygen, pressure pressure, steam, time

Petroleum forms when organic matter is buried, subjected to long-term heat, pressure, and time in an oxygen-poor environment. Oxygen would break down the organic material instead of allowing petroleum formation, and steam is not a core requirement for its natural formation.
