Question

Quizplus · Accepted Answer

After the generation of hydrocarbons in a sedimentary basin, microbes will digest the smaller hydrocarbon molecules, leaving behind the larger, more viscous oil compounds. This process is known as biodegradation and is a common occurrence in mature oil fields where microbial activity has had time to take effect. The result is that the remaining oil is more difficult to extract and often requires enhanced oil recovery techniques.
