This has been done.

Take some biomaterial like wood, feed it to bacteria, then compress+heat with some time. The result is a bunch of hydrocarbons that look like some type of crude oil.

We can change the feedstock (trees, leaves, animals), change the bacteria, fungi, etc, change the pressure and temperature, easily manipulate the time.

Mostly, we don't want crude oil. That fingerprint is good at identifying the source, but it's not very useful for the effort we put it. We want to make valuable hydrocarbons. Modern examples of this are anaerobic digestions. For instance, all your household waste that goes to landfill. We can bury that and put an exhaust pipe inside. Eventually, all the microbes in the landfill start to make methane gas + a heavy crude sludge that sinks to the bottom.
