I'm not gonna stay, but thought some of you would find value in this:

The earliest known oil wells were drilled in China in 347 CE. These wells had depths of up to about 240 metres (790 ft) and were drilled using bits attached to bamboo poles.[1] The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as Burning water in Japan in the 7th century.[2]


Found it while doing some quick fact checking for my new novel draft.

Thanks for posting. That is interesting, wikipedia says this about petroleum:

Petroleum is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.


Do you think they had fractionating columns in ancient China?

They didnt need them. Fractional distillation is used to create a series of different fuels, however, a standard distillation of crude oil will yeild a crude petroleum in the reciever and deisel in the boiling flask.

I think the fractional distillation is to extract things like naphtha ect.
