I want to know the answer to the following question:
When did the modern petroleum industry start?
All the background I'm provided with is that "Ignacy Łukasiewicz improved Gesner's method to develop a means of refining kerosene from the more readily available "rock oil" ("petr-oleum") seeps in 1852 and the first rock oil mine was built in Bóbrka, near Krosno in Galicia in the following year.". Is that enough to answer the question?
