Where can i read up on Oil?

Due to the current geopolitical issues, Oil is in the news alot lately.

But oil has always been a confusing topic to me. I dont understand its economical correlation. as well as its financial correlation.

in addition, theres alot of companies that are under the tag “oil” but they are all different.

i was wondering where can i go to get a better understanding of all this?

for example

1. “Oil price is going up”. where do i go to see its value?

2. various company stocks are going up, yet some other oil companys are stagnant. i.e. BP, and WTI.

3. what are the differences between all these companies?

etc etc.

in addition, theres so many acronyms
