Energy Sector Primer

Hi everyone,

I recently searched previous threads regarding a primer for oil & gas companies, but was not able to find anything other than a few posts from 2013, where members sent primers through PMs. I have done some preliminary reading and understand basic concepts (NAV for E&P is popular, PV 10 as the discount rate, etc...), but want to more thoroughly understand and eventually build models for some companies I am interested in.

Does anyone have a primer or reading recommendation for someone looking to learn how to model for oil & gas companies?
