LPG is a off shoot of oil drilling, LNG can also be found with oil sometimes but I guess that is a fairly clean energy overall. The BP oil failure was methane in that oil field, so common that exxon avoided the place as too risky if I remember right. Most energy is related in some way, thats what makes electric cars kinda ridiculous as its just taking the fuel at a location elsewhere. It does make sense in a city center I guess but its not magic, they still pollute
Kinda amazing oil got so high, I think its also related to a weaker then expected dollar in 2016. No more rate rises before election is my guess so I dont expect oil to go back to $20

Theres a famous Uk fund manager who says all oil companies are overvalued. Its not for this take but their ability to renew their reserves, I think the companies do track this worth themselves. The cost of oil is alot of cases finding the resource to begin with and then establishing a line of supply, refining. Once its all setup for production like you listed above the deal is done but they also have to repay debt in setup. I think the hidden factor is the future these companies have or their cost of discovery. I forget the exact term, BP and Rosneft are partly merged due to BP owning large Russian reserves at one point 2bn cost 20bn profit was nice
