I thought oil companies produce gas also?
Probably a bit of each.
Dunno how up-to-date this is:

As for coal, I think they might find ways to use use induction furnaces to replace coal.
Maybe big oil companies could be a technology play also, per the research.
I remember reading the earlier stuff from
Thunder Said Energy and they have criteria for their predictions based upon the level of advancement of the technologies associated with each energy source.
I can't recall the terms they used but basically they categorise each potential technological advancement. So the first category may be technologies that are
currently purely speculative, or at say the lab level only, the next may be
currently commercial trials, whilst at the most confident level are technologies that
currently have patents filed or pending approval and look like they could work. They then do a cost analysis on these technologies looking at cost/unit of energy returned. Their methodology is the reason why things like technologies around offsetting emissions from burning coal for power or increasing nuclear power usage rank at the lower end of their upside potential for future energy sources. They do a lot of work looking at patents being filed to work out which companies are at the forefront of tech development.
One thing they are resoundingly confident upon is that humanity's future energy needs will far surpass our currently available technologies/methods of production. So whilst oil may not gain any greater % of market share in the future, the amount of oil we need in the future will probably still be more than we use today.
So next time you read some 20-something or middle-aged leftie on FB ranting about the government giving approval for the expansion of some gas or oil exploration rights and how we should be turning to renewables, you know she's an idiot who has no clue about our future energy needs.
