Raising taxes won't assure a deal at the pump either, but I'm sure you know that, and would prefer higher prices anyway...so that alternatives look more attractive.
According to this chart, and you can rank the columns, the oil sectors don't look misplaced in the rankings relative to other industry groups. It is only the scale that is huge, not the percents. I know you hate the scale, since you don't like massive use of the product, and if the scale were smaller, it would be less bothersome to you. I get that.

This PDF is from the API, and although they meander a bit, it is still interesting, and gives their perspective about the taxing of the various sectors, compared to non-petroleum based enterprises.

To me, the taxation looks fairly reasonable but a bit heavy. I know it is from the API, and you may deem that biased out of hand, but confirm the bias, don't merely assume it.
There is more to taxation than "you have money, I've got plans, cough it up." However, depending on the plans, I do prefer the honesty of that approach to the half truths and vilification of businesses I invest in. If the plans are good, I may very well cough up...depending on whether I think my own government is lying to me and ripping me off again.
None of that in this case, they were not serious at all. I know you are Rob, but you have to see..they were not serious at all. Zero real chance, zero real intent..just electioneering only.
