Extending reserves may help on short term but won’t create more oil on earth.

A better medium/long term strategy seems to reduce oil energy usage or speed up transition on other energy sources and usages. This will also have the strategic advantage of keep on the technological race.

My naïve view would be to priorise the reduce way over transition one because other techs also needs material extracted from earth, refined, transformed, move sub-continent… and that also need a lot of energy. I’m not an expert and would love to be proven wrong, and see a fast enough global transition.
