Shell is interesting study/company. Back in 2021 they released a white paper claiming that peak oil was reached in 2019, and that whitepaper market the shift in Shell as a company. They reduced investment in new oil rigs and wells, they pocket (or rather pay out) extra profits (from money not invested into new oil wells) and they seem to be trying to switch both from "growing demand" to "stable demand" and from "oil company" to "renewable company". They might pull it off, they might not, but this will be studies for decades.
