Buffett-Fit: 76/100
E&P returns track oil + gas prices more than company-specific decisions over short windows. The Buffett-quality filter for upstream: lowest-quartile breakeven cost per barrel + capital discipline (low debt + share buybacks instead of growth capex at the top of cycle). EOG Resources, Pioneer (now Exxon), and Diamondback are the modern shale templates.
