Abstract
Was M. King Hubbert, the famous American Earth scientist, really the first visionary to talk about peak oil? Indeed, many regard Hubbert as the Nostradamus of the oil industry, with his 1950s analytic work on peaking oil production part of any discussion about world oil supply today. But on the other side of the Atlantic Ocean, John Cadman was an oil oracle too, predating Hubbert by 30 years. Though Cadman's thoughts about the future of oil were more qualitative, we are witnessing his important prophecies today. In the end, Hubbert's numerical analysis and Cadman's astute foresights go hand in hand. A geologist by training, Cadman eventually became Chairman of Anglo-Persian, the predecessor company to British Petroleum, which has evolved into today's BP. Accepting the Chairmanship of Anglo-Persian on 2 November 1927, Cadman said in his inaugural address, "Very many years must elapse before natural petroleum resources will be unable to meet the greater part of the world's requirements. Of course, the time will eventually come when the world may have to look for a great part of its supplies from secondary and synthetic sources." Fast forward 80 years. Enough time has passed to have seen many of the world's prime hydrocarbon reservoirs mature. Big oil exploration has gradually migrated from the easy geographies of Pennsylvania and Texas to the deep offshore waters of the Gulf of Mexico. Internationally, megascale oil projects today are found in places such as offshore Africa, the offshore Arctic waters of Russia, or many other places that are at what I call the "ends of the Earth"—geographically extreme places where the oil is buried deep under water and rock. In addition, a lot of oil is buried under deep layers of authoritarianism, corruption, civil strife, and geopolitical intrigue. On the demand side, the President of the United States has acknowledged that the United States is "addicted" to oil. But the addiction does not end at the U.S. border; the craving for oil is global. Using Cadman's phrase for consumption: "The greater part of the world's requirements" is now a thousand-barrel-a-second oil dependency that is growing relentlessly year after year. So, the time has come. The world's requirement for more and more oil is taxing the industry's ability to supply it easily. We have finally reached Cadman's point of transition, where the world needs to look for a great part of its oil supplies from "secondary and synthetic sources." Where is this happening on a big scale?

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
