World oil production is about to reach a peak and go into its final decline. For years, a handful of petroleum geologists, including me, have been predicting peak oil before 2007, but in an era of cheap oil, few people listened. Lately, several major oil companies seem to have got the message. One of Chevron’s ads says the world is currently burning 2 bbl. of oil for every barrel of new oil discovered. Exxon Mobil says 1987 was the last year that we found more oil worldwide than we burned. Shell reports that it will expand its Canadian oil-sands operations but elsewhere will focus on finding natural gas and not oil. It sounds as though Shell is kissing the oil business goodbye. M. King Hubbert, a geophysicist, correctly predicted in 1956 that oil production in the U. S. would peak in the early 1970s--the moment now known as "Hubbert’s Peak", I believe world oil production is about to reach a similar peak.
