I have always been sceptical of the extensive theories of peak oil built around the study first published in 1956 by M King Hubbert. Those studies have always seemed to ignore the reality of technical progress that opens new frontiers and reduces costs. They have been much used to support the idea that oil prices should be ever increasing, on the basis that scarcity should be reflected in high prices.
The reality is that oil provinces (think of the North Sea) keep going well beyond their original schedule, and recovery rates from established fields keep rising. On average, even after some advances in reservoir management technology, only some 50 per cent of the oil in place is recovered from most fields, so there is a long way still to go. On top of that, we now have tight oil (the oil equivalent of shale gas), which BP in its latest Long Term Outlook now expects to provide some 9 per cent of global production in 2030. Read more
