Citigroup's global head of commodities research, discussing oil supply and the reasons he thinks future supply problems may have been exaggerated:
... TECHNOLOGY IMPROVING OIL RECOVERY
At the beginning of the shale revolution, when producers across North America were first fracking horizontal wells, companies were only able to extract a small percentage of the vast quantities of oil and gas in place. As technology has improved and operators have optimized their techniques, however, more oil has been recovered.
“We’ve seen recovery rates go from low single digits to low double digits,” Morse said. “Why is it not going to go to 30 or 40 per cent? Or why, theoretically, won’t it go to the recoverability of conventional oil at 60 per cent?”
Like improvements in capital efficiency, he said, technical improvements are boosting oil production, further improving the supply picture.
“I think you’ve got to be a technology pessimist at a period of time when it’s hard to be a technology pessimist because digitization of the entire supply chain in the oil and gas sector is just beginning,” he said...
