The IEA thinks a supply crunch is coming

Production will not keep pace with demand within a decade unless drillers start spending money again, the agency says

A dearth of upstream investment is threatening global energy security and could lead to a 16m b/d supply shortfall by 2025, according to the International Energy Agency (IEA).

As oil prices crested in 2014, upstream investment reached a record high of $0.78 trillion, the IEA's latest World Energy Outlook (WEO) says. Oil price weakness last year cut this to less than $0.6 trillion. The IEA expects another $140bn to go unspent in 2016. If so
