Exxon See 15% Annual Production Decline
Irina Slav via Oilprice.com:
"According to the supermajor, global oil production is facing a natural decline at a rate of some 15% annually over the next 25 years. For context, the IEA sees the rate of natural decline at 8% annually. Exxon points out, however, that the faster decline rate is a result of the shift towards shale and other unconventional oil production, where depletion happens faster than it does in conventional formations."
