The latest EIA drilling productivity report (11th April 2016) https://www.eia.gov/petroleum/drilling/ shows US shale oil production continuing to decline in Bakken, Eagle Ford and Niobrara while the Permian has flattened out. The Eagle Ford graph (Fig 1) shows that monthly declines in existing wells overwhelm production from new wells by a factor of 2.5 The resulting peak in US shale oil production gets established (Fig 2).
