If the latter, he sees scope for "one more major spike in the oil price" as
I would guess it has to do with the timing issue present in harvesting shale oil. Normally with oil, you drill the well during drilling season, and then you remove the drilling rig, and move in an extraction rig. You can then extract at whatever p Fig. 4. Three types of decline model. The vertical axis is the decline rate, while the horizontal axis the production, where q denotes production and t, time. Source. environmental aspects of shale oil and gas production have not yet been investigated thoroughly and there is a risk that these parameters may slow down or limit the spreading of shale development. This report aims to examine production patterns of shale oil wells by applying decline curve analysis. The production profile of typical shale wells entails a rather sharp initial decline in the production rate and, after a few years, a much slower rate of decline. This becomes very important in determining the profitability of shale gas wells versus conventional gas wells. The average annual decline rates presented in Table 2 are based on the mean annual production decline rate of all wells with 12, 24 and 36 months of production, respectively. As seen, the decline rate is high the first year, 74%, and gradually decreases to 47 and 19% during the second and third years. EIA now provides estimates of drilled but uncompleted wells in major production regions; Initial production rates in tight oil formations continue to rise; EIA expects near-term decline in natural gas production in major shale regions; Falling rig counts drive projected near-term oil production decline in 3 key U.S. regions This trend can be seen in the continued increase in initial production rates since 2007, and it has allowed production in major shale basins to be fairly resilient despite high decline rates common to drilling and producing in tight formations and, since 2014, the declining number of rigs drilling for oil.
