During a development campaign of the Duvernay in Shell's Fox Creek area, 23 of 36 wells performed below the initial P90 expectation. The lookback required a culture of openly addressing failure. Uncertainty about the reason for underperformance and its predictability remain. Early indicators to identify the area of underperformance are discussed for three technical aspects, including an unconventional impact of high water cut on condensate production. This experience demonstrates the value of data. In hindsight, pace of development did not allow to react to learnings.
