From the link:

This Bakken dataset is extracted from the TGS Well Performance Database containing 11,655 wells. There were three criteria for including wells in the study: horizontal and producing from the Bakken/ Three Forks shale play; completed and put on production since Jan. 1, 2008, (looking at the last 10 years of well completions); and actively producing wells.

Each well is forecasted to economic limit using the Production Forecast Module, and oil EUR is calculated for each well.

Comparing total oil EUR to remaining oil EUR shows that only 44% of the oil has been produced from these Bakken wells. About 2.6 Bbbl of oil remain.
