Abstract: Hydraulic fracture treatment remains an efficient and effective way to create conductive paths for increased flow tight oil reservoirs. Despite the large amounts of reserves, a tight oil well may experience lower than expected production after a fracture treatment. Thus, continued improvement of hydraulic fracture stimulation is needed and can benefit from evaluation of stimulation effectiveness. In this paper, we first understood the geological properties of the Bakken shale formation and physical relationship of well performance and stimulation treatment through a complete literature review. We then reviewed 6,000 currently producing Bakken wells in North Dakota and then chose 150 wells with enough data for further engineering and statistical analysis to better understand the underlying correlations between production and stimulation. An economic analysis was conducted for six wells to quantify the stimulation effectiveness. The new understanding helps the industry understand and optimise well completion and stimulation in the Bakken formation.
