Description
Bakken Formation of Eastern Williston Basin:
Impact of Completion System, Staging, and Hydraulic Fracturing Trends
This presentation will review the results of a study undertaken to analyze well completion parameters and production data for over 400 Bakken wells in the greater Sanish-Parshall area of North Dakota. The study employed Geographical Information System pattern-recognition techniques along with other data-mining techniques to interpret trends in the datasets. The study incorporated datasets from the North Dakota Industrial Commission O&G Division, public data, and in-house proprietary data.
The study examined trends in the production results for wells completed with frac sleeves and packers, plug-and-perf, and complex completions in an effort to identify differences in productivity and the completion parameters that may have contributed to same. Parameters that were studied, in addition to the type of completion, included frac fluid types and quantities, proppant types and quantities, number of stages and stage lengths, and perforation cluster spacing and length. All parameters analyzed were examined for statistical significance.
The results are significant in that they show that the application of practical data-mining techniques to an intermediate-size shale oil well dataset can reveal key learnings that may not be apparent when working with smaller datasets. The study employed merged reservoir quality proxies, well architectures, completion data, and stimulation data against which production results were placed in the geographical perspective of the Bakken formation for added interpretive value. The results can be employed in the selection of completion systems on the basis of completion time and cost balanced against the production impact of the different systems (frac sleeves, plug-and-perf, and complex systems).
