135584 – Next Generation Multi-Stage Completion Technology and Risk Sharing Accelerates Development of the Bakken Play

Summary

Over the last decade, an industry wide shift to unconventional plays has occurred due to advanced drilling and completion technologies allowing the recovery of previously uneconomic reserves. A notable play in this category is the Bakken formation in the Williston Basin. Through multiple case study wells and direct offset comparisons, this paper analyzes production results for two completion methods employed in the Bakken today: cemented production liners with “plug and perf” stimulation and open hole, multi-stage system completions. Additionally, production differences based on stage number, stage interval length, and 640-acre versus 1,280-acre well spacing are presented.
