Analytical Study Examines Production of Multistage Horizontal Wells in the Bakken

摘要

Multistage horizontal well designs were first implemented in the Bakken in 2007.Since then,more than 12,000 wells have been completed in either the Middle Bakken or Three Forks zones.Early-time production rates,as measured by 180-day state-reported cumulative production,have increased fourfold during this period,during which industry has pursued a program of innovation and continuous improvement in completions technology,with production per well increasing in 10 of 12 years.Through a big data analytical study comparing geological data,completions parameters,and state-reported production results,the authors have evaluated the fundamental changes that have guided industry to these production rates during the period discussed.
