Fracture and Wellbore Spacing Optimization in Multistage Fractured Horizontal Wellbores: Learnings from Our Experience on Canadian Unconventional Resources

Horizontal wellbore drilling and completion technology with multi-stage fracturing has revolutionized the exploitation of unconventional resources in North America in recent years. Many unconventional oil and gas reservoirs with ultra-low permeability have become economical as a result. Yet, the development and completion costs of these resources can be further improved by optimizing the number of fracture stages placed on each wellbore and the...
