Integrated completion design for horizontal wells in unconventional reservoirs

An integrated workflow was tested for designing completions for a heavy-oil-recovery process that involves injection and production through the same wellbore. To capture the effect of variations or uncertainties in reservoir and fluid-flow characteristics over time, the transient effects are particularly important while analyzing the long-term performance for these types of completions. The proposed integrated workflow involves initial screening and selection of flowrestricting completions that can meet the desired injection and production performance on the basis of a detailed wellbore-hydraulics- modeling tool.
