Well completion performance can be improved by optimizing completion designs. Analysis of well performance data can identify the most efficient completion option for a given reservoir. Completion performance correlates with reservoir properties, so control parameters can be used to compare data across multiple wells or fields with different reservoir characteristics. Increasing permeability in perforation tunnels or perforation density is associated with higher flow rates from the well.

1. Conclusions: Well Completion Optimization
•Well performance and Skin are design variables
•The effects of completion on skin can be predicted
•Completion performance can be improved by improving completion designs
•Well performance analysis identify the most efficient completion option
•Completion performance are correlated with host reservoir properties, then
the control parameters can be used to compare multi-well data from wells or
fields with different reservoir properties.
