Title: Quantifying the factors influencing gravel placement and productivity of an internally gravel packed completion based on field data analysis

A detailed analysis of 341 internally gravel-packed zones in wells from three oil fields was carried out to determine which parameters significantly influence the placement of the gravel in such a completion and the well`s resulting productivity. The database analysis demonstrates that, in addition to the well-known impairing factors, such as dirty completion fluids and viscous fluid-loss control pills, the performance of gravel packs can be improved by increasing the number of perforations--especially in 7 inch completions. This suggests that the perforation tunnel is the most critical area in an internally gravel-packed completion.
