Gravel packing has been the method of choice for sand control for the last 40–50 years. Historically gravel packs have impaired the productivity of sand controlled well completions. Only recently through the use of Well Flow, Nodal or Systems Analysis1,2  has the technology from perforating, formation damage prevention, and gravel pack design been assembled in order to effectively understand these damage mechanisms. On-site supervision and execution of better designs is crucial to sand control success. Better gravel placement, downhole tools, and planning have enhanced our ability to execute, these designs.
