A well installed into a confined aquifer with a porosity of 0.3 and saturated thickness of 80 ft. The gravel pack requires a well screen slot width of 0.025 inches. The hydraulic conductivity of the aquifer is 60 ft/d. The radius of influence is 1200 ft and the hydraulic head at the radius of influence is 520 ft. The maximum permissible drawdown at the well is 25 ft. Determine the length of the well screen, the diameter of the well screen, the per cent open area of the well screen, the thickness of the gravel pack, the formation drawdown, the well screen drawdown, and the actual entrance velocity. The flow rate from the well should be greater than equal to 96000 ft^3/d. Locate the well screen in the middle of the aquifer formation.
