Sand placement apparatus includes a well screen assembly and a sand placement tool. The sand placement tool comprises a tubing extension or stinger and a slurry conduit which includes a barrel concentrically disposed around the stinger and a tail pipe extending down therefrom with a valve controlled seal sub at the lower end of the tail pipe. The well screen assembly comprises a production liner including a valve controlled seal socket, a lower or main well screen, a short length of pipe, an upper or tell-tale well screen, and the tubular mandrel of a hook wall packer. By means of this packer the liner is suspended within a well casing. The liner is positioned with its screens inside a perforated section of a well casing. The tool is positioned inside the liner by means of a sleeve anchored to the packer mandrel and adjustably positioned relative to the barrel to deliver sand-water slurry to the liner-casing annulus and build up the sand from the top of the annulus and then downwardly.
