Sand Filter Media
Essential for monitoring and extraction wells in order to retain most of the formation material and to maximise hydraulic response. Made predominantly from silic sand.
 |
A well screen slot size is selected to retain about 90 per cent of the filter pack itself. The filter pack material should be well sorted to assure good porosity and hydraulic conductivity near the screen.
Good quality filter packs should have a uniformity coefficient of approximately two and be made predominantly from silica.
