· Cavity tube wells and strainer tube wells with coir strainers generally fall in this egory. The latter usually tap only the unconfined aquifer. 2. Deep tube wells Deep tube wells are wells of high capacity, tapping more than one aquifer. Their depth usually ranges from 60300 m. May be strainer wells or gravelpack wells 16.
A gravelpacked well is the well having an artificially placed gravel envelope around the well screen (Fig. ). Salient advantages of the artificial gravel pack are (Todd 1980): (i) it stabilizes the aquifer tapped by the well, (ii) it avoids/minimizes sand pumping, (iii) it allows to use a large screen slot with a maximum open area, and (iv) it provides a zone of high permeability ...
water from an aquifer comprising sand to fine gravel grain sizes. The pack is placed around the screen to help support the well walls and keep out fine sediment.
