The paper deals with the comparative study of the transmissivity values obtained by slug-tests and pump-tests on 58 wells drilled by DTH rigs in crystalline rocks comprising granites, gneisses, schists and basalts. The present study indicates that transmissivity values obtained by two methods vary mostly within a factor of three, except for pump-test T values of less than 10m2/day.

Exploratory wells drilled in pegmatites in Karnataka, Kerala and Tamil Nadu have recorded high yields. The median specific capacity value is 80 1/min-m. A commonly observed phenomenon is that discharge of a borewell increases immediately after striking pegmatites. The detailed, long duration pump tests conducted also indicate their sustained high performance.Keywords
