2. Enhancing the value of drilling and boreholes
Drilling is the most costly part of a reconnaissance operation. The aim is to highlight the geological, hydrogeological and geotechnical characteristics of a site by drawing up maps and profiles, and expressing these characteristics in figures using appropriate tests.
2.1 Survey sheet
For each survey, a card is drawn up in which all the data are recorded:
campaign identification ;
MACHINE TYPE ;
tools used ;
casing diameters ;
feed speeds ;
water intake or loss, recovery percentage ;
description of the terrain...
