The DeviDrill fits directly to the standard drill string and is fully compatible with the N-size wireline system. There is no need for additional water pumps, drill strings, or survey instruments. Devico’s survey tools are a fully integrated part of the tool, as they stay on board and measure while drilling (MWD).
Coring while steering provides a complete record of the geology. It leaves nothing in the hole – except a curve. The curvature or dogleg can be adjusted from zero to more than 20 deg/30 meters but is typically aimed at 9 deg/30 meters, which is the recommended curvature from most drill rod manufacturers.
