Rototec Conusulting offers the service Measurement of inclination and direction of boreholes.
After, or during, a borehole field has been drilled it might be useful to measure the actual inclination and direction of the borehole since it rarely is exactly what was intended to be drilled that was drilled.
The purpose might be to demonstrate that you have the boreholes where they should be, e.g.not into somenone else property or that they are having the same average spacing as in the simulation to ensureits functionality. Or simly do the measurement to have it documentated exactly where the boreholes are in the ground.
Rototec can do this measurement with stat-of-theart equipment, document the borehole field with 3D graphics and do calculations of average spacing etc.
