There are several tools that can be used to measure the deviation of the borehole path. ACT uses the Robertson Geologger®, Reflex Maxibor® or
Reflex Gyro®to map and collect coordinates. The instrument and method used to survey a hole is dictated, to an extent, by the type of hole and the lithology through which the hole has been drilled, as well as the inclination of the hole.
Data is exported to generate a graphical representation of the borehole path along the x, y, and z coordinate planes. The deviation is then plotted and displayed to show the difference between the design and survey.
The data is displayed as normal to the bearing, parallel to the bearing, and in plan view.
