Reference Systems and Coordinates
With the exception of Inertial Navigation Systems, all survey systems
measure inclination and azimuth at a particular measured depth (depths
measured “along hole”). These measurements are tied to fixed reference
systems so that the course of the borehole can be calculated and recorded.
These reference systems include:
• Depth references
• Inclination references
• Azimuth references
