n: 1. in directional drilling, the direction of the wellbore or of the face of a deflection tool in degrees (0-359") clockwise from true north. 2. an arc of the horizon measured between a fixed point (such as true north) and the vertical circle passing through the centre of an object.

n: Reflecting the direction of wellbore deflection.
