AZIMUTH (Cont’d)
The azimuth of a wellbore at any point is defined as
the direction of the wellbore on a horizontal plane
measured clockwise form a north reference. Azimuths
are usually expressed in angles from 0-360 ,
measured from zero north.
Note: West Declination is always Subtracted and East
Declination is always Added. i.e., TRUE NORTH =
MAGNETIC NORTH ± (DECLINATION
