Azimuth

Azimuth defines the direction of the well. It is measured in a horizontal plane and is expressed as the angle from a reference plane, usually 'True North'. The horizontal plane is divided into four quadrants of 90 degrees each with the reference plane as zero. If the azimuth at a survey point is 225o, it means that the well at that point is in the 3rd quadrant and is heading in South West direction in reference to 'True North'.
