PPT-Angles Angles Angles The distance from rotary table to Point B as measured along the wellbore

The vertical distance from rotary table to Point B is called a true vertical depth The inclination angle I is the angle between vertical and the wellbore The direction angle A is specified as the azimuth between the geographic north and the projection of a wellbore on a horizontal plane. 1.
