| If wellbore deviation and bedding dip are in same direction | |
| bed dip from horizontal(0 to 90) | |
| wellbore deviation from vertical(0 to 90) | |
| angle between bedding and wellbore | |
| calculation | |
| If wellbore deviation and and bedding dip are in directions 180 degrees apart | |
| bed dip from horizontal(0 to 90) | |
| wellbore deviation from vertical(0 to 90) | |
| angle between bedding and wellbore | |
