Directional Drilling Exercices Directional Drilling no.1
After a survey in a deviated well it is apparent that the target will be missed. A correction run must be made but it is uncertain whether the target can be reached within the along hole distance remaining.
Check whether the correction run will allow the borehole to pass through the centre of the target and the length of the correction run.
The hole angle = 44 deg which is acceptable therefore requiring only azimuth change.
