Data in the trajectory data object is used to:
- Identify the exact wellbore position, drill bit information, and related directional data.
- Drill in a planned direction into the formation which contains hydrocarbons (the target zone) and to keep the well within authorized (lease) areas (when drilling close to lease boundaries).
- Transmit all the survey stations in real time to a directional driller to help “steer” the well towards the target zone.
- Record deviations from the planned trajectory (and correct as necessary and possible); the information collected is referred to as a deviation survey.
