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.
