Drilling Permit Definitions

A new well involves an operator drilling an original wellbore hole in the seafloor to a geologic target.

A revision to a new well involves a change to the drilling of new well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.

A bypass is when an operator drills around a mechanical problem in the original hole to the original target from the existing wellbore.

A revision to a bypass involves a change to the drilling of a bypass from an existing well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.

A sidetrack involves an operator drilling to a new geologic target or a new location within the original target from an existing wellbore.

A revision to a sidetrack involves a change to the drilling of a sidetrack from an existing well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.
