Pipe Sticking

Pipe Sticking

In many drilling operations, the drill string is stuck while pulling out after first having experienced tight hole, swabbing and overpulls.

This indicates the following shortcomings:

  • Pulling out has continued for too long without remedial action.
  • Drilling personnel have been allowed to struggle on their own without supervision or advice.
  • Deterioration of the hole or of the mud properties has not been detected or recognised in time prior to pulling out.
  • Incorrect practices, of which supervisory staff are not aware, have been used.
