Hole Monitoring Procedures While Running Casing or Tubing

This is the example of hole monitoring procedure while running casing and this will give you some ideas only. You need to adjust it to suit with your operation.

hole monitoring while running casing

  • Perform pre-job safety meeting with personnel involved in operation.
  • A Full Opening Safety Valve (FOSV) and a closing handle with correction bottom connections that fit with of drill string which is being used must be available on the drill floor at all time. Driller must check this equipment. It must leave in an opened position. It may be required to have cross over from FOSV to casing connection.
  • The Driller is responsible for well monitoring while tripping. The driller has the right to shut the well in if there is an indicator of well control or any doubt while tripping out.
  • Trip sheet must be prepared with correct drill string/ tubular displacement.
  • The Driller is responsible for well monitoring while tripping. The driller has the right to shut the well in if there is an indicator of well control or any doubt while running casing or tubing.
  • Shut In Procedure Running Casing or Tubing for Well Control Situation must be posted in the driller cabin where the driller can see it easily at all time.
    • Note: shut in procedure depends on requirement on each company.
  • Kick detection devices as flow show, Pit Volume Totalizer monitor, and alarm must be tested properly and regularly.

  • Mud logger kick detection devices must also tested in the same way as rig instrumentation to confirm an accuracy and readiness.
  • Set the trip tank gain/loss and the flow show at required level.
  • Use mud pit to monitor the well if larger casing is ran. Use a trip tank to monitor the well if a smaller casing or tubing is ran. This depends on the rig system.
  • Track volume displacement with two separate systems if possible (one from the rig system and another one from mud logger system).
  • Verify all well control equipment is properly lined up to shut the well in.
  • Confirm the correct line up for well monitoring via a trip tank.
  • Confirm the correct line up from mud pumps to the rig floor.
  • Review shut in procedure while running casing or tubing.
  • Review any foreseeable issues with Toolpusher and Customer Representative
  • Ensure correct casing or tubing tally while running in hole
  • Trip sheets must be recorded every stand of casing / tubing ran. Assistant Driller has a responsibility to accurately fill a trip sheet while running casing/tubing.
  • Trip sheets must be kept in a tool pusher office after tripping operation completed.
  • While running casing/tubing, if the volume discrepancy is seen, Assistant Driller must inform Driller, Tool Pusher and Company Representative. The running casing/tubing operation must be stopped for further evaluation and a Full Open Safety Valve must be installed.
  • Ensure shut in while running casing/tubing procedure is posted on the rig floor closed to the driller console
  • While tripping, if the volume discrepancy is seen, Assistant Driller must inform Driller, Tool Pusher and Company Representative. The tripping operation must be stopped for further evaluation and a Full Open Safety Valve must be installed.
