Double check the casing
joint count.
Have contingency plan for
if the casing won’t go to
the bottom.

Wear bushing (aka wear sleeve and bowl protector): A retrievable bushing (sleeve) thatprotects the sealing surface and load bearing shoulders of a casing head or casing spool.This device prevents the damage from the drillpipe while tripping the drillpipe or from
wear cause by the rotation of the drill pipe.
A series of different size wear bushings are required based on the casing spools that areplanned to be installed. These sleeves (bushings) are installed to protect the seal areas and
the load bearing shoulder inside the casing spool, where the casing hanger will beinstalled after the cementing operation. The wear bushing running and retrieving tools are
run on a drillpipe.
THE WEAR BUSHINGSMUST BE PULLED PRIOR TO RUNNING CASING!
WITH CASING HANGING THROUGH THE CASING SPOOL, THERE IS NOWAY TO REMOVETHE WEAR BUSHING

JSA
Sue just came from a presentation about casing running safety.
• There’s a large percentage of accidents associated with running
casing.
• Very important to go thoroughly through this JSA.
Discuss the roles and responsibilities of:
• Casing Crew.
• Drilling Crew.

Topics to Cover – Running Casing
Running Casing
• Is done with the help of a Casing Crew.
• The Casing Crew is called out to the rig to provide additional
manpower to pick up the casing, screw it together with power tongs
and lower the casing into the wellbore.
• The Casing Crew also brings special casing slips called spiders
and special elevators.

Precautions
High capacity tools open very easily with light casing load.
Care must be taken to prevent accidental opening.
Some air systems prevent opening if the other component is
already open.
Good practice:
• Start string in hole with low capacity tools.
• Switch to high capacity once there is sufficient casing weight to
prevent accidental opening.

Rig up to Fill the Casing
Rig up to be able to fill the casing as it is run.
Verify fill visually.
Large diameter casing requires large capacity fill line.

Have a swage that matches the casing thread.
Using chiksan or high pressure hose rig up to circulate mud through the casing as it is run.
It is common to circulate the mud before the casing enters the open hole section below the last casing string.
Break circulation slowly by reciprocating the casing slowly to break the gel strength of the mud, which has been static now for a number of hours.
You will circulate again after getting casing run to bottom.

Make-up Torque
Determine proper makeup torque for connections.
Use only approved thread lubricants on clean threads.
Look up correct make up torque values in Baker Hughes Tech
Facts Engineering Handbook.
Proper number of turns can also be measured.
© 2016 PetroSkills, LLC. All rights reserved.
Thread Lubricant
Apply to box, not pin.
Do not use drill pipe (DP) or drill collar (DC) dope.
Standard is API Modified.
Proprietary threads – check manufacturer.
Environmental Considerations:
• Special formulations available.
• Some threads specially coated for self lube.
Friction factor – specified relative to API Mod, adjust make-up torque accordingly.
