Be sure to pull the wear

bushing.

Double check the casing

joint count.

Have contingency plan for

if the casing won’t go to

the bottom.

Checklist Comments


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.

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.


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.

explain how and why wear bushings are used in the process of running casing.

describe the purpose and function of casing running equipment, including casing spiders, casing elevators, power tongs, and stabbing boards.

explain the purpose and critical elements of a Job Safety Analysis document (JSA).

Make-up Torque Assignment

Find the torque make up values for the following casing string.

How will the changing torque values effect the casing tong

operator?
