                       13. Cementer must check the equipment and preferably make up and
                           dump a test batch of cement while running casing to check that all
                           lines are clear, etc.

                           Single-stage casing running procedure.

                       1. Pull the wear bushing. Change TPR to ____ and test bonnets to
                           ____ psi (call D/S when ready). Rig up to run casing, test power
                           tongs. Driller makes up a trip sheet to monitor correct displace-
                           ment. Driller holds a safety meeting on the drillfloor when ready to
                           pick up the shoe joint (call D/S and T/P when ready for meeting).
                       2. Pick up the shoe joint and test floats. Land-in slips and set safety
                           clamp. Backoff the collar, clean the threads, apply Bakerlock, and
                           make up the collar with a chaintong. Meanwhile pick up joint ____
                           on the SJ elevator, leave at the V-door on the rope, and clean the
                           threads.
                       3. Apply Bakerlock to the pin end, stab into shoe joint and make up
                           with the casing tong to ____ ft/lbs to triangle. Lower into slips,
                           apply safety clamp, and fill joint.
                       4. Repeat to Bakerlock the next collar on both sides, stabbing in the
                           float collar.
                       5. Run in, fill the casing, and pick up 10 m. Lower again and look
                           inside with a flashlight to check that the float collar allows mud to
                           flow (level dropped). Set slips and apply clamp.
                       6. Continue to RIH as per running list, applying centralizers where
                           shown (this can be done on the pipe rack). Use the safety clamp
                           (or spare SJ elevator) above slips until  ____ lbs string weight.
                           Change to spider slips and elevators before entering open hole on
                           joint ____. Fill every joint and monitor correct amount of mud
                           returned. If losses or gains suspected, F/C and call D/S immediate-
                           ly. Run in hole at about ____ minutes a joint lowering speed.
                           Cementer to prepare mixwater in good time.
                       7. Make up the casing hanger assembly. Pick out of slips and take up
                           and down weights. Open side outlets on wellhead. Break circula-
                           tion, lower casing, and land hanger; check that overstand is cor-
                           rect. Close in on TPR and pressure test above hanger to ____ psi.
                           (If emergency hanger has to be used due to casing not getting to
                           bottom, ignore this paragraph.)
