Glenn R. Bowman, Regional Drilling Superintendent, Ashland Ex- ploration, Houston, and Bill Sherer, Operations Manager, Liner Tools LC and formerly Alexander Oil Tools, Houston ASSUMING A USABLE HOLE has been drilled and correct equipment has been selected, as discussed in the first three installments of this series, it is now time to run and cement the liner. In this in- stallment a recommended running procedure is given in addition to the description of an unusual phenomenon that can occur and possibly startle the rig site supervisor. Finally, preparations for testing the liner are discussed. LINER RUNNING PROCEDURES The following procedure is taken from API Bulletin D17. The reader will note that it should be modified if the intent is to reciprocate or rotate the liner. The procedure is as follows: 1. Run drill pipe and circulate to condition hole for running liner. Temperature subs should be run on this trip if bottomhole circu- lating temperatures are not known. Drop hollow rabbit (drift) to check drill pipe ID for proper pump down plug clearance. On trip out of hole, accurately measure and isolate drill pipe to be used to run the liner. Tie off remaining drill pipe on other side of the racking board. 2. Run ______ ft of _____ liner with float shoe and float collar spaced _____ joints apart. Run liner plug landing collar _____ joints above float collar. Volume between float shoe and plug landing collar is _____ bbl. Sandblast joints comprising the lower 1,000 ft and upper 1,000 ft of the lner. Run thread locking com- pound on float equipment and bottom eight joints of liner. Pump through the bottom eight joints to be certain that float equipment is working. 3. Fill each 1,000 ft of the liner while running, if automatic fill up type equipment is not used. 4. Install liner hanger and setting tool assembly. Fill dead space (if pack-off bushing is used in lieu of liner setting cups) between liner setting tool and liner
