PICKING UP AND LAYING DOWN THE DRILL STEM Use thread protectors when available. When threads and shoulders are unprotected, do not permit the tool joints to strike steel surfaces such as walks, stairs, steel floors, or machinery. USE WOOD SURFACES WHERE THE TOOL JOINT MAY HIT.
CLEANING AND LUBRICATION (THREAD COMPOUNDS) Pin and box threads and shoulders should be thoroughly cleaned. Use solvent and wipe dry with a clean rag. Inspect carefully for any burrs or nicks on the shoulders or threads. DAMAGED CONNECTIONS SHOULD NEVER BE RUN IN THE HOLE. After cleaning, apply tool joint thread compound to threads and shoulders with a round, stiff bristle brush. Use thread compounds containing 40% to 60% by weight of finely powdered metallic zinc. NEVER UNDER ANY CIRCUMSTANCES, USE CASING AND TUBING LUBRICANT. THREAD COMPOUND MUST BE APPLIED TO THE TOOL JOINT EVERY TIME IT IS MADE UP.
STABBING AND SPINNING THE DRILL STEM

DO NOT ALLOW THE ENDS OF THE PIN TO STRIKE THE BOX SHOULDERS, THE SHOULDER MUST NOT BE NICKED OR OTHERWISE DAMAGED. Before spinning the pipe, make sure connections are in alignment. Do not rotate the pipe too fast, especially when wobbling or grinding occurs. Extra care is necessary when a power operated spinner is used.
MAKING UP THE DRILL STEM (TORQUE) PROPER MAKEUP IS THE MOST IMPORTANT SINGLE FACTOR IN PREVENTION OF TOOL JOINT TROUBLES. (In the spaces provided on this chart, list the connections you are using and their required makeup torque obtained from either API/IADC tables or from the manufacturer’s tables.) Observe the following steps: 1. 2. 3. 4. 5. 6.
Torque measuring equipment must be used. When using tongs, it is important that line pull be measured when the line is at right angles or 90O to the tong handle. When applying line pull, do not jerk the tongs. OVER-TORQUE CAN BE JUST AS DAMAGING AS UNDER-TORQUE. Use both tongs (when tongs are used) when making up tool joints. Do not make up pipe using spinners only. Torquing devices must be used.
BREAKING IN NEW CONNECTIONS Initial makeup is most critical and extra care is essential for long troublefree service. Follow these steps: 1. Inspect the threads and shoulder for any damage. 2. Clean and lubricate as indicated above. 3. Walk in or slowly rotate joints together. 4. Make up to recommended torque. 5 . Br ea k o ut an d slowly spin out. 6. Repeat above steps.

BREAKING AND SPINNING OUT THE DRILL STEM When breaking out the joint, use both tongs (when using tongs). Always follow these steps: 1. Do not let the end of the pipe strike the box shoulder. 2. Come out of the hole on a different break each trip so that every connection can be periodically broken and its condition and torque checked. 3. When standing the pipe back, be sure the set back area is clean where the pin will rest.

LIMITATIONS ON THE DRILL STEM CAUTIONS 1. 2. 3. 4.
Most drill pipe failures are a result of fatigue. Drill pipe should be routinely inspected for fatigue cracks. Notches from stencils, grooves, tong marks, junk cuts, rotation in the slips, etc. on the drill pipe will accelerate fatigue failure. Remove damaged pipe from the drill stem immediately. Never guess at makeup torque, pipe grade, size, weight or tool joint type. LOOK IT UP!
DRILL COLLARS
CORROSION Corrosion (rust, pitting and loss of metal) is caused by mud composition and pH, formation fluid inflow, and oxygen. THE MOST SEVERE CONDITION USUALLY ENCOUNTERED IS THE PRESENCE OF SOUR GAS (H 2 S). When (H2S) is present, obtain expert advice to prevent premature failure, especially when high strength drill pipe is being used. WHEN USING WATER BASE DRILL ING FLUIDS, MAINTAIN A MINIMUM pH OF 9.5 ( 11 to 13 is PREFERRED). Determine if corrosion inhibitors in the drilling mud will be effective and economical.
HOLE DEVIATIONS Directional wells and doglegs caused by hole angle or direction change cause fatigue at an accelarated rate. If doglegs are present, it is a good practice to string ream the dogleg area. The portion of the string immediately above the drill collars is most like to fail in fatigue. These joints should be marked, inspected more frequently, and moved up the hole each trip. A shallow dogleg in a deep hole can cause as much damage as a severe dogleg down in the hole, due to the high tension load at the top of the stem.
DRILL STEM TESTS When emptying the pipe, the bottom joints are subject to collapse from the pressure of the drilling fluid. Consult an expert or the API/IADC tables for maximum external pressures. When using plastic coated pipe, limit testing to as brief a period as possible to minimize damage to the coating. DO NOT TEST IN H 2 S ENVIRON- MENT WITHOUT EXPERT ADVICE.
Divide the torque value by the effective length of the tong arm. (See figure no. 33.) This will give the total line-pull required.
HERE IS THE WAY TO FIGURE THE DRILL COLLAR MAKE-UP TORQUE YOU NEED: Example: For 42” tongs, divide by 12” = 3.5 ft. For 48” tongs, divide by 12” = 4 ft. For 50” tongs, divide by 12” = 4.2 ft. For 54” tongs, divide by 12” = 4.5 ft. For collars with 6 3/4” OD x 2 1/4” ID and N.C. 50 (4 1/2” I.F.) connections, the tables recommend 36,742ft-lb of make-up torque. Say the “effective” tong arm length is 50” then:
50” = 4.2 ft 12” Figure #33
36,742 ft-lb = 8748 lb of line-pull 4.2ft
