SECTION “ii”: GENERAL INSTALLATION GUIDELINES

NOTE: Make sure you obtain and use all required personal protective equipment prior to beginning any of the procedures that follow. The following information is meant to be a generic installation guide. The casing program is the same as described on the front page. Most wellhead systems are manufactured to specific customer requirements. Hence, the procedures that are detailed in this section should be considered as general and specific only to this

particular system. ELCO recommends that running procedures always be followed for the specific system that is being run. Furthermore, ELCO

recommends that a qualified ELCO service representative always be called for any job pertaining to ELCO equipment.

Before Installation:

1. Verify all equipment used in conjunction with ELCO’s is compatible. This includes

but is not limited to the BOP stack, casing hangers, packoffs, BOP test plugs, bowl protectors, and running tools.

2. Verify the proper emergency equipment is in place and ready for installation.

3. Verify spare parts are available. Examples include elastomer seals, ring gaskets,

and metal-to-metal seals. 4. Check all attached gate valves for proper operation. 5. Verify the proper number and type of ring gaskets, studs, and nuts are available

for the job. 6. When possible, stack up the wellhead system in the shop prior to installation.

7. Make sure you have specific running procedures for the system to be installed. 8. Make sure you always measure from the rig floor (KB) to the point you will be

landing any particular item. This should be done well in advance of the actual job and recorded in your tally book.

10

SECTION 1: INSTALLATION OF THE 21-1/4” 2M x 20” SOW FLANGE 55221

Leveling The flange must be installed so that the top is level, except in cases where the surface casing is not exactly vertical. In this case, the top flange face must be perpendicular to the casing string. Otherwise there will be problems landing subsequent casing strings.

Before Installation

NOTE: Make sure all required personal protective equipment is obtained and used during this operation.

1. Check and record the inventory code of the flange to ensure the proper

equipment is on location. This code should be considered critical. The inventory code of the flange should be 55221. This code is located on the first line of the stamp mark on the flange OD after the name ELCO. Ex.: ELCO 55221.

2. Check the ring gasket grooves and mating surfaces for foreign material, burrs, or

other damage. Dress with emery cloth to restore smoothness.

3. Check compatibility with all associated equipment on location (ie. Diverters, etc.)

Preparation

1. Make rough and final cuts on the 13-3/8” casing See Sequential Drawing 1.

2. Prepare the 13-3/8” casing with a minimum 20°/30° bevel on the OD and dress any sharp edges with a file. Remove all metal shavings. (Figure 1-1)

3. Inspect casing OD for weld beads. Grind/polish any beads flush with the pipe OD to provide a smooth and uniform surface for the slip on weld. Remove all metal shavings.

4. Bail drilling fluids from the casing and any conductor pipe annulus. Clean and dry stub.

Figure 1-1

Installation Welding Welding should only be performed by a qualified welder hired by the customer. Make sure the weld area is thoroughly cleaned before welding. NOTE: Due to the variety of materials requested for use worldwide, exact weld procedures will not be supplied in this manual. A qualified welder of the customer’s choice should be utilized to weld on casing heads. The ELCO engineering department may be consulted for guidelines. Final procedures and responsibility for the weld rest with the customer’s welder. NOTE: Make sure all required personal protective equipment is obtained and used during this operation.

1. Rig the SOW Flange with wire rope harness and clamp.

WARNING: Never use hemp or nylon rope or chains to suspend or move heavy equipment. Failure to use wire rope could result in dropping the flange and causing severe injury to personnel.

2. Pick up the flange and position over the prepared stub.

3. Slowly lower the flange onto casing stub. The flange is fully landed when the casing stub bottoms against the lead shoulder at the top of the SOW pocket. Refer to Figure 1-2.

WARNING: Do not put your hands on the casing while the flange is being landed. Failure to keep hands clear could result in crushing or cutting of fingers and hands.

Figure 1-2

4. Level the flange using a sledge hammer and body weight on the chain hoist. Hit

only the bottom of the flange. If casing is not vertical, the casing head may have to be aligned with the casing to avoid drilling or installation problems later on. If casing is off vertical, consult the service manager at ELCO Incorporated for clearance before proceeding.

5. An over-pull test is recommended, and should be done at this time. Limit any over-pull to 2,000 lbs maximum.

6. Obtain and record elevation from top of casing head to rig floor.

12

SECTION 2: INSTALLATION OF THE 13-5/8” 5M C-22BP x 13-3/8” SOW CASING HEAD 21C15

Preparation

1. Make rough and final cuts on the 13-3/8” casing.

2. Check stub outside diameter and roundness to assure proper fit. Double check cut off height to also assure proper fit.

3. Bevel the casing cut to 30° from vertical outside and 45° from vertical inside. File the beveled surfaces to take the sharp edge off to ensure the seals are not cut when the assembly is lowered over the stub. Refer to Figure 2-1 for beveling diagram.

Figure 2-1

4. Inspect casing OD for weld beads. Grind/polish any beads flush with the pipe OD to provide a smooth and uniform surface for the slip on weld. Remove all metal shavings.

5. Bail drilling fluids from the casing and any conductor pipe annulus. Clean and dry stub.

Leveling The casing head must be installed so that the top flange is level, except in cases where the surface casing is not exactly vertical. In this case, the top flange face must be perpendicular to the casing string, otherwise there will be problems passing the drill bit through the head and running and landing subsequent casing strings.

13

Orientation The casing head should establish the proper orientation for the remaining completion equipment. Be sure the side outlets are orientated so that there is ample room to install the valve-removal (VR) lubricator.

Before Installation NOTE: Make sure all required personal protective equipment is obtained and used during this operation.

1. Check the ring gasket grooves and mating surfaces for foreign material, burrs, or other damage. Dress with emery cloth to restore smoothness.

2. See that all casing head Lock Down Screws (LDS) operate freely. Make sure that all LDS are fully retracted. Measure the unengaged LDS from the flange OD to the end of the LDS pin. The measurement should read 2-3/8” (dimensions are approximate). If necessary, re-torque LDS gland nuts to ensure pressure is sealed from the wellhead bore. See Figure 2-2.

Figure 2-2

3. Check compatibility with all associated equipment on location (ie. casing, BOPS,

test tools, etc.)

Installation Welding Welding should only be performed by a qualified welder hired by the customer. Make sure the weld area is thoroughly cleaned before welding. After welding and cool-down, conduct the hydrostatic test using clear water or other suitable fluid as specified by the ELCO engineering department. Test the weld to 80% of the casing collapse rating.

2‐3/8”

14

NOTE: Due to the variety of materials requested for use worldwide, exact weld procedures will not be supplied in this manual. A qualified welder of the customer’s choice should be utilized to weld on casing heads. The ELCO engineering department may be consulted for guidelines. Final procedures and responsibility for the weld rest with the customer’s welder. NOTE: Make sure all required personal protective equipment is obtained and used during this operation.

7. Check orientation of mud valve outlet to see that it will match up to the flowlines.

8. See that there is enough clearance at the site and orientate the head so that the VR lubricator may be attached for valve removal and reinstallation.

9. Remove the 1/2” plug from the casing head test port.

10. Check and record the through bore of the casing head and make sure this dimension is not less that the OD of the casing to which it will be attached.

11. Rig the casing head with wire rope harness and clamp.

WARNING: Never use hemp or nylon rope or chains to suspend or move casing heads. Failure to use wire rope could result in dropping the casing head and causing severe injury to personnel.

12. Pick up casing head and position over the prepared stub. Orientate outlet valves to required direction.

13. Slowly lower casing head onto casing stub. The casing head is fully landed when the casing stub bottoms against the lead shoulder at the top of the SOW pocket in the bottom of the casing head. Refer to Figure 2-3.

Figure 2-3

15

WARNING: Do not put your hands on the casing while the casing head is being landed. Failure to keep hands clear could result in crushing or cutting of fingers and hands.

NOTE: Additional weight may sometimes be required to force the casing head onto the casing due to seal interference and drag.

14. Level the casing head by using a sledge hammer and body weight on the chain hoist. Hit only the bottom of the flange. If casing is not vertical, the casing head may have to be aligned with the casing to avoid drilling or installation problems later on. If casing is off vertical, consult the service manager at ELCO Incorporated for clearance before proceeding.

15. Test welds to 3,000 psi or 80% of casing collapse, whichever is less. Upon completion of a successful test, bleed pressure, drain cavity, and replace all fittings. Refer to Figure 2-4.

Figure 2-4

16. An over-pull test is recommended, and should be done at this time. Limit any over-pull to 2,000 lbs maximum.

17. If an over-pull test was completed, release over-pull and retest seals per step 11.

18. Obtain and record elevation from top of casing head to rig floor.

TEST PORT

16

SECTION 3: RUNNING OF THE 13” NOM COMBO TEST PLUG 39F13

Before Installation 1. Make sure the BOP, test plug, and the casing head are compatible. 2. See that all LDS in the casing head operate freely and are fully retracted. See

section 2, step 2 (“Before Installation”) for proper position of retracted LDS. 3. Make sure the blowout preventers are open.

4. Inspect the seals on the test plug for damage and replace if necessary.

5. Make sure weep plugs are in place when testing shear or upper pipe rams.

NOTE: Remove weep plugs when testing the lower most pipe rams as this will allow pressure to escape by the plug in the event of a lower ram leak.

Running Procedure

1. Make up the combination test plug with the seals facing down, on joint or stand of drill pipe. See Figure 3-1 for proper orientation.

2. Slowly lower the test plug through the blowout preventers and riser until it lands

on the load shoulder in the casing head.

3. Open the casing head annulus valve to check for leakage past the test plug during test

4. Fill BOPE with water at this time 5. Close the preventer pipe rams on the drill pipe and test to the required pressure. 6. Upon completion of the pressure test, close the annulus valve. 7. Open the blowout preventers (ensure that all pressure has been released, this

shall be considered critical).

6. Retrieve the BOPE test plug by pulling the test plug straight up. NOTE: This procedure is written only to cover the testing of the BOP pipe rams.

SECTION 4: INSTALLATION AND REMOVAL OF THE 13” WEAR BUSHING 38F30

Before Running 1. Make sure the bowl protector, running tool, and the casing head are compatible. 2. Verify inside diameter of the bowl protector by drifting with the drill bit. The inside

diameter of the bowl protector should be no smaller than 12-5/8” in diameter (dimensions are approximate).

3. See that all LDS in the casing head operate freely and are fully retracted. See

section 2, step 2 (“Before Installation”) for proper position of retracted LDS.

4. Make sure the blowout preventers are open.

5. Make sure running tool is compatible with the drill pipe that will be utilized to run in the wear bushing.

Running Procedure

1. Invert the running tool and make up the running tool with a joint or stand of drill pipe. See Figure 4-1 for proper orientation.

2. Stab the running tool into the bowl protector and rotate to the left, counter-

clockwise, 1/4 turn or until the tool shoulders out.

5. Engage the two LDS, making sure to not over tighten. If over tightened, damage could occur to the wear bushing. Measure all LDS from the flange OD to the end of the LDS pin to ensure all LDS are in the engaged position. This dimension should be 2-1/16” (dimensions are approximate). If necessary, re-torque LDS gland nuts to ensure pressure is sealed from the wellhead bore. See Figure 4-2

Figure 4-2

6. Rotate the drill string to the right, clockwise, 1/4 turn or until the running tool shoulders out.

7. Pull the running tool straight up. The bowl protector is now secure in the casing

head and drilling may resume. NOTE: ELCO recommends that all bowl protectors be pulled and visually inspected for wear at least once after every full trip of the drill pipe. If the bowl protector appears to be wearing quickly or abnormally, ELCO recommends that a qualified ELCO service representative be consulted to determine further actions.

1. After cementing operations are complete, Pick up desired casing weight to be put

onto the casing hanger.

2. On the rig floor, place two slip plates parallel to each other, on either side of casing.

3. Wrap the casing hanger around the 9-5/8” casing, resting the weight of the hanger on the plates. Reinstall the bolt locking the hanger halves together. Remove the four slip segment bolts. Install eye-bolts into two slip segments 180 degrees apart.

4. Thread the 50ft rope through both eye-bolt holes and tie. Verify there is enough rope to lower the slips from the rig floor to the load shoulder in the head. Use a longer rope if necessary. See Figure 6-1.

Figure 6-1

5. Using the rope, lower the slips through the BOPE until they land on the load

shoulder of the casing head. Once the slips have landed untie the rope and pull through the BOPE.

6. If the pipe is centered, the hanger will drop into the casing head bowl. If not, it will

be necessary to center the pipe using the Cat line and Air Tugger.

7. Slowly slack off casing weight, transferring the load to the slip hanger.

8. Engage the LDS, making sure to not over tighten. Measure all LDS from the

flange OD to the end of the LDS pin to ensure all LDS are in the engaged position. This dimension should be 1-5/8” (dimensions are approximate). If necessary, re-torque LDS gland nuts to ensure pressure is sealed from the wellhead bore. See Figure 6-2

SECTION 7: 9-5/8” CASING STUB PREPARATION

1. The 9-5/8” casing now needs to be cut to the length required for the WHPE seal.

NOTE: Be sure to confirm proper casing cutoff height with YOUR OWN MEASUREMENTS of secondary seal depth. If necessary, make a rough cut to ensure the stub does not become too short. Casing cut too short is a severe problem. Verify the cutoff height using the scenario at hand.


2. Cut off the casing stub to 5-1/4” above the casing head flange. This height shall be considered approximate.

Figure 7-1

3. Bevel the casing cut to 30° from vertical outside and 45° from vertical inside. File

the beveled surfaces to take the sharp edge off to ensure the seals are not cut when the assembly is lowered over the stub. Refer to Figure 7-2 for beveling diagram.

SECTION 8: INSTALLATION OF THE 11” 10M x 13-5/8” 5M TUBING SPOOL 22C43 WITH WHPE SEAL 35W09


1. Check and record the inventory code of the casing spool to ensure the proper equipment is on location. This code should be considered critical. The inventory code of the casing spool should be 22C43. This code is located on the first line of the stamp mark on the top flange after the name ELCO. Ex.: ELCO 22C43.

2. Check and record the through bore ID and bowl ID of the casing spool and re-verify size. The ID and bowl dimensions of the casing spool shall be considered critical. The through bore ID of the casing spool should not be less than 10” (in diameter and the bowl ID dimension should not be less than 10-7/8” in diameter (dimensions are approximate).

3. Ensure the WHPE secondary seal is properly installed. Apply a light coat of oil to

the internal rubber seals. In steps 1 and 2 above, if the inventory codes, and dimensions do not meet the minimum criteria as described above, the bore and/or bowl sizes shall be considered undersize and the inventory items are not the items required for installation. If any of these conditions occur, consult the service manager at ELCO, Incorporated for clearance to proceed further. 4. See that all casing spool LDS operate freely. Make sure that all LDS are fully

retracted. Measure the engaged LDS from the flange OD to the end of the LDS pin. The measurement should read 4-3/4” (dimensions are approximate). If necessary, re-torque LDS gland nuts to ensure pressure is sealed from the wellhead bore. See Figure 6-1.

APPENDIX A: RETRIEVAL OF THE BACK PRESSURE VALVE

Preparation NOTE: Make sure all required personal protective equipment is obtained and used during this operation. 1. The following is a list of tools needed before running the lubricator for retrieval of

the back pressure valve (BPV): a) Parmelee or gear Wrench

b) Spanner wrench

c) R&R tool complete with pin, set screw, and 3/16” Allen wrench

d) Grinding compound

e) Any connectors needed to attach the Lubricator to the Tree Cap or Tree Assembly

f) 6# Sledge Hammer

g) 25’ Tape Measure h) 36” & 24” Steel Pipe Wrenches

2. Determine the heights of the tree. The stroke of the lubricator must be greater than the tree

3. Find out what size and style of

BPV is in the well. Determine correct R&R tool needed to remove the BPV

4. Test the lubricator by blocking

the adapter end of the lubricator and pumping water or hydraulic fluid into the lubricator. Check the seals on the unions and the packing around the gland nuts. If there is leakage, replace any damaged seals or packing as necessary, and tighten the gland nuts with the spanner wrench.

5. Attach the R&R toll to the

polished rod.

6. Close the wing valve(s) to stop the flow in the tree. 7. Open the run of the tree and check the pressure at the top of the tree. 8. Measure the approximate distance from the tubing hanger to the top of the tree.

Also measure the distance between the gland nuts of the lubricator and subtract the width of the Parmelee or gear wrench. Divide the maximum incremental distance the polished rod can be moved into the distance between the tubing hanger and the top of the tree. This will determine the how many times polished rod will have to be moved in order to reach the tubing hanger.

9. Close the Swab valve, bleed off pressure and remove the tree cap nut for the

tree cap assembly. Removal Procedures

1. Suspend the lubricator over the tree and connect to the tree cap. 2. Open all needle valves on the lubricator to allow air to flow through the tool. 3. Coat the inside of the Parmelee or Gear wrench with grinding compound, and

attach the wrench to the polished rod so that it will turn to the left. 4. Repeatedly push the rod down into the tree, rotating the rod to the left until you

feel it stop. When this happens, you have reached the BPV. 5. Close needle valves C and D on the lubricator. 6. In order to align the threads of the R&R tool with the threads in the BPV, turn the

rod to the left slowly until a thread “hop” is felt. If a thread hop is not felt, try pushing the rod down further.

7. After the thread hop remove the Parmelee or Gear wrench and attach it so it will

turn to the right. 8. Make a mark on the polished rod using some grease, so that you can keep track

of how many rotations the R&R tool makes. 9. Rotate the rod to the right, keeping count of complete rotations that the rod

makes. After 6 or 7 rotations the R&R tool will push the piston in the BPV off its seat and allow pressure to fill the lubricator.

10. Immediately, check for leaks at the gland nuts, Autoclave fittings, and the tree

connection. If there is leakage rotate the R&R tool back out of the BPV, bleed off pressure and repair any leaks. If there are no leaks proceed with removal of the BPV.

11. Continue to rotate the rod to the right. NOTE: While watching the rod, make sure that the mark on the rod goes down until the pressure is equalized. If the mark goes up – STOP! Reset the BPV and work the ROD up and down, making sure the mark goes down, until the pressure is equalized.

12. When the R&R tool has screwed into the BPV, you will feel a significant decrease in torque after 2-3 rotations. This means the BPV has broken loose from the tubing hanger. Continue rotating, and the BPV will retract from the tubing hanger. If there is no decrease in torque, reset the BPV and equalize pressure before continuing.

13. Make sure the BPV is disengaged from the tubing hanger by pulling up on the

rod slightly. If the rod does not move, the BPV is still threaded into the hanger. Continue rotating the rod until it has completely disengaged.

14. After the BPV is disengaged from the tubing hanger, retrieve the BPV by closing

needle valves A and B. Slightly open needle valve D so that pressure will bleed off slowly and will allow the differential pressure inside the lubricator to bring the BPV up.

Figure 2

CAUTION: Do this carefully, as a sudden increase in pressure could cause the rod to skyrocket out of the lubricator. Clamp on the Parmelee or Gear wrench, and rotate the rod to the right while pulling up. 15. When the rod does not move anymore, the lubricator rod should be fully

retracted. Close the Swab valve. Bleed off pressure by fully opening needle valves C and D. Check that the pressure has been bled off by pushing the rod down a few inches and observe for any additional pressure release.

16. Disconnect the lubricator from the tree cap. 17. Replace the tree cap nut on the tree cap.
