Description of Assembled Components:
Item 1Part Number: 100-6000-210K Description: 60-48 Hydro-Set Anchor Latch Seal Unit Material: P110, K-RITE Chevron Packing Latch Thread: 6-1/2 4P Square Seal Bore: 6.000 Min ID: 4.875 (Drift 4.703 x 18" Long) Rated: 10,000 PSi @ 325 Deg F Item 2 Part Number: 090-8125-200A Description: 81-60-47 Model DB Hydro-Set Permanent Packer Setting Range: 9-5/8" 43.5-58.4 PPF (8.435 - 8.755) Material: P110, Ecner Array Aflas Packing System Latch Thread: 6-1/2 4P Square Upper Seal Bore: 6.000 Lower Seal Bore: 4.750 Rated: 10,000 PSi @ 325 Deg F Description The 81-60-47 Model DB Hydro-Set Permanent Packer is a hydraulic set one-trip completion packer, ideal for high volume production in high angle, extremely deviated wells. The DB Packer is run in on the 60-48 Hydro-Set Anchor Latch Seal Unit which is made up in the top of the packer via the left-hand square threads on the latch. The DB Packer requires some type of temporary plugging device such as a shear out plug or wireline blanking plug located close to the end of the tubing. Well preparation Prior to running packer/completion ensure the well is clean by making a scraper run to remove scale and other materials from the casing wall. Follow scraper with gage ring and junk basket. Circulate 2/3 of the wells volume with solid free completion fluid. Casing should have 100% cement bond before running in the well. Never set packer in casing collar or where milling has occurred. Always set packers in static well conditions (no fluid or gas movement). Field Assembly Procedure Install the 60-48 Hydro-Set Anchor Latch Seal Unit in top of packer wrench tight. Verify measurements shown in illustration. If an internal pressure test is required remove (4) brass shear screws and install (4) alloy steel test inserts. Test only in an approved facility. Drift test entire assembly with 4.703 OD x 18" long drift bar. Operation The packer is set by slowly applying tubing pressure. The applied tubing pressure passes through the ports in the body of the packer and forces the setting piston up. This setting motion packs off the packing element and sets the lower and upper slips. Pack off is retained permanently through use of the body lock ring located beneath the lower slips. Do not set packer in a casing joint. Begin by pressuring tubing string to 1,340 PSI to start set. Pressure is now slowly increased to 3,000 psi and maintained for 5 minutes. Slowly increase pressure to 4,000 psi and maintain for an additional 10 minutes. Shear out Subs should be dressed with a shear value above that which is required to set the packers. If a wireline blanking plug is used, retrieve using normal wireline procedures. During the setting operation of the Model "DB" Packer a hydraulic stretching of the tubing will occur and will result in the tubing being landed in tension. After running the completion to target depth, install/test tubing hanger, nipple down BOP and install tree. Release of Anchor Seal Nipple While maintaining a slight tensile load, approximately 2,000 lbs., rotate the tubing 15 turns to the right at the packer. This unscrews the anchor latch from the left-hand square threads in the top of the packer. |
