Production Packer setting and types
- 1. Production packer D o w n h o l e E q u i p m e n t Eng. El Sayed Amer 06
- 2. Eng. El Sayed Amer Page 41 06 Production packer • Subsurface tool used to provide seal between tubing and casing Casing Tubing No-Go Nipple. Perfs
- 3. Eng. El Sayed Amer Page 42 Protect the Casing Formation Packer Corrosion Inhibited Packer Fluid Locator Seal Assembly Tailpipewith W/LNipple Tubing Tubing Hanger Xmas Tree Perforations Producing Fluids
- 4. Eng. El Sayed Amer Page 43 06 Production packer 1 4 2 3 5 Protect casing from corrosion Provide better well control Prevent fluid movement between pay zones Isolate zones of bad cement Protect casing from bursting Perforation Tail pipe Packer Annulus With packer fluid Casing
- 5. Eng. El Sayed Amer Page 44 06 Production packer • Slips ❑Tooth-like parts of the packer ❑Forced outward by sitting action ❑Top slips to prevent up-motion and bottom for down-motion • Packing elements ❑ Normally nitrile-rubber for moderate temperature and normal pressure ❑ Elastomers for HTHP ❑Provide seal between Csg and TBG 01 02 Cone Slips Flow mandrel Packing element
- 6. Eng. El Sayed Amer Page 45
- 7. Eng. El Sayed Amer Page 46 06 Production packer • Cone ❑ Part of the packer forced the slips to move outward 03 Cone Slips Flow mandrel Packing element
- 8. Classification Based on customer and service companies point of view 47 Service packer Used temporary and then retrieved or milled out after well testing, cement squeezing, acidizing, and fracturing
- 9. Eng. El Sayed Amer Page 48 06 Production packer Cannot be retrieved other than by milling Permanent 01 Retrieved using a special retrieving tool Retrievable Permanent 02 Released by manipulation of tubing – generally over pull or rotation Retrievable 03 01 02 03
- 10. Eng. El Sayed Amer Page 49 06 Production packer Permanent ▪ Run or set on wireline or tubing ▪ Selection depends on rig cost, service company and wellbore conditions ▪ Set hydraulically by – Pressure for tubing or drill pipe set – Firing an explosion for E-Line set ▪ Retrieved by milling
- 11. Eng. El Sayed Amer Page 50 06 Production packer Permanent Characteristics ▪ Permanently set ▪ Less costly; very low components ▪ Highest pressure rating, up to 15,000 psi ▪ High temperature rating, up to 500 F ▪ Most frequently used world wide
- 12. Eng. El Sayed Amer Page 51 06 Production packer Permanent Disadvantages ▪ Milling destroyed the packer for retrieving
- 13. Eng. El Sayed Amer Page 52 06 Production packer Retrievable • RIH on wireline or tubing • Has bi-directional slips prevent debris from setting on bottom • Main advantage is retrieving without destroying • If stuck, should be milled. • Generally milling take longer time because of harder components

- 15. Eng. El Sayed Amer Production packer setting
- 16. Eng. El Sayed Amer Page 55 06 Production packer Setting Mechanisms ▪ Mechanical ✓ Rotation ✓ Compression ✓ Tension ▪ Hydraulic ✓Pressure applied to tubing or annulus ✓Differential pressure acts on setting tool (permanent packer) or internal setting sleeve (retrievable packer). ✓Preferred method for deep / deviated wells ▪ Electrical ✓ Mechanical setting mechanism using wireline setting tool.
- 17. Eng. El Sayed Amer 06 Production packer Mechanically Set Packer ▪ Most common as retrievable packers ▪ Slips “drag” against casing ▪ J-slot mechanism prevents setting ▪ Right turn / drag frees slips ▪ Tension / set down required to maintain packer seal Compression Tension
- 18. Eng. El Sayed Amer 06 Production packer Hydraulic Set 1. Packer set using internal pressure (against tubing plug). 2. Pressure acts through port on setting sleeve. 3. Shear pin breaks 4. Setting sleeve drives bottom slips up against cone . 5. Element and upper slips energized then slips break and bite into casing Perforation Packer Annulus With packer fluid Casing
- 19. Eng. El Sayed Amer hold-down buttons Shear Pins for release Shear pins to drop Ball Pressure
- 20. Eng. El Sayed Amer 06 Production packer Wireline Set Packer ▪ Setting tool contains slow burning explosive ▪ Explosive drives down piston ▪ connected to setting sleeve ▪ Setting sleeve moves components of packer relative to each other ▪ Shear stud releases packer after setting completed
- 21. Eng. El Sayed Amer 06 Production packer E-line Set Packer
- 22. Eng. El Sayed Amer ELECTRIC CABLE FORCES CREATED BY FIRING THE CHARGE CROSS LINK FORCES DOWN THE CROSS LINK SLEEVE DOWNWARD THRUST ON TOP OF PACKER UPWARD PULL
- 23. Eng. El Sayed Amer Page 62 Permanent Retrievable Mechanical set 06 Production packer Hydraulic Set Electrical set Tubing Deploy Mud Wire line Straight Pull Rotational Release Mechanical set Hydraulic Set Electrical set Tubing Deploy Mud Permanent Retrievable
- 24. Eng. El Sayed Amer 06 Production packer Packer bores No bore – bridge plug Single Bore ✓ Used to isolate casing or tubing ✓ Used as cement retainers ✓ Used when other plugs fail to set (last resort!) ✓ Used for single completions Duel Bore ✓ Used for dual completions Packers can be defined as:
- 25. Eng. El Sayed Amer 06 Production packer 1. bridge plug
- 26. Eng. El Sayed Amer • Run on electric wireline or tubing. • Used in gravel pack completion and sand control system. • Has single bore to locate seal assembly 06 Production packer 1. Sump packer
- 27. Eng. El Sayed Amer Completion Installation Sump Packer 1. Run & Set Sump Packer
- 28. Eng. El Sayed Amer 06 Production packer 2. Single Bore
- 29. Eng. El Sayed Amer 06 Production packer 3. Duel Bore Unidirectional slips Sealing or packing element Dual tubing strings
- 30. Eng. El Sayed Amer Page 69
- 31. Eng. El Sayed Amer 06 Production packer ✓ Installed in the tailpipe to accept a plug to: ✓ isolate production from perforations below the packer (safety barrier) ✓ Pressure test the tubing string above it ✓ Set a hydraulically set packer ✓ Must be installed below the Mill-Out Extension and above any perforated joints Tailpipe Isolation Nipple CN05527
- 32. Eng. El Sayed Amer Page 71 In gas lift well To keep casing pressure of the formation To facilitate kick-off. To prevent produced (abrasive?) fluids from passing through the Gas lift-Valves
- 33. Eng. El Sayed Amer 06 Production packer ESP Packer ✓ single-bore, hydraulic-set packer with a dual head designed to reduce the overall costs of submersible pump completions. It is made up on the tubing string allowing a full bore production tubing ID and passage of an electric cable and control line.
- 34. Eng. El Sayed Amer 06 Production packer Straddles and Pack-Off Equipment ✓ Used for remediation of wellbore deficiencies ✓ The straddle is for use in any well in which pressure communication between tubing and annulus must be sealed off.
- 35. Eng. El Sayed Amer 06 Production packer Inflatable Packer ✓ Permanent or Temporary Zone Isolation. ✓ Water Shut Off. ✓ Temporary Bridge Plug for Workover. ✓ Cement Squeeze Packer. ✓ Temporary Production Packer for Flow Test. ✓ Well Abandonment.
