Packers

A packer is a tool, which when set, seals the annular space between two strings of pipe or a string of pipe and the open hole.

The Main Functions of a Production Packer

• To keep formation pressure off the casing
• To keep formation gases or fluids off the casing
• To isolate zones or bad casing
• To hold kill fluids in the annulus
• To keep gas lift pressure off the formation
• Safety
• Test Formations
• Gravel Pack

Factors to be considered in Packer Selection

• Well Conditions
  • Well Pressure
  • Pressure Change
  • Corrosive Agents
  • Longevity of a Producing Zone
  • Well Treatment
• Compatibility with Other Downhole Equipment
• Customer Preference
• Economics
• Setting Accuracy

Production Packers

• Permanent Packers
• Sealbore Retrievable Packers
• Mechanical Retrievable Packers
• Hydraulic Retrievable Packers

General Characteristic Of Permanent Packer :

• Permanently set
• No weight or tension requirements
• Economical
• Highest pressure rating
• High temperature rating
• Popularity
• Seal assembly required and accessories can be used with permanent packers.

Oil Tools Quick Set - D Permanent Packer

Features

• Can be Wireline, Hydraulic or Coil Tubing Set
• Holds pressure from above and below
• One piece packing element and metal back up rings combine for a superior seal
• Case-hardened, drillable one-piece slips virtually eliminate premature setting
• Utilizes Baker style Anchor Latch, Snap Latch or Locator seal system
• Utilizes Shear Pin Setting mechanism for easy set up and secure running
• Optional bottom sub configurations to accommodate Seal Bore Extensions,
• Millout Extensions or Tubing
• Requires tubing seal assembly

Benefits

• Inexpensive
• Parts interchangeable with equipment from other manufacturers

Applications

• Production
• Testing
• Treating
• Gravel packing
• Multilateral

Setting Method

• Wireline Setting
  • Quickset-D can be set with Baker 20# Wireline Setting Tool while using Wireline Adapter Kit.
  • Install the wireline adapter kit in the packer.
  • The packer and adapter kit are then connected to the setting tool.
  • These are run to setting depth on the electric wireline.
  • A small charge of electrical current, transmitted through the electric wireline, ignites the power charge in the setting tool, gradually building up gas pressure.
  • This pressure provides the controlled force necessary to set the packer.
  • When the prescribed setting force has been applied to the packer, the shear pins which connect the top sub of the packer and the inner adapter of the wireline adapter kit will be broke thus freeing the setting tool from the packer, allowing it to then be retrieved.
  
  
  
• Hydraulic Setting
  • Quickset-D can also be set on tubing or drill pipe using Baker 20# Hydraulic Setting Tool and the same Wireline Adapter Kit.
  • It is particularly useful for setting permanent packers in high-angle, deviated wells such as those drilled offshore.
  • The packer is run to setting depth on the tubing string and a ball is dropped to the ball seat in the setting tool.
  • Sufficient tubing pressure is then applied to set and pack-off the packer.
  • The pressure, or combined pressure and tubing tension, then shears the shear pins which connect the top sub of the packer and the inner adapter of the wireline adapter kit.
  • It frees the setting tool from the packer for retrieval. while using Wireline Adapter Kit.
  • Install the wireline adapter kit in the packer. The packer and adapter kit are then connected to the setting tool.
  • These are run to setting depth on the electric wireline.
  • A small charge of electrical current, transmitted through the electric wireline, ignites the power charge in the setting tool, gradually building up gas pressure.
  • This pressure provides the controlled force necessary to set the packer.
  • When the prescribed setting force has been applied to the packer, the shear pins which connect the top sub of the packer and the inner adapter of the wireline adapter kit will be broke thus freeing the setting tool from the packer, allowing it to then be retrieved.
  
  
  

Locator

This is a device that connects the tubing string and the permanent packer, with the proper seal units is used as a seal between the tubing string and the packer, protecting the annulus against corrosive fluids.

Seal Units

Used with the proper guides are designed to move inside the sealbore and obtain a seal between the tubing string and the packer.

Sealbore Extension

Sealbore Extensions extend the polished surface below the packer to enable the use of longer seal units to compansate for tubing contraction or elongation. The length depends on the well conditions.

Millout Extension

Millout Extensions provide a large ID below the packer sealbore, or sealbore extension, which allows a single-trip packer milling/retrieving tool to be used when tubing is run below the packer assembly

Adapter

Connects two different sizes of pipe, and or different threads

No-Go Landing Nipple

This nipple has a reduced ID, serve the same purpose as the selective nipples but only one No-Go Nipple with same ID can be place in the tubing string, must be below the selective nipple, and normally placed at the bottom of the tubing string.

Wireline Re-Entry Guide

Short piece of beveled pipe, placed at the end of the string to allow easy re-entry into the tubing of wireline tool strings.
