This document contains information about Eng. El Sayed Amer, a petroleum engineer who has worked for Weatherford Drilling International and as a process and production engineer for SUCO and RWE DEA. It discusses production packers, which are subsurface tools used to provide a seal between the tubing and casing. Production packers can protect the casing from corrosion, provide better well control, isolate pay zones, and prevent fluid movement between zones. They are classified as either permanent or retrievable based on whether they can be removed from the well without destruction. The document focuses on the characteristics and advantages and disadvantages of permanent and retrievable production packers.

• 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

10. Classification
Based on customer and service companies point of view
46
Service packer
Used temporary and then retrieved or milled
out after well testing, cement squeezing,
acidizing, and fracturing

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

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

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

Permanent Disadvantages
▪ Milling destroyed the packer
for retrieving

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
