Gas Lift
Packoff and Slim-Hole
Gas-Lift Mandrels
PM and CM-3 Series
Weatherford's McMurry-Macco® PM and CM-3 series gas-lift mandrels are
used primarily in post-completion gas-lift applications and are installed
using a packoff assembly, coiled tubing, or slim-hole jointed pipe.
Because the operator does not have to pull the primary production string
to install the gas-lift equipment, the PM and CM-3 series mandrels
provide a low-cost method of retrofitting gas-lift equipment in wells in
which a gas-lift system was not initially installed.
The mandrels are threaded on the upper and lower ends, with appropriate
threads for connection to a packoff assembly, small jointed pipe, or coiledtubing connectors. PM-1 series mandrels have an internal lug to accept
tubing-retrievable 1-in. OD gas-lift and orifice valves. PM-3 and CM-3
series mandrels have an external lug that accepts a 5/8-in. OD gas-lift
valve and orifice.
PM and CM-3 series mandrels are compatible with Weatherford's
solutions for slim-hole gas-lift applications, including TP packoffs and
related gas-lift valves, stops, and coiled-tubing connectors.
Applications
l
PM and CM-3 series mandrels are used to retrofit completions with
gas-lift and orifice valves not originally installed. They are effective in
either annular- or tubing-flow gas-lift applications.
l
These mandrels are used for deepening an injection point.
l
These mandrels are also used for bridging across mandrels spaced too
far apart for proper unloading.
l
CM-3 mandrels are typically used for slim-hole jointed-pipe installations.
l
PM-1 and PM-3 mandrels are used in packoff and coiled-tubing
installations.

Gas Lift
Packoff and Slim-Hole Gas-Lift Mandrels
PM and CM-3 Series
Features, Advantages and Benefits
l
Use of a packoff assembly, coiled tubing, or jointed pipe to install the
mandrels provides a low-cost method of installing gas-lift equipment.
l
The design of these mandrels enables the gas-lift system to operate
past failed gas-lift mandrels, thereby avoiding costly workover
operations to replace damaged mandrels.
l
The PM-3 and CM-3 mandrels have a smooth ID for easier wireline tool
passage.
l
The PM-1 mandrel uses a standard, conventional 1-in. OD gas-lift and
orifice valve for increased durability and proven performance.
l
These mandrels are integrated components of Weatherford’s slim-hole
retrofit gas-lift solution.
