| Ratcheting Mule Shoe |
 The
ratcheting mule shoe is a spring loaded mule shoe re-entry tool used
to continually index or rotate when it locates the top of a shoulder
or packer.
This assembly assists in entering permanent packers as the lower
most part of the seal assembly. The ratcheting or indexing mule shoe
should be used in all completions were the ability to rotate the
tubing string is limited.
Applications include dual completion strings, control line installations
for safety valves, chemical injection completions or when the use
of down hole gauges are installed. It is available in various sizes
for the final completion.
This assembly can be retrieved with a straight over pull that overcomes
the friction of the seal units in the polished bore.
Threading can be manufactured to match production seal unit thread
specifications. We also provide the seal units for this assembly
in various element variations depending on the fluids, temperatures,
and down hole conditions. I.e. molded seals, ATR Premium, Ryton Etc. |
