The Abandonment Valve provides a means
for temporarily abandoning a well without
tripping out a workstring. This valve is
run in conjunction with a heavy duty
service packer. The Abandonment Valve
and packer are designed to allow heavy
loads to hang through them and thus
allowing a workstring to hang below
during abandonment. The most common
use of the Abandonment Valve and
packer combination is offshore for storm
abandonment, but can also be used for
working on BOP’s during drilling without
tripping the drill string out.
This valve uses a colleted sliding
valve (lower collet) that is opened and
closed by the disconnect and reconnect
operations. The valve is designed so that
the flow slots in the valve line up with
the flow slots in the valve case to allow
for higher rates of circulation without
damaging the valve.
This valve uses a colleted latch
that has a left-hand buttress thread
allowing easy insertion of the latch
while providing a strong connection.
The colleted latch is supported during
loading to ensure the latch threads
stay completely engaged. All external
threads are locked with set screws
to ensure against backing off during
packer setting.
Special Features
> Right-hand release
> Straight set down re-attachment
> 2.75” ID with Pump-Out Plug
removed
> Screw-on casing centralizer ring
