Wire Line Plugs
Placed in tubing string to hold a column of fluid from draining back into the well formation.
The BT WJ consists of six components:
2. Shear Disc
5. Packing Sub
BT WJ valves are generally placed in a well when there is a need for fluid to be
retained in the wellbore and not to be reabsorbed back into the formation of a
well, a good example of this would be above a submersible pump
Install BT WJ Valve into desired jar down running tool and lower into wellbore
to desired depth, jar packing into nipple and seat no-go, jar down to shear off
and remove toolstring from wellbore.
Install equalizing prong into desired jar up pulling tool and lower into wellbore
to top of the BT WJ Valve and pierce the equalizing plunger, wait for tubing to
equalize, pull from sealbore and remove toolstring from the wellbore.
