A packing assembly which is connectable to reeled tubing and which can be inserted in and pushed through a wellbore tube by the reeled tubing. The packing assembly is hydraulically set in a locking and sealing position in the wellbore by fluid introduced from the reeled tubing and, after use, is hydraulically released and removed from the wellbore. An actuating apparatus is provided for hydraulically actuating the packing assembly and can be converted in a manner to pull the packing assembly from the wellbore. Prior to the removal of the packing assembly from the wellbore, the wellbore fluid pressure is equalized across the packing assembly.

Packing assembly for use with reeled tubing and method of operating and

A well tubing extension joint including a trash barrier. A top sub having an internal locking recess is connected on the upper end of a well packer mandrel. A trash barrier is connected on the lower end of an upper tubing string for releaseably engaging the top sub to permit the upper tubing string to move longitudinally relative to the packer and packer top sub. The trash barrier includes a body having locking collet fingers for releaseably locking the body in the top sub at the locking recess. The body has external rings seals for sealing with the top sub and an internal wiper seal for sealing with the upper tubing string extending through the body. The upper tubing string has a seal moveable along the packer bore and includes a tubing joint coupling which is releaseably connectible in the trash barrier body permitting the trash barrier to be run into the well and landed and locked in the top sub, and thereafter the tubing string is released from the body for longitudinal movement in sealed relationship through the wiper seal. In two forms of the invention the upper tubing string is connected to the trash barrier assembly body only by shear pins. In the other form of the invention, the coupling is connected by shear pins and a threaded connection.
