D&L On/Off Tool

The D&L On/Off Tool is a fully machined, weld-free tubing seal receptacle allowing isolation of a lower zone using a wireline blanking plug. The tubing string can then be removed from the well. When re-run, the tubing string automatically re-engages to the stinger, and the blanking plug can be retrieved by wireline. 

The D&L On/Off Tool is run above an ASI-X Packer, a VSI-X Packer or a Permapak Seal Bore Packer with a latch seal mandrel.

The D&L On/Off Tool is fully compatible with D&L’s existing DT-2 Stingers and On/Off Tool Top Subs. Utilizing a common J-body among all casing sizes (per connection / stinger size) translates to less inventory items for customers to stock. Interchangeable milling shoes are available in all casing sizes to quickly and easily convert from one size to another.
