LOCATOR TYPE PACKER PLUG
Locator type packer plug is used to convert a model WC-WSSDP & WC-WLSDP retainer production packer that has been previously set, into a temporary bridge plug. It permits the performance of pressuring operation above the packer without affecting the zones below. It is attached with shear screws to a shear sub which is made up on the bottom of the work string or a retrievable squeeze tool. Set-down weight shears the screws and leaves the plug in the packer. It is retrieved with a conventional overshot.
LATCHING TYPE PACKER PLUG
Latching type packer plug is used for the same purpose and in the same way as the locator type but will hold pressure in both directions. It is run in the same way but is retrieved by holding a slight up strain and turning to the right 15 turns after engaging with a conventional overshot.
