Abstract
A retrievable production packer is conditioned for initial wireline installation in a well utilizing an adapter comprising an outer sleeve and an inner rod connected to a mandrel carrying the slip assembly of the packer. The packer is frangibly supported in an initial transport condition for being set by means of a wireline setting device. A flow control device, such as a blanking plug, may be seated in the packer mandrel at the very top of the packer while being lowered into position and set with a wireline setting device. Thereafter, the tubing string may be connected to the packer downhole to release the packer and retrieve it from the well.
