Abstract
The present invention provides a tool capable of being set and released. A novel arrangement of a push sleeve in the spring body eliminates several shear pins while an internal J slot formed directly on the mandrel significantly reduces the size of the lower drag body and thus the length of the tool. An internal pathway between the inner mandrel and the mandrel body selectively provide increase flow through the packer tool to facilitate running in of the tool.
