The present disclosure is directed toward a downhole tool used to free stuck tools in a wellbore and the method of using the downhole tool. The downhole tool includes at least one packer element for engaging a casing in a wellbore. The packer works to isolate one area of the casing from another. The downhole tool also includes at least one slip element for engaging the casing to maintain the position of the downhole tool in the casing or wellbore. Further, the downhole tool includes a mandrel slidably disposed within the at least one packer element and the at least one slip. The mandrel includes at least one port disposed therein above the at least one packer element when the mandrel is in a first position.

A dissolvable composite slip can include at least in part a dissolvable material. A dissolvable composite slip can include at least in part a non-dissolvable metallic material. The dissolvable material should be strong enough to support the non-dissolvable metallic material which serves as teeth to set into the casing during the function of the downhole tool. The dissolvable material can include but is not limited to a polymeric material or a metallic material. At least a part of the slip is able to be set as well as be dissolved.

The invention consists a packer system for use in a well. In particular, the invention deals with a packer itself, a settling device, to settle the packer, and a retriever device, to recover the packer, it also comprises the process of operation corresponding to the system. Also comprises a process to settle with a settle device and a process to retrieve, with a retriever device, that can be used in settle and recovery processes, for delayed production of wells and the reduction of costs associated with the replacement of progressive cavity pumps (PCP).
