RETRIEVAL SYSTEM
First Claim
1. A retrieval system for retrieving a well component, such as a plug, from a well tubular metal structure having a restriction and a top, said retrieval system comprising:
- a tool string having a longitudinal extension and comprising;
a connection tool configured to connect with the well component,a force generator having a first part and a second part which is connectable with the connection tool and movable in relation to the first part for providing the axial force in the longitudinal extension, andan anchoring section having at least one projectable element for anchoring the tool string,wherein the retrieval system further comprises a safety unit surrounding the tool string and having at least one wall and at least one abutment face configured to abut the restriction, said at least one projectable element abutting the wall of the safety unit in order to anchor the tool string in the safety unit.
