Abstract
A downhole running and expansion tool for mounting on a string in combination with a length of expandable tubing, the tool including a mounting portion defining a ratchet thread for engaging a corresponding thread defined by the expandable tubing, the thread preventing axial separation of the tool and tubing and releasably restraining the tool against axial movement into the tubing. Releasable retainers, such as shear pins may also be provided between the tool and tubing. On reaching the desired location in a bore, a combination of downwards jars and weight release the shear pins and moves the tool thread past the tubing thread. The tool includes an expander cone which is pushed through the tubing to expand the tubing to the desired diameter.
