摘要： An apparatus, method, and system for repairing wellbore casing. In one embodiment, an expandable casing patch system for a wellbore includes a casing patch deployment apparatus. The casing patch deployment apparatus includes a shaft having a frontward end and a rearward end as well as a thruster and a main expansion swage disposed on the shaft. The casing patch deployment apparatus also includes an anchor disposed on the shaft. The anchor is disposed frontward of the main expansion swage. In addition, the casing patch deployment apparatus includes a front expansion swage disposed frontward of the anchor and attached to the shaft. The front expansion swage has a diameter less than a diameter of the main expansion swage. The expandable casing patch system also includes an expandable casing patch.
