Abstract
Methods and apparatus include mechanically perforating a tubular positioned in a subterranean wellbore. A plurality of mechanical penetrators are moved radially outward, simultaneously or sequentially, in response to an actuating force applied from a downhole power unit or tubing pressure. After perforating the downhole tubular, the penetrators are retracted for re-use at a new location or for retrieval. A slip assembly can secure the tool in position during use.
