Abstract
Apparatus, systems, and methods, for perforating a downhole object while minimizing collateral damage to other objects, include use of a perforating device having a body, at least one fuel source having a characteristic that produces a selected mass flow rate, a selected burn rate, or combinations thereof, and an initiator for reacting the fuel to project a force through at least one port in the body. Characteristics of the at least one fuel source can include use of differing fuel types, shapes, and placement to achieve the desired mass flow rate or burn rate, and thus, a controlled force from the apparatus. An anchor or similar orienting device can be used to control the direction and position from which the force exits the apparatus. Openings formed in downhole objects can include a chamfered profile for facilitating future orientation or for injecting or removing substances from a formation.
