Vice Chairman at Allied-Horizontal Wireline Services
The new Fail-safe Addressable Switch Technology adds a new dimension to electrical wireline select-fire perforating, replacing decades old pressure switch technology. FAST™ Perforating Systems provide the ability to block all sources of inadvertent current from the electrical detonators in the tool string. This includes all sources of voltage: stray, RF signal or human error (this is extremely important for simultaneous operations like zipper fracs). The wireline operator can now communicate with and control each of the sections of the downhole assembly, and the new switches can be checked before and during the wireline run, thus improving reliability.
