Abstract:
A system for perforating a well includes a plurality of perforating guns suspended in the well from the wireline or coiled tubing. A downhole electronic command circuit is provided for firing each of the guns in response to a command signal from the surface. A conductor cable, which may be the wireline, extends from the surface to the downhole command circuit, such that command signals fire the guns in a selected order.
