The Warrior Well Logging System consists of a tool interface and power supply panel, a computer, a printer and optional depth, line speed, line weight panel, and perforating power supply. The software supports most cased hole logging tools from a wide selection of tool manufacturers. The tool interface panel contains the necessary circuits to interface to most cased hole tools, both analog and digital. The depth encoder and line weight interfaces are built into the panel, as is the down hole tool power supply.
