Abstract: A downhole modular tool includes a first module, a second module, a third module, and one or more connectors for connecting the first, second, and third modules. Each module includes a drill collar, a drilling fluid passageway, a first fluid passageway, and a second fluid passageway. The one or more connectors connect any one of the first, second, and third modules, to another of the first, second, and third modules to transfer the drilling fluid, the first fluid, and the second fluid between the connected modules.

Abstract: The present disclosure relates to valve systems that include valve shift detection systems that can be employed to determine when a valve has shifted. According to certain embodiments, the valve shift detection systems may include a switch integrated into a valve block that may be closed upon shifting of the spool valve. In certain embodiments, the switch may include a component that completes a circuit upon contacting the valve. The valve shift detection systems also may include a controller designed to detect a voltage or current change produced by completing the circuit.

Abstract: Systems, methods, and devices for fault detection and tolerance in a downhole tool string are provided. If a fault is detected in an electrical path between tools of downhole tool string, one or more switches of a fault detection and tolerance circuit may be kept open to isolate the fault in an electrical path between tools of downhole tool string. If a fault is not detected, one or more switches of a fault detection and tolerance circuit may be closed to enable the transmission of signals on the electrical path. In some embodiments of fault detection and tolerance circuits, an additional one or more switches may be kept open to isolate the fault in electronics of the tool.
