Abstract: Methods, apparatus and articles of manufacture are provided for a configurab le downhole tool (100). The downhole tool (100) includes a plurality of devices (112 1, 112 2, ..., 112n) each of which is configured for one or more functions. At some point during operation (e.g., during system initialization), the presence of each device disposed on the downhole tool i s detected. Each device may then begin performing its respective function or functions. For example, some devices (112 1, 112 2, ..., 112n) may be configured to collect environmental data while the tool is disposed in a wellbore. In one embodiment, the collected data is provided to a transceiver . The transceiver (339) then transmits the data from the downhole tool to some remote receiving unit (120), which may be located at the surface of the wellbore.

Abstract: The present invention generally provides a downhole tool with an improved means of transmitting data to and from the tool through the use of wired pipe capable of transmitting a signal and/or power between the surface of the well and any components in a drill string. In one aspect, a downhole tool includes a body, and a mandrel disposed in the body and movable in relation to the body. A conducive wire runs the length of the body and permits signals and/or power to be transmitted though the body as the tool changes its length.

Abstract: Den foreliggende oppfinnelse tilveiebringer generelt et nedihullsverktøy med et forbedret middel for overføring av data til og fra et verktøy ved bruk av rør med ledning som er i stand til å overføre et signal og/eller kraft mellom brønnens overflate og en hvilken som helst komponent i en borestreng. Ved ett aspekt innbefatter et nedihullsverktøy et legeme og en spindel (110) som er plassert i legemet, og hvor spindelen er bevegelige med hensyn til legemet. En ledningsforbindelse (135) løper over hele lengden av legemet og tillater signaler og/eller kraft i å overføres gjennom legemet mens verktøyet skifter lengde.
