    Abstract: Methods, apparatus and articles of manufacture are provided for a configurable downhole tool. The downhole tool includes a plurality of devices 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 is detected. Each device may then begin performing its respective function or functions. For example, some devices 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 then transmits the data from the downhole tool to some remove receiving unit, which may be located at the surface of the wellbore.

    Abstract: Methods, apparatus and articles of manufacture are provided for a configurable 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 is 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: Methods are disclosed for wellbore operations in an earth wellbore with tubi ng within casing in an earth wellbore, the wellbore extending down into earth from an earth surface, the tubing including a tubing string with a lower end and extending down within the casing with the lower end at a point above a lower end of the casing, a tubing-casing annulus between the tubing and the casing sealed by a first sealing apparatus, the method including sealing the lower end of the tubing string with a sealing device to prevent fluid flow therethrough, and sealing the tubing casing annulus with a second sealing apparatus above and spaced apart from the first sealing apparatus. In certai n aspects the sealing apparatuses provide upper and lower spaced-apart primary barriers. The methods in additional aspects include making an exit opening through the tubing and an exit opening through the casing, each exit opening located between the first sealing apparatus and the second sealing apparatus . In other aspects the methods include drilling a lateral wellbore from the ex it opening through the casing. Apparatus is disclosed that is useful in such methods.
