Abstract: The present invention generally relates to an apparatus and a method for conveying and operating tools into a wellbore. In one aspect, a method of performing a downhole operation in a wellbore is provided. The method includes pushing a continuous rod into the wellbore, wherein the continuous rod includes a member disposed therein. The method further includes positioning the continuous rod proximate at a predetermined location in the wellbore and performing the downhole operation. In yet another aspect, a system for performing a downhole operation in a wellbore is provided.

Abstract: A continuous rod string 100 is fed into in a deviated wellbore 10 from delivery reel 35. Delivery apparatus 30 provides the insertion force. The delivery apparatus 30 also includes a depth encoder 25 to record the amount of string 100 within the wellbore 10 at any given time thereby determining the position of a tool 110 within the wellbore 10. Data measured and recorded by the downhole tool 110 is then correlated with the depth encoder reading thereby defining the position of the tool 110 in the wellbore 10. This information is then used to form a "log" of measured data as a function of depth within the wellbore 10 at which the data is recorded. A communication line 105, which may be electrical or fibre optic, transmits signals from or to a downhole apparatus 110 such as a logging device or pump.

Abstract: The present invention generally provides methods and apparatus for reduci ng noise in a detected electromagnetic wave used to telemeter data during a wellbore operation. In one embodiment, two surface antennae are placed on opposite sides of the wellbore and at the same distance from the wellbore. The signals from the two antennae are summed to reduce the noise in the electromagnetic signal transmitted from the electromagnetic downhole tool.

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.

Abstract: A compact, robust, wear resistant, and high performance electrically insulating gap sub for use with borehole EM Telemetry is disclosed. In one embodiment, the gap sub may include an externally threaded mandrel separated from an internally threaded housing by a dielectric material. Additionally, some embodiments may include an external gap ring for separating the upper and lower electrical halves of the sub which offers structural support, acts as the primary external seal, and provides an abrasion resistant non-conductive length on t he exterior. Some embodiments may include torsion bins to prevent the possible unscrewing of the dielectric filled threaded sections should the dielectric material become damaged or weakened.

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: 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 pip e capable of transmitting a signal and/or power between the surface of the wel l and any components in a drill string. In one aspect, a downhole tool include s a body, and a mandrel (110) disposed in the body and movable in relation to the body. A conducive wire (135) runs the length of the body and permits signals and/or power to be transmitted though the body as the tool changes i ts length.
