    Abstract: In one aspect, a method of communicating between an on-site location and an off-site location is provided. The method comprising providing a communications attachment that can be positioned at the on-site location. A 2 or more-way communication system is established between the on-site location and the off-site location. The actions of the on-site location are remotely monitored by input from the off-site location. In another aspect, an apparatus comprises an off-site service computer, a communications attachment, and a communications system. The communications attachment is positioned an on-site location. A communication system between the communications attachment and the off-site service computer. In one aspect, the communications attachment is secured to a hardhat. One aspect of the communications attachment provides for communication between a person located on-site and an off-site service person for failure analysis of a complex system.

    Abstract: A wellbore system with a tubular string extending from an earth surface down into a wellbore in the earth, a packer system with a selectively settable packer element, and a disconnect located between an end of the tubular string and the packer system, the disconnect operable from the surface by imposing a downward force on the tubular string. In one aspect the packer system's packer element is a tension-set packer element. A wellbore disconnect with a top sub (122), a mandrel (126) having an upper end secured to the top sub and a portion below the upper end releasably secured with at least one releasable member (138) to a carrier member (136), the carrier member having apparatus (156) for selectively gripping the mandrel, the apparatus for selectively gripping the mandrel also selectively gripping a bottom sub (144) within which the mandrel is moveable, the at least one releasable member releasable in response to a downward force on the disconnect.

    Abstract: The invention provides an apparatus (300, 400) for actuating a downhole tool (700) by utilizing a pressure differential created by fluid flowing through a restriction in a conduit (315). The conduit is in communication with a pressure sensing line (400) that is selectively exposable to areas of near the restriction in the conduit (316, 317) having different pressures. By exposing the pressure sensing line to a portion of the conduit having a predetermined pressure therein, the pressure sensing line causes actuation of a hydraulic tool therebelow. The apparatus is of particular use for a single trip sidetrack system in combination with an MWD-tool, a whipstock, and an anchor packer without a bypass valve.

    Abstract translation: 本发明提供了一种用于通过利用由流过管道（315）中的限制器的流体产生的压力差来致动井下工具（700）的装置（300,400）。 导管与压力传感线（400）连通，压力传感线400可选择地暴露于具有不同压力的导管（316,317）中的限制附近的区域。 通过将压力感测线暴露于其中具有预定压力的管道的一部分，压力感测线引起其下的液压工具的致动。 该装置特别用于单行程侧钻系统与MWD工具，造斜器和没有旁通阀的锚式封隔器的组合。

    Abstract: En fremgangsmåte og apparat for boring med foringsrør inkluderer en boresko (10) konfigurert for senere gjennomboring derav in situ, med kuttere som holdes på plass derpå i respons til de krefter som de møter under boring av borehull, men som likevel er bevegelige fra den omhylling hvorigjennom den senere boresko vil passere når den kutter gjennom den in situ boresko (10). Boreskoen (10) inkluderer én eller flere profiler derpå, hvori blad (26) som bærer formasjonsborekutterne er anbrakt. Profilene inkluderer minst ett fremspring derpå, som opptas inne i en samsvarende sliss i bladene. Bladene (26) kan også være konfigurert til å ha motsatte seksjoner som er konfigurert i forhold til hverandre til å ha en åpningsvinkel (136) på mindre enn nitti grader.
