    Abstract: A downhole arrangement (32) comprises first (34) and second (41) members, a lock profile (4) fixed relative to one of the first and second members, and a lock member (10) for engaging the at least one lock profile. A release member (40) is provided which is moveable to selectively lock the lock member in engagement with the lock profile so as to selectively secure the second member relative to the first member. Such a downhole arrangement may permit a releasable connection between the first and second members.

    Abstract: A completion apparatus for completing a wellbore includes a tool to alternatively open and close a throughbore; a tool to alternatively open and close an annulus between the outer surface of the completion and the inner surface of the wellbore; a tool to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the annulus; and at least one signal receiver and processing tool capable of decoding signals received. The apparatus is run into the well bore, the throughbore is closed and the fluid pressure in the tubing is increased to pressure test the completion; the annulus is closed and a fluid circulation route is provided from the throughbore to the annulus and fluid is circulated through the production tubing into the annulus and back to surface. The fluid circulation route is then closed and the throughbore is opened.

    Abstract: A system for use in downhole detection comprises a downhole arrangement defining a throughbore and a tool deployable through the throughbore of the downhole arrangement. The system further comprises a primary electromagnetic element provided on one of the downhole arrangement and the deployable tool and a secondary electromagnetic element provided on the other of the downhole arrangement and the deployable tool, wherein the primary and secondary electromagnetic elements are configurable for electromagnetic coupling therebetween. Such a system may be used for determining a status and/or an identity of a downhole tool in an oil or gas well from a determined degree of electromagnetic coupling between the primary and secondary electromagnetic elements.
