    Abstract: An apparatus for facilitating the connection or disconnection of a tubular t o or from a string of tubulars, which apparatus comprises a weight compensatin g device (20) which can be suspended from a travelling block (6) or a top driv e characterised in that said apparatus further comprises at least one bail (2) which can support a primary elevator (10) and which can, in use, be raised a nd lowered by said weight compensating device (20) to enable a tubular (32) to be raised and lowered with respect to a string of tubulars and which can move t o a load bearing position in which it can raise and lower said string of tubulars. An apparatus for facilitating the connection or disconnection of a tubular to or from a string of tubulars, which apparatus comprises a weight compensating device (20) which can be suspended from a travelling block (6) or a top drive characterised in that said apparatus further comprises a member (42) which can support a primary elevator (10) and which can, in use, be raised and lowered by said weight compensating device (20) to enable a tubul ar (32) to be raised and lowered with respect to a string of tubulars and which can move to a load bearing position in which it can raise and lower said string of tubulars wherein said weight compensating device (20) is arranged between said travelling block (6) or said top drive and said primary elevato r (10). This invention also provides a method, a device and an elevator.

    Abstract: A new elevator for use in wellbore operations has been invented which, in certain aspects, has a first body part, a second body part, the body parts together defining a interior opening through the elevator for accommodating a wellbore tubular therein, first hinge apparatus hingedly connecting the two body parts together and permitting the two body parts to be hingedly openable on a first side of the elevator, and second hinge apparatus disposed across from the first hinge apparatus, the second hinge apparatus hingedly connecting the two body parts together and permitting the two body parts to be hingedly openable on a second side of the elevator. In certain aspects such an elevator has at least one roller secured to an interior of at least one of the body parts to facilitate movement of a wellbore tubular with respect to the elevator, and inparticular aspects has a plurality of spaced apart rollers. In one such elevator the plurality of rollers is one or more rollers on each body part.

    Abstract: An apparatus (101) is provided with position sensors. When the apparatus (101) has moved one tubular into alignment with another tubular a button on a remonte control console is pressed to memorise the position. After the next tubular has been gripped by the apparatus a "recall" button is pressed and the apparatus (101) automatically moves the next tubular to the memorised position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.
