Abstract: The present invention relates to an arrangement for use with a plug (1) for sealing against an inner wall of a pipeline (30), comprising a main body and sealing means, which sealing means comprises an annular packer element (7), arranged between two relative movable body elements (5,6) of the main body actuated by actuation means, where the movable elements form surfaces (500,600) in abutment against the packer element (7). The packer element (7) comprises a radially inner section (705) which is mainly incompressible in a direction transverse to a circumferential direction and where sections of the two surfaces (500,600) in abutment against the inner section (705) of the packer element (7) in a retracted position, forms different angles in relation to an axis in radial direction in relation to a longitudinal axis of the plug.

Abstract: Arrangement for use with a plug (1) for sealing against an inner wall of a pipeline (30), comprising a main body, sealing means and actuation means for moving the sealing means from a retracted to an extended state in contact with the inner wall of the pipeline, which sealing means comprises an annular packer element (7), arranged between two relative movable body elements (5, 6) of the main body actuated by the actuation means, The packer element (7) comprises means (720, 722, 724, 730) in an outer peripheral surface formed by a first side (701) of the packer element (7), which means comprises at least one peripheral rib (724) radially protruding from the first side (701) of the packer element (7).

Abstract: A pulling tool for use in the placing of equipment and acquisition of data from pipes and boreholes used in the production of oil and gas. For this purpose the tool is constructed round a central, elongate, cylindrical main element (1) to which there are arranged radially movable links (2), (4) and (5) with chains (3) arranged thereto, running in grooves (11). Radial movement of the links is provided by subjecting a terminal element (9) for the links (5) to an axial movement by means of an actuator (24). The chains (3) are rotated by an electric motor (8) transferring, through the axle (9) connected to the bevel gears (18) and (17), propulsive force to the chain wheel (15) on which the chains (3) are running.

Abstract: A downhole tool for pressure testing of oil and gas wells comprises a generally tubular main tool (1), which is provided with an internal passage (2) and is arranged for attachment at the lower end of a drill pipe string. The main tool (1) is on its outside provided with an inflatable packing element (10), which may be supplied with and relieved of inflating medium via an annular slide valve (5) arranged inside the main tool (1). The slide valve has two active positions, one on each side of a closing initial position, and the slide valve is brought to the active positions by an auxiliary tool (18) which may be run into the passage (2) of the main tool and attached releasably in the slide valve (5).
