Abstract: A method and a device for cleaning an area (48) located inside a restriction (46) by means of a mechanical cleaning tool (1). The restriction (46) having a smaller cross-sectional dimension than the area (48) to be cleaned. The method includes the steps of moving the cleaning tool (1) into or through the restriction (46); moving a mechanical cleaning body (18) radially out into abutment against the area (48) to be cleaned; rotating the cleaning body (18) relative to the area (48) to be cleaned; moving the mechanical cleaning body (18) radially in from the area (48) which has been cleaned; and moving the cleaning tool (1) out from the restriction (46).

Abstract: This invention relates to a junk catcher (2, 2?) releasably connected to a retrievable bridge plug (4, 4?) connectable to a setting tool (6) for joint deployment of bridge plug (4, 4?) and junk catcher (2, 2?) in a borehole (9) or a tubular in the borehole (9). Setting tool (6) extends through a fishing neck (12), a catcher tube (14), a flanged section (16), a valve chamber (18), a closable opening (20) and a portion of a setting sleeve (22, 22?) of junk catcher (2, 2?). Valve chamber (18) comprises a valve (50) arranged to close closable opening (20) after retrieval of setting tool (6) from junk catcher (2, 2?). The junk catcher (2, 2?) is connected to bridge plug (4, 4?) by at least one shear bolt (27, 38). Bridge plug (4, 4?) comprises a plug fishing neck (32, 32?) facing junk catcher (2, 2?), and bridge plug (4, 4?) comprises an equalizing channel (71) in a mandrel (7).

Abstract: This invention relates to a method and apparatus for retrieving a tubing from a well at least partly filled with a liquid. The tubing has first and second end portions. Method steps include: (a) running a retrieval apparatus using connecting means from a surface into the well, retrieval apparatus including: means for engaging tubing; means for sealing a portion of the bore of tubing; means for injecting a low density fluid into tubing, (b) connecting engagement means to a portion of tubing; (c) activating sealing means to close liquid communication in the bore of tubing between first and second end portions; (d) replacing at least a portion of a volume of liquid defined by sealing means, tubing and second end portion (B-B?) of the tubing by a low density fluid introduced in volume by injection means; and (e) retrieving tubing out of the well using connecting means.

Abstract: An anchor mechanism for use in a well including a housing with a plurality of openings evenly distributed along the circumference of the housing and each opening arranged to narrowly house a radially movably slip including first and second end portions, a gripping side facing a well wall, the gripping side being provided with a plurality of teeth, an underside facing the opposite direction, two side faces extending from the gripping side to the underside and to two end faces; the slip having, at its first and second end portions, with a first inclined face and a second inclined face substantially sloping from the end faces and towards the middle portion of the slip on the underside; the slip provided, on its end faces, with laterally projecting tongues having a longitudinal direction parallel to the inclined faces; the slip provided, on its two side faces, with guide portions exhibiting a longitudinal direction perpendicular to the longitudinal direction of the slip and the guide portion complementarily fitti

Abstract: This inventions relates to a stroker device (1) for use in a borehole (2) in the ground. The stroker (1) comprises at least an actuator (6) arranged for displacing a tool (10) in a longitudinal direction of the borehole (2) and grippers (26) arranged to anchor the stroker (1) to the wall (36) of the borehole (2), alternatively to a pipe wall. The stroker (1) is provided with driving wheels (34) or driving belts for propulsion.

Abstract: An actuator for connecting to and displacing of a component in a well tubular is disclosed. The actuator includes a tool shaft provided with a radial direction spring-loaded gripping device which are complementary fitting in the component.
