Patent number: 7311346Abstract: A gripper mechanism (22) suspended in a coiled tubing/wireline in a well serves to releasably hold a downhole tool or other piece of equipment positioned downstream, via a tubular connecting element (10). The gripper mechanism (12) comprises axially, two relative to each other, movable coaxial parts (18, 16), a gripping part (18) designed to grip said connecting element (10) and an actuating part (16) designed to exert a radial clamping effect on the gripping portion (18a) of the gripping part (18) when this is in engagement with said connecting element (10). The clamping effect is due to complimentary conical face on opposite sides of the two parts (16, 18) of the gripper mechanism (12) being forced against each other by the axial displacement of one part (16) relative to the other part (18) in one direction (the upstream/pull-up direction).Type: GrantFiled: September 26, 2001Date of Patent: December 25, 2007Assignee: Bakke Technology ASInventor: Stig Bakke

Patent number: 7163058Abstract: An arrangement by a hydraulic jar device, especially for use in underground wells, where the jar device is installed in a pipe string led down into the well, and designed so that e.g. a stuck object in the well may be loosened or broken up by upward or downward percussions from the jar device. The jar device is actuated by increasing the flow of drill fluid. Alternatively, the device is actuated by compression. A valve (27, 37, 38) closes off the flow of drill fluid, whereby a percussion cycle is initiated. The valve is designed so as also to seal during strong lateral accelerations.Type: GrantFiled: December 28, 2001Date of Patent: January 16, 2007Assignee: Bakke Technology, ASInventor: Stig Bakke

Patent number: 7011344Abstract: A connector for connection of a pipe end portion of coiled tubing adapted for connecting a piece of downhole equipment. The connector is formed by three separate parts that can be screwed together two and two, of which a radially inner shrinkable adapter sleeve compressively surrounded by an elongate outer adapter and connector sleeve ensures the securing of the end portion of the coiled tubing, whereas a freely projecting, internally threaded end portion of the outer sleeve ensures the connection to the remaining part of the connector in the screwing together. The connector, besides exhibiting improved tensile, flexural and compressive strength properties, is also well suited to absorb torques applied.Type: GrantFiled: June 22, 2000Date of Patent: March 14, 2006Assignee: Bakke Technology ASInventor: Stig Bakke

Patent number: 6968904Abstract: A method and apparatus for advancing a rotating motorized downhole tool for operations in oil/gas wells. The apparatus is adapted for drilling and milling away of casing sections in the wells, as preparation for plugging the same. The apparatus includes a rotating tool and a driving motor indirectly suspended on coiled tubing. The apparatus also includes a carriage connected to the motor adapted to absorb torques that occur during use. The carriage is connected to the coiled tubing via a swivel coupling such that a tensile force on the coiled tubing provides an advancing force for the tool and motor.Type: GrantFiled: February 3, 2004Date of Patent: November 29, 2005Assignee: Bakke Technology ASInventor: Stig Bakke

Patent number: 6955231Abstract: A tool adapted for changing the direction of drilling during drilling. The drilling equipment used in the drilling includes a drill string, a bent sub, a drill motor, and a drill bit. The tool is positioned between the drill string and the bent sub, includes housing elements connected to one another, and has a passage for drilling fluid. The tool can be activated for rotation of the bent sub, so that the direction of drilling is changed in an infinitely variable manner. The tool includes a valve adapted for choking the passage so that the tool can be activated for rotation, a piston adapted for forced guiding of the rotation. The guides can be formed by twisted splines formed in the wall of the passage and in the wall of the opposite piston.Type: GrantFiled: June 21, 2000Date of Patent: October 18, 2005Assignee: Bakke Technology, ASInventor: Stig Bakke

Patent number: 6915853Abstract: In connection with a method and a tool for preparing a well for the production of hydrocarbons, it is aimed at perforating a casing portion (26) and working surrounding sediment (80) in a channel-forming manner. For this purpose the tool comprises a drilling means for drilling transverse holes through the casing wall when the tool (10), which is arranged to be raised/lowered and rotated about its longitudinal axis, shared by the casing (26), is placed in a fixed position within the well, through which transverse hole (40) and into surrounding sediment a jetting hose means (42,42a) is arranged to jet/dig its way in a channel-forming manner. The drilling and jetting hose means also have inactive stand-by positions protectively retracted within the tool housing (10a), from and into which they may successively be pushed forward into active working positions and again be withdrawn, as a channel (44) is completed in the sediment (80).Type: GrantFiled: December 20, 2002Date of Patent: July 12, 2005Assignee: PGS Reservoir Consultants ASInventors: Stig Bakke, Per Buset
