摘要： A bottom hole assembly (BHA) incorporates a tubular cutter driven by a downhole motor. A scraper moves into a smaller tubular to clean an area where a spear will later be engaged to the cut tubular portion. The scraper has a relatively movable mandrel that allows straight through flow into the motor or closes flow to build pressure to a telescoping jack to exert a pull force on the cut tubular after the cut is made. The spear is articulated with mandrel manipulation to grab the cut segment and weight is set down to shift the mandrel in the scraper to allow pressure buildup with rig pumps turned on to retract the jack as the BHA is held with anchors in the larger tubular. The cut segment is pulled uphole to loosen it so it can be removed from the borehole.

摘要： An example method includes introducing a string of tubing into a wellbore to perform a primary operation, the string of tubing including at least one sensor for measuring strain and at least one device operatively associated with the at least one sensor. The method further includes translating the string of tubing relative to the wellbore, imparting a load on the string of tubing when the tubing becomes stuck in the wellbore at a stuck point, and thereby generating strain in the string of tubing above the stuck point. Additionally, the method includes measuring the strain with the at least one sensor, transmitting data indicative of the strain to a surface location with the at least one device, and determining a position of the at least one sensor in the wellbore, as based on the strain, relative to the stuck point.

摘要： A packoff device is disclosed for sealing an annulus within a wellbore, and for bypassing the sealed annulus. The packoff device may include a mandrel having a bore formed axially therethrough and first and second ports extending radially from the bore. A sealing element that extends radially-outwardly from the mandrel may be positioned axially between the first and second ports, and may create a seal within an annulus between the mandrel and a casing, to isolate a portion of the annulus above the sealing element from a portion below the sealing element. A sleeve within the bore may, with the mandrel, form a channel providing fluid communication between the first and second ports. The sleeve may be movable between open and closed states. The first and second ports may be unobstructed by the sleeve in the open state, one or more may be obstructed in the closed state.

摘要： A method of deploying a jointed tubular string into a subsea wellbore includes lowering the tubular string into the subsea wellbore from an offshore drilling unit. The tubular string has a slip joint. The method further includes, after lowering, anchoring a lower portion of the tubular string below the slip joint to a non-heaving structure. The method further includes, while the lower portion is anchored: supporting an upper portion of the tubular string above the slip joint from a rig floor of the offshore drilling unit; after supporting, adding one or more joints to the tubular string, thereby extending the tubular string; and releasing the upper portion of the extended tubular string from the rig floor. The method further includes: releasing the lower portion of the extended tubular string from the non-heaving structure; and lowering the extended tubular string into the subsea wellbore.

摘要： A grip a no goes in a subterranean tool to properly position grip members held radially outward with a cone on delivery of an uphole force. In the case of a subsurface safety valve that has a flow tube the slips are wedged into the flow tube when the grip tool lands on the no go in the subsurface safety valve and is jarred up. Jarring up using spang jars and weight bars can be repeatedly accomplished without releasing the grip tool from the flow tube. Jarring down unsupports the slips to allow them to retract while one or more springs can be used to prevent a re-grip of the flow tube. The grip tool can now be pulled out of the hole with the flow tube broken loose from accumulated debris for subsequent normal operation of the flow tube with the control system for the subsurface safety valve.

摘要： This invention relates to a method for activating and deactivating a GS-tool (2) having grippers (22), tool housing (32), spindle (22), and main spring (50) arranged to pre-tension the gripper (44) towards a deactivated position as the GS-tool (2) is displaceable in a wellbore (10) in the ground. The method includes the steps of coupling the spindle (22) of the GS-tool (2) to an actuator mandrel (12) of an actuator (4); arranging an activating sleeve between the tool housing (32) and an actuator housing (14); and displacing the actuator mandrel (12) and thereby the spindle (22) relative to the tool housing (32) in a direction from the GS-tool (2) until the grippers (44) have reached activated positions by overcoming the force from the main spring (5). A GS-tool for implementing the method is also described.
