摘要： An apparatus and method to complete a lateral wellbore that can be utilized for existing or new wells. The apparatus can be set in tension with positive confirmation on surface of correct orientation and position. Additionally, the apparatus does not restrict the internal diameter of the liner or the central wellbore and permits full access to both the lateral and the primary wellbore below the junction. The invention includes a tie back assembly (140) disposed at an upper end of a liner string (135). The tie back assembly (140) includes a hanger (150), a packer (145) and a tubular housing (175). The housing includes a liner window (155) formed in a wall thereof to permit access to the lower primary wellbore. An inner tube (185) is disposed within the housing and includes a key (180) disposed on an outer surface for alignment with a window (105) formed in a wall of the casing and a no-go obstruction (190) with is constructed and arranged to contact a lower portion of the casing window to axially locate the tie back assembly in the primary wellbore.

摘要： A deployment tool (42) for communicating a well tool from a generally vertical wellbore (12) to a lateral wellbore (14) includes a hollow tube (44) having a generally uniform inside diameter. The tube includes at least one flex portion (50) disposed intermediate a first end and a second end of the tube to allow for angular deflection of the second end (48) of the tube with respect to the first end (46) of the tube. The flex portion also maintains the generally uniform inside diameter of the tube during the angular deflection. The deployment tool also includes a locking device (64) attached to the first end of the tube for releasably securing the first end of the tube at a selected location in the vertical wellbore adjacent to the lateral wellbore. The tube of the deployment tool includes a length selected to allow the second end of the tube to extend into a portion of the lateral wellbore when the first end is releasably secured at the selected location in the vertical wellbore.

摘要： A subterranean well system and a process for drilling and completing such a system from a first subterranean well bore (54) which extends to the surface of the earth. A second well bore (55) may be drilled from the first well bore (54) and a first tubular (120) of a multiple well drilling template (100) can be positioned within the first well bore while a second tubular (130) of the template (100) can be positioned within both the first and second well bores (54, 55). Additionally, a third well bore can be drilled from the first well bore (54) and the first tubular can be further positioned therein. The first and second well bores (54, 55) can penetrate subterranean formation(s) or additional well bore(s) can be drilled from the first, second and/or third well bores (54, 55) so as to penetrate subterranean formations. A second multiple well drilling template may be utilized to drill such additional well bore(s) from the second or third well bores (55). Fluid is produced from subterranean formation(s) to the surface via said first, second, third (54, 55) and/or additional well bores (60, 70) and/or through production casing and/or tubing positioned therein.

摘要： Diverter tool (10) for diverting a pump-down tool (PDT, 22) along various branches of a pipeline (14). The diverter includes a flapper (20) to redirect the PDT along an alternate conduit (15) of a wye-section (16) of the pipeline. The flapper is hydraulically operated by an actuation chamber (19) at the lower end of the diverter. The entire diverter tool is capable of being installed in a side-pocket mandrel (12) of the pipeline adjacent the wye-section using such standard oil field equipment as a kickover tool. The entire diverter is also easily removable for servicing using a standard kickover tool.

摘要： A downhole system is deployed on wireline and includes a tool and a guide system on it a lower end of the tool for navigating past obstacles within a wellbore. A selectively rotatable tip member projects downward from the guide system. A side of the tip member is curved, so when the tool encounters an obstacle downhole, the tip member rotates so the curved side faces the obstacle and the downhole system can be urged past the obstacle. The guide system includes a sleeve and pedestal that abut one another on opposing ends that are complementarily profiled. When the sleeve and pedestal axially contact one another, the profiled ends produce relative rotation of the sleeve and pedestal. The pedestal is coupled with the tip member and the sleeve is coupled to the tool, so that the relative rotation of the sleeve and pedestal causes the tip member to rotate relative to the tool.

摘要： Adjustable drill string housings are described for use in the directional drilling of wellbores, e.g. wellbores for hydrocarbon recovery wells. The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected.
摘要翻译：描述可调节的钻柱壳体用于井筒的定向钻井，例如，烃回收井井筒。可调节的钻柱壳体允许调节壳体中的弯曲角度而不从壳体移除壳体。在一些示例性实施例中，可以通过改变由壳体承载的支撑构件中的内部应力来调节弯曲角度。在其它实施例中，可以通过引起由壳体承载的牺牲支撑构件的故障来调节弯曲角度，并且可能通过将化学品通过化学物质输送系统递送到牺牲支撑构件而引起故障。操作可调节钻柱壳体的方法包括多侧钻孔操作，其中当检测到壳体窗口时调整弯曲角度。

摘要： Disclosed embodiments may relate to devices or tools for diverting flow within a wellbore. For example, disclosed tool embodiments may allow for more efficiently cutting and pulling of casing from a wellbore during well abandonment operations, since diverting fluid flow as disclosed may allow for a single tool string trip to allow the flow patterns for both cutting and cleanup.

摘要： A method of orienting a well tool can include setting down weight on an orienting device, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, and after the securing, engaging the engagement member with an orienting profile. Another method of orienting a well tool can include compressing the orienting device between sections of a tool string, thereby securing in position an engagement member that was previously free to displace circumferentially in the device, the securing step including deforming a structure of the orienting device, and after the securing, engaging the engagement member with an orienting profile.
