摘要： Methods and systems to initiate downhole operations in a borehole include deploying a first structure at least partially in the borehole, moving a second structure at least partially along the first structure, wherein at least one of the first structure and the second structure is equipped with a sensor and the other of the first and second structure is equipped with a marker detectable by the sensor, detecting a critical event that is related to an interaction of the sensor and the marker, measuring a time-since-critical event, determining a time delay based on the time-since-critical event, transmitting, with a telemetry system, data from the earth's subsurface to the earth's surface indicating that the critical event has been detected, and initiating a downhole operation by using the determined time delay.

摘要： Methods and tools for cutting a component in a wellbore are include use of a downhole tool that is tripped into a wellbore. The downhole tool includes at least one sensor that determines whether a quality of a cement around casing satisfies a predetermined standard. The casing is cut to remove an axial section of the casing and the at least one sensor determines whether at least a segment of the axial section of the casing remains adhered to the cement after the casing is cut. A casing removal tool can be activated to remove any remaining segments of casing in the axial section. A plug can be formed in the area where the axial segment of the casing was removed. The downhole tool may include a cutting tool with a laser, abrasive jet, or other cutting element shielded from wellbore debris by a fluid stream.

摘要： A methodology and apparatus for cutting shape(s) or profile(s) through well tubular(s), or for completely circumferentially severing through multiple tubulars, including all tubing, pipe, casing, liners, cement, other material encountered in tubular annuli. This rigless apparatus utilizes a computer controlled, downhole robotic three-axis rotary mill to effectively generate a shape(s) or profile(s) through, or to completely sever in a 360 degree horizontal plane wells with multiple, nested strings of tubulars whether the tubulars are concentrically aligned or eccentrically aligned. This is useful for well abandonment and decommissioning where complete severance is necessitated and explosives are prohibited, or in situations requiring a precise window or other shape to be cut through a single tubular or plurality of tubulars.

摘要： Dual section mills are selectively sequentially operated by locking an actuator for the backup mill as the primary mill has blades extended with internal flow through a housing. When the primary mill is spent the support string is shifted to defeat a lock on an actuation piston for the backup mill so that its blades can extend and continue to mill to finish the job. The blades of the primary mill continue to rotate in the already milled portion of the window as the secondary mill enlarges the window. Another way the secondary mill is actuated is to open access to flow to the secondary mill by removing a pressure barrier such as a valve or a disappearing plug, for example.

摘要： Systems and methods usable in conduit cutting operations are disclosed. Specifically, an anchor assembly is configured to be attached to a cutting apparatus and to equalize the upward and downward forces on the cutting apparatus during performance of the cutting operation. In addition, the anchor assembly is configured to impart a rotational motion in the cutting apparatus to produce a clean and complete horizontal cut of the conduit at a desired location.

摘要： In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.
摘要翻译：在插头中，具有壳体和穿过套管的管状串的放弃环境将工具放置在期望的位置以切断内管。第一组叶片从壳体延伸到径向切割直到内管被切断。然后将第二组叶片延伸用于轴向研磨，其中断开的管的外壁的到达极限位于颠簸之间的位置。当轴向铣削达到镦锻时，允许第二组叶片缩回，并且具有较长距离的第三组延伸到轴向铣削镦锻。此后，允许第三组叶片缩回并且第二组延伸以继续轴向铣削。第二组和第三组叶片可以颠倒，使得初始轴向铣削可以处于不利地位，而不是在较短的接近叶片之间的扭曲之间铣削。

摘要： Methods and systems for providing or enabling cap rock restoration of at least a portion of a producible zone of a subterranean well include placing and supporting at least one cement equivalent well barrier member within an operable usable space. This cement equivalent well barrier is formed by at least one cable operable and rig-less string operable, annulus engagable member, comprising cable and rig-less string conveyable components that are conveyed through an innermost passageway and downward from a wellhead. Energy, conductible through said rig-less string or through movable fluid of a circulatable fluid column, is used to operate or access at least one annulus from said innermost passageway and displace at least one portion of a wall of at least one conduit about said innermost passageway, to provide at least one cement equivalent well barrier.
