摘要： Systems and methods for sealing a wellbore are described. The system includes a packing element configured to at least partially seal an uphole portion of a wellbore from a downhole portion of the wellbore. A first annular pressure sensor is positioned uphole of the packing element. The first annular pressure sensor is configured to measure a first pressure within the wellbore uphole of the packing element. A second annular pressure sensor is positioned downhole of the packing element. The second annular pressure sensor is configured to measure a second pressure within the wellbore downhole of the packing element. A control sub-assembly is configured to be positioned within the wellbore. The control sub-assembly is configured to monitor a sealing efficiency of the system by comparing the first pressure and the second pressure.

摘要： A releasable packer device and a method for selectively releasing a packer assembly from a set position in a wellbore. A packer assembly is described that incorporates a split body lock ring that is in ratcheting engagement with a central mandrel to secure the packer elements in a set position. In addition, there is a mechanical means for releasing the body lock ring from its locking position to an unlocked position. The body lock ring is released by radially expanding the ring by urging an axially-movable release sub with a releasing portion into contact with the body lock ring to unseat the ratcheting mechanism that retains the packer assembly in its set position.

摘要： Embodiments described herein provide a downhole tool (e.g., a retrievable bridge plug) that includes a sealing device and a load retention/equalization mechanism. The sealing device includes an elastomer seal component and an expansion device configured to radially expand outwardly to compress the elastomer seal component against a wellbore casing within which the downhole tool is located. The sealing device further includes lower and upper support barriersconfigured to radially expand outwardly against the wellbore. The sealing device also includes a seal energizing spring configured to maintain an initial setting force of the elastomer seal component against the wellbore casing. The load retention/equalization mechanism includes a spool/inflation valve configured to direct fluid into an internal volume to inflate the elastomer seal component radially outwardly based on a differential pressure between a first volume uphole relative to the downhole tool and a second volume downhole relative to the downhole tool.

摘要： A coiled adaptive seat (10) is held to a smaller diameter for delivery with a tool (40) that can feature a locating lug (42) for desired alignment of the seat with an intended groove (16) in the inner wall of a tubular. The release tool retracts a cover (48) from the seat allowing its diameter to increase as it enters a groove. Alternatively, the adaptive seat is released near the groove and pushed axially in the string to the groove for fixation. Once in the groove the inside diameter of the string is a support for a blocking object so that sequential treatment of parts of a zone can be accomplished. The blocking object is removed with pressure, dissolving, milling or disintegration leaving a narrow ledge in the tubular bore from the seat that can simply be left in place or milled as well. An E4#10 from Baker Hughes is modified for adaptive seat delivery.
摘要翻译：（10）被保持到较小的直径以用于可以具有定位凸耳（42）的工具（40）进行输送，用于期望的座位与预期的凹槽（16）的对准）在管状物的内壁中。释放工具从座上缩回盖子（48），使其直径在进入凹槽时增加。或者，适应性座位在凹槽附近被释放，并且被轴向地推动到凹槽中以固定。一旦进入凹槽，绳的内径就成为阻挡物体的支撑物，从而可以实现区域部分的连续处理。通过压力，溶解，碾磨或分解将阻塞物体移除，在座位的管状孔中留下狭窄的突出部分，其可以简单地留在原位或研磨。来自贝克休斯的E4＃10被修改用于自适应座椅交付。
