Abstract: A subterranean tool that is self contained for actuation can be run into a desired location on an automatic set mode controlled by a timer. If a problem develops in getting the tool to the desired location in time a magnetic field created by permanent or electro-magnets can be brought to bear on the tool to stop the timer before the tool actuates. Once the tool is subsequently positioned at the desired location another magnetic field can be brought to bear near the tool to set it. Alternatively, the tool can be run to the desired location without activation with the timer and then the magnetic field can be brought to the tool to set it. The magnetic field can be lowered to the tool with wireline or can be dropped or pumped past the tool to actuate the tool. Optionally the field can be generated from within an object that ultimately lands on a seat to provide a backup way to set the tool using tubing pressure.

Abstract translation: 可自动装载用于致动的地下工具可以在由定时器控制的自动设定模式下运行到期望的位置。 如果工具在时间上到达所需位置时出现问题，则永久磁铁或电磁铁产生的磁场可以在工具启动之前停在定时器上。 一旦工具随后定位在所需位置，可以使工具附近的另一个磁场保持固定。 或者，可以将工具运行到期望的位置，而不用定时器激活，然后磁场可以被带到工具来进行设置。 磁场可以用电缆下降到工具，或者可以通过工具掉落或泵送，以致启动工具。 可选地，该场可以从最终落在座位上的对象内产生，以提供使用管道压力设置工具的备用方式。

Abstract: Downhole tools for anchoring and isolating at least one zone in a wellbore comprise a mandrel having an upper end, a lower end, an outer wall surface, and a longitudinal bore disposed therethrough having an axis. One or more anchors are disposed through the outer wall surface of the mandrel. Each of the anchors has a retracted position and an extended position. An isolation element is disposed along the outer wall surface of the mandrel. The isolation element may cover the anchors or be disposed, above, below, or around the anchors. Engagement of the isolation element with the inner wall surface of the wellbore to isolate at least one zone of the wellbore may be accomplished by piercing the isolation element to permit wellbore fluid to contact a swellable material contained within the isolation element, or by pumping fluid into the isolation element.

Abstract: Apparatuses for restricting fluid flow through a well conduit comprise a tubular member having a seat member disposed within the tubular member for receiving a plug element. One or both of the seat member or the plug element comprise at least one shape-memory material to facilitate the plug element being able to land on the seat and/or to facilitate the plug element to pass through a seat member or other restriction in the tubular member either before or after landing on a seat.
