摘要： A string to be expanded is run in with a running string that supports a swage assembly. The running string is secured to the existing tubular and the top of the string to be expanded is sealed around the supported running string. The pressure applied to the annular space above the seal drives the liner over the swage. A cement shoe is affixed to the lower end of the string that is expanded after becoming detached from the running string assembly. When the expanded liner bottoms on a support, generally the hole bottom, the cement is delivered through the shoe and the expansion of the top of the string into a recess of the string above continues. The swage assembly with the seal and the anchor are then recovered as the running string is removed during the process of expanding the top of the expanded string into the lower end recess of the existing string already in the wellbore.

摘要： The tubular string to be expanded is run in on a running string. The swage assembly has a seal from the running string to the existing tubular and the top of the tubular string to be expanded also has a similar seal against the existing tubular. Annulus pressure around the running string drives the swage assembly to support the expanded tubular to the existing tubular and to continue expansion to the end of the tubular. Cementing then takes place followed by reconfiguring the swage assembly to engage the liner hanger seal with the result being a monobore connection in a single trip including the cementing.

摘要： Methods for forming a wellbore may include placing an upper section of inside a lower section of a parent liner; positioning an upper sealing member and a lower sealing member in the wellbore to form a pressure chamber, and expanding the second liner using the pressure chamber. The sealing members move axially relative to one another and the second liner has an inner bore that is hydraulically isolated from the pressure chamber. A related apparatus may include upper and lower sealing members that cooperate to form a pressure chamber that is hydraulically isolated from an inner bore of the second liner. A work string may include the sealing members, a connector that extends through the pressure chamber and the second liner; and an expander. The expander expands the second liner in response to the axial separation of the sealing members.

摘要： The seal has a base ring that expands with the underlying supporting tubular. Extending from the base ring is a pleated structure with segments folded over each other so that the run in shape is small and up against the supporting tubular for run in. The pleated segments can have internal stiffeners that also add a bias radially outwardly when the structure is freed to move in that direction. A retaining band keeps the assembly retracted until tubular expansion defeats the band to allow the unitary structure to move out radially to the wellbore or surrounding tubular. The pleated portion unfolds and spans outwardly from the base ring to retain pressure differential in one direction while allowing fluid flow in the opposite direction. The assembly can be attached to a swage device so that pressure from above into the set seal can drive one or more swage members to expand a tubular.

摘要： 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.
摘要翻译：

一个自我包含的地下工具可以在定时器控制的自动设定模式下运行到所需位置。如果在将工具及时移动到所需位置时出现问题，则可以在工具启动之前将由永久磁铁或电磁铁产生的磁场施加在工具上以停止计时器。一旦工具随后被定位在所需的位置，就可以在工具附近带来另一个磁场来设置它。或者，可以将工具运行到所需的位置而不用定时器激活，然后可以将磁场带到工具来设置它。可以用电缆将磁场降低到工具上，或者可以将其放下或泵送通过工具以启动工具。可选地，该场可以从最终落座于座椅的物体内产生，以提供使用油管压力设置工具的备用方式。

摘要： A communication system for sequential operation of subterranean tools involves flow based signals that are picked up with an acoustic receiver at a master controller, which then signals one or more slave controllers that operate tools and communicate back to the master controller that the subject tool has been operated. Sensors associated with the control system gather data downloaded when the master controller is pulled out of the hole. The system can be used to set a liner hanger and release a running tool and communicate that the liner hanger and running tool has activated. This can be confirmed with setting down weight and noting the running string going from tension to compression with a load cell or by translating the running string within the hole. The liner top packer can be set with a flow based signal to the master controller which is then removed with the running string.

摘要： A setting assembly for a packer seal features a series of peripherally mounted rod pistons that abut the seal to be set by advancing the seal relative to a tapered surface. When parts of the seal engage an inner tubular wall before other parts of the seal the continuation of application of hydraulic pressure to the pistons moves parts of the seal that have yet to make contact with the tubular wall further relative to the ramp so that plastic deformation of the seal assembly can occur to allow portions thereof to move radially further outwardly to seal in the region where the radius of the tubular is enlarged. When hydraulic pressure is applied to the pistons in an opposite direction a lock mechanism is defeated and the c-ring or scroll reverts to a smaller shape optionally aided by a garter spring so that the packer can be selectively retrieved.
