Abstract: A release mechanism for use in setting a downhole tool comprises two connectors releasably connected to one other. One of the connectors includes a material having a coefficient of thermal expansion that is different from a material included in the second connector. The difference in the coefficients of thermal expansion causes one of the connectors to expand greater than the other connector when heat is applied to one or both of the connectors. As a result of the greater expansion of one of the connectors, the connectors release from each other. Upon release, an actuator within the downhole tool is permitted to move and cause actuation or setting of the downhole tool.

Abstract: 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.

Abstract: 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.

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: An actuator and method for setting a subterranean tool uses an externally mounted actuator on a tubular string that is operably engaged to the tool to be actuated. At the desired location for actuation a signal is given to a valve assembly. The opening of the valve releases the pressurized compressible fluid against a floating piston. The piston drives viscous fluid ahead of itself through the now open valve that in turn drives an actuating piston whose movement sets the tool. The triggering mechanism to open the valve can be a variety of methods including an acoustic signal, a vibration signal, a change in magnetic field, or elastic deformation of the tubular wall adjacent the valve assembly.

Abstract: A downhole tool for applying a force to a component in a borehole penetrating a subsurface formation includes an acoustic transducer configured to receive an acoustic signal. The tool also includes a spring having a spring force, a spring force retention device defining a perimeter having a gap and in mechanical communication with the component where the spring force retention device being configured to retain the spring force, and a gap member configured to be disposed in the gap. The tool further includes a force generator coupled to the gap member and in operable communication with the acoustic receiver and configured to operate in response to receiving the acoustic signal to withdraw the gap member from the gap to cause the spring force retention device to release the spring force thereby applying the spring force to the component.

Abstract: A system includes a tubular having an interior surface, a longitudinal axis, a flowbore, and a main portion having a first inner diameter. A vibration inducing feature is disposed along the interior surface of the tubular and is immovable with respect to the tubular, and has a second inner diameter within the tubular that is different than the first inner diameter. The feature has a beveled first end surface and a beveled second end surface, the beveled first and second end surfaces longitudinally displaced from each other. The feature is configured to increase turbulence within the flowbore and configured to dissuade a capture of objects passing therethrough. A sensing system includes a sensor arranged to detect vibration within flow passing the vibration inducing feature, and is configured to output a command signal in response to sensed data reaching a threshold value or indicative of a predetermined pattern.

Abstract: A tubular string is advanced with a bottom hole assembly as the hole is drilled and reamed in a desired direction with the aid of directional drilling equipment adjacent the bit. When the advanced tubular forms the desired lap to the existing tubular, the assembly can be configured to cement the tubular and expansion can then be accomplished to fill the annular space and enhance the cement bonding. The expansion equipment can create a bottom bell on the expanded tubular and expand the top end into a bell of the existing tubular so that a monobore is created as the process is repeated with each added string. Numerous variations are contemplated for each single trip including but not limited to the direction of expansion, whether cementing or expansion occurs first, reforming folded tubing in the hole as well as the nature of the expansion tool and pressure control when drilling.
