摘要： Embodiments presented provide for an apparatus that provides a dislodgable plug seat that is used to capture a cement wiper plug for wellbore cementing operations. The apparatus further includes a collar having a ball seat and a closing sleeve configured to be shifted from an open position to a closed position. In the open position, a fluid pathway between an interior volume and a wellbore annulus is unblocked, and in the closed position the fluid pathway is blocked. A split ring is shiftable with the closing sleeve between a retained configuration when the closing sleeve is in the open position and an expanded configuration when the closing sleeve is in the closed position. The split ring holds the dislodgable plug seat in place within the body in the retained configuration and releases the dislodgable plug seat in the expanded configuration.

摘要： An interventionless stimulation and production system includes a housing and a stimulation sleeve. The stimulation sleeve includes a first diverter seat, and a second diverter seat initially having a smaller diameter, where the first diverter seat is configured to permit a first diverter to pass through the first diverter seat and prevent a second diverter having a larger diameter from passing through the first diverter seat, the second diverter seat is initially configured to prevent the first diverter from passing through the second diverter seat, and landing the first diverter onto the second diverter seat shifts the stimulation sleeve from a first position to a second position to initiate a stimulation operation. The stimulation also includes a production sleeve that is initially in a closed position, where the production sleeve is configured to shift to an open position after the second diverter lands on the first diverter seat.

摘要： A flow control configuration including a housing, and a port sleeve disposed therein having a first positively restrained position, a second positively restrained position, and a third positively restrained position within the housing. The configuration includes a first releaser associated with the first position, and a second releaser associated with the second position. A method for controlling flow including landing a first object on a seat in the port sleeve, shifting the port sleeve to the second position thereby aligning a port and an opening. The method further includes landing a second object on a second object seat within the housing and shifting the port sleeve to the third position. A borehole system includes the flow control configuration disposed within or as a part of a string in a borehole.

摘要： Aspects of the present disclosure relate to a casing string comprising a buoyant mandrel and one or more dissolvable plugs, and methods of conducting wellbore operations using the casing string. The casing string may have an upper mandrel comprising a rupture disk. A slotted mandrel may be coupled to a lower end of the upper mandrel and comprise a plug disposed in a port of the slotted mandrel. A casing shoe may be coupled to a lower end of the slotted mandrel and comprise a check valve assembly. A gas filled chamber may be formed between the rupture disk and the check valve assembly. The plug may be configured to dissolve after a predetermined amount of time when in contact with a wellbore fluid.

摘要： A rupture disk. The disk includes a body having an inside surface defining a hollow therein and a fluid port disposed to make fluid connection between the hollow and a fluid pressure source. A method for operating a wellbore includes applying pressure though the port of a disk, and rupturing the disk with the applied pressure.

摘要： An electronic trigger system includes a longitudinal housing including detection, electronics, and actuation sections disposed therein. The detection section includes a pressure sensor for receiving a predetermined pressure signal, and an electronic control board including at least one battery is disposed in the electronics section. The actuation section includes a prefill chamber, a setting piston disposed in the prefill chamber, an actuation device, an atmospheric chamber, and a pressure port. A predetermined amount of prefilled fluid at hydrostatic pressure is trapped between the setting piston and the actuation device in the prefill chamber. The actuation device isolates the prefilled fluid at hydrostatic pressure in the prefill chamber from the atmospheric chamber. Actuation occurs when, upon receipt of the predetermined pressure signal by the pressure sensor, the electronic control board transmits power to the actuation device, causing the prefilled fluid to flow through the actuation device and into the atmospheric chamber.

摘要： Assemblies and methods are provided for a sleeve assembly for controlling communication with a downhole formation having a sleeve housing with one or more flow ports slidably retaining a sleeve, the sleeve having one or more treatment ports. The sleeve is configured to slide between an uphole closed position, in which the one or more flow ports are blocked by the sleeve, and a downhole open position in which the one or more flow ports are at least partially aligned with the one or more treatment ports. The one or more treatment ports may have inset members.

摘要： A system and method for injecting bailer content utilizing a dump bailer having an elongated, flexible bailer receptacle secured between a head assembly and an injection assembly. Disposed within the dump bailer are first and second piston assemblies, each of which includes a piston having a central fluid passage with a pressure actuated flow control mechanism in the form of a rupture disk disposed along the fluid passage of the piston. An electric, positive displacement pump within the head assembly draws wellbore fluid into the dump bailer assembly to drive the first piston assembly towards the second piston assembly so as to release bailer content into a wellbore. The elongated flexible bailer receptacle may be a hose stored on a bailer receptacle reel, which hose may be paid out by the reel to a length that corresponds with a volume of bailer content to be released into the wellbore.

摘要： A downhole tool can be used as a fill valve to circulate a fluid, such as a spacer fluid, through the tool. The tool can include a top and bottom flapper valve and an inner and outer sliding sleeve. The sliding sleeves can be shifted together to allow the top flapper valve to close. Continued shifting of the inner sleeve can cause the bottom flapper valve to close. A cementing operation can then be performed through the tool. Sealing elements can be located between the outside of the inner sleeve and inside of the outer sleeve. Sealing elements can also be located between the outside of the outer sleeve and the inside of a tool mandrel. The sealing elements can prevent debris from becoming lodged within the tool.

摘要： A downhole sub has a body defined by a wall extending in an axial direction from a first end to a second end. An inner surface of the wall defines a flow path through the downhole sub and an outer surface of the wall defines an outer diameter of the downhole sub. A compartment extends from the outer surface into the wall to having a depth less than a thickness of the wall. A housing may be removably fixed in the compartment. One or more mobile devices may be disposed in the housing. Each of the one or more mobile devices includes a sensor encapsulated in a protective material. A control element may block an opening of the housing, the control element is made of a dissolvable material configured to dissolve at a predetermined depth in a wellbore and release the one or more mobile devices into the wellbore.
