Sealing element
This disclosure may generally relate to additive manufacturing operations and, more particularly, to systems and methods for three dimensional (3D) printing a sealing element. Specifically, examples of the present disclosure may be implemented to manufacture a sealing element which may be disposed in a wellbore to seal off a portion of a well.
Methods and Apparatus for providing a plug activated by cup and untethered object
A plug assembly includes an expandable assembly, a locking ring and a cup. The expandable assembly is adapted to be deformed radially over the locking ring and the cup. The locking ring has a stopping inner surface. The plug assembly is used with one or more untethered objects, the untethered objects having an outer surface adapted to couple with the cup, and the cup having an outer surface adapted to couple with the stopping inner surface of the locking ring. The combination of cup and untethered objects is also adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.
ELECTRIC SUBMERSIBLE PUMP COMPLETION WITH WET-MATE RECEPTACLE, ELECTRICAL COUPLING (STINGER), AND HYDRAULIC ANCHOR
A system includes an upper section, having a first lateral end. The upper section has upper production tubing configured to be a conduit for production fluids, an upper electrical cable configured to transmit electricity, and a sub-surface safety valve fixed to the upper production tubing. The system further includes a lower section having a second lateral end, lower production tubing configured to be a conduit for the production fluids, a lower electrical cable configured to transmit electricity, an electric submersible pump assembly, and an anchor configured to hold the lower section within the casing string. A stinger assembly is fixed to the first lateral end of the upper section, and a stinger receptacle is fixed to the second lateral end of the lower section. The stinger receptacle is configured to receive the stinger assembly and create an electrical connection between the upper section and the lower section.
Fluid flow control during well treatment
A method of treating a subterranean well can include positioning a flow restrictor in a wellbore that penetrates an interval of an earth formation, displacing the flow restrictor along the wellbore away from a surface of the well, preventing longitudinal displacement of the flow restrictor in the wellbore, introducing flow into a first section of the interval from a section of the wellbore between the flow restrictor and the surface, blocking the flow from the wellbore section into the first interval section, permitting longitudinal displacement of the flow restrictor in the wellbore, and displacing the flow restrictor along the wellbore away from the surface of the well, thereby permitting unrestricted flow from the wellbore section into a second section of the interval. The second interval section is farther along the wellbore from the surface than the first interval section.
Liner hanger with enhanced locking assembly
A liner hanger having one: or more enhanced Socking assemblies is provided. The liner hanger includes a liner hanger body, lower slips, upper slips, a packer cone, and a seal that seals an annulus between the liner hanger and an outer casing, The one or more enhanced locking assemblies may include: a packer cone locking assembly that prevents all components of the liner hanger from actuating until it is unlocked; a slips locking assembly that prevents the lower slips from being actuated until it is unlocked; guide rails that prevent. the lower slips and/or the upper slips from being wedged in a radially outward direction during run in; and a floating cone locking assembly that releases the packer cone from being coupled to a spacer of the liner hanger when it is unlocked.
Wellbore isolation devices with degradable non-metallic components
Wellbore isolation devices, methods of use, and downhole tools and systems comprising the wellbore isolation devices. A wellbore isolation device comprises a component selected from the group consisting of a mandrel, a packer element, a sealing ball, a wedge, a slip, a mule shoe, a wiper element, a wiper body, and any combination thereof; wherein the component comprises a degradable non-metallic material that degrades upon exposure to a wellbore environment; and wherein the degradable non-metallic material is a composite material comprising a non-epoxy matrix material and a reinforcing material.
Plug for oil field service work and method of production
Plugs for use in hydrocarbon recovery operations having lower and upper anchor slip assemblies with individual anchors, upper and lower elements, a shoe and tubular mandrel.
Flapper on frac plug
Zonal isolation devices, systems, and methods for use are provided. In some embodiments, the zonal isolation device comprises a tubular body having a fluid communication pathway formed along a longitudinal axis comprising: a sealing element comprising a deformable material and an inner bore forming at least a portion of the fluid communication pathway; a support ring disposed within the bore of the sealing element; a rotatable sealing component coupled to the support ring; a wedge engaged with a downhole end of the sealing element; and an anchoring assembly engaged with the wedge. In certain embodiments, the tubular body further comprises an end element adjacent the anchoring assembly.
Mechanical support ring for elastomer seal
A support ring prevents an elastomer seal from extruding. The support ring is expanded and supports the expanded seal, preventing the elastomer seal failing due to extrusion.
Downhole tool with bottom composite slip
A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 when the bottom slip is in an unset position.
