Methods and systems for a frac plug
An outer diameter of a mandrel with a recess to accommodate lower slips with a larger thickness, a sealing element with a concave outer diameter to control a pressure differential caused by a Bernoulli Effect across the sealing element, and a disc that is selectively secured to a housing via a removable shear pin, wherein shear pins with different pressure ratings may be inserted into the housing.
Objects and tools for use in hydraulic fracturing and methods of manufacturing same
Embodiments disclosed herein include dissolvable and intentionally degradable objects that are useful for hydraulic fracking operations. Such objects are at least in part manufactured using materials that are soluble in certain fluids including water. The dissolvable and intentionally degradable fracking objects can be manufactured from one or more materials, including composite materials. In one embodiment, dissolvable fracking objects are manufactured from ceramic materials that are soluble in fluids such as water. Such dissolvable fracking objects include fracking balls and plugs. These fracking balls and plugs are arranged to seal a well for a predetermined period of time and dissolve over that predetermined period of time until the well is no longer sealed. In another embodiment, tools generally useful in fracking operations are manufactured to have desirable elastomeric properties. Such tools can be manufactured from a combination of materials that are soluble in fluids and generally dispersible in fluids.

Well packers
A packer for wells can include a body having a tubular shape, a sealing element having an upward end and a downward end and disposed around the body. The packer also includes a first prop upward of the sealing element, and a second prop downward of the sealing element. The first prop is configured to wedge under the upward end of the sealing element and the second prop is configured to wedge under the downward end of the sealing element to push the sealing element outward at both the upward end and the downward end.
Backup rings for downhole bridge plug sealing element systems
Backup rings for a sealing element system for a downhole bridge plug assembly may include a circumferentially-expandable backup ring body having an engaging ring surface. A beveled ring surface may extend from the engaging ring surface. An interior ring surface may extend from the beveled ring surface to the engaging ring surface. A ring opening may be formed by the beveled ring surface. A plurality of spiral ring slots may extend through the backup ring body from the engaging ring surface to the beveled ring surface. A plurality of expandable ring portions may extend between the plurality of spiral ring slots. An at least partially circumferentially-expanding ring sleeve may extend from the backup ring body. In some embodiments, an outer width or diameter of the ring sleeve may correspond to an outer width or diameter of the backup ring body. The ring sleeve may include a ring sleeve wall extending from the interior ring surface of the backup ring body. A sleeve interior may be formed by the ring sleeve wall. A plurality of sleeve slots may extend through the ring sleeve wall. The plurality of sleeve slots may communicate with the plurality of spiral ring slots, respectively, in the backup ring body. A plurality of expandable sleeve portions may extend between the plurality of sleeve slots. The plurality of expandable sleeve portions may extend from the plurality of expandable ring portions of the backup ring body.
Artificial lift assembly
An artificial lift assembly and method relating thereto is designed to prevent inadvertent electrical discharge caused by fluids flowing through an electrical submersible pumping system, which is part of the assembly. The assembly uses a rupture disc to prevent fluid flow during introduction of the assembly into a wellbore and a dart and sleeve to prevent fluid flow during removal of the assembly from the wellbore.

Method and apparatus for sealing a side pocket mandrel
A method for sealing a side pocket mandrel and hydraulic tube includes moving a sealant dispenser into a pocket of the side pocket mandrel from within a well tubing. The sealant dispenser has an upper seal and a lower seal spaced apart therefrom; the seals are sealingly engaged with the pocket. A space between the upper seal and the lower seal is in fluid communication with at least one port in the pocket. A curable sealant is moved from the sealant dispenser into the pocket and into the tube. Either the sealant is allowed to cure or the sealant dispenser is unlatched from a running tool used to move the sealant dispenser into the pocket.
