Hydraulic Fracturing Device Patents (Class 166/177.5)
  • Patent number: 9719339
    Abstract: A well with existing perforations is re-fractured by positioning isolators at locations offset from the existing perforations and perforating through those isolators. The isolators are part of a bottom hole assembly that can be delivered on coiled or rigid tubing. The initial fractures can be straddled by the isolators with no mandrel openings between them to effectively isolate the existing perforations as new perforations take place through the isolators. The elements of the isolators can have internal gaps to allow for axial shifting after perforation that is thermally induced. The gaps assure remaining alignment with the new perforations despite some axial shifting. The bottom hole assembly can alternatively have an anchor to resist thermally induced forces that can cause axial shifting.

  • Patent number: 9410411
    Abstract: Fractures are induced from lobe shaped inflatable members disposed at different axial locations along a string with frac ports in the circumferential gaps between the lobes. The lobes are inflated by landing a ball on a seat on a sleeve that is initially shifted enough to expose a fill port on each lobe. The lobes are inflated to a pressure that initiates fractures in the formation as the lobes extend. Further raising the pressure induces the sleeve to move a second time to open frac ports. The annulus can be cemented and fracturing can penetrate the cement to further propagate the initiated fractures from lobe inflation. The process is repeated at different levels until the zone of interest is completed. Sensors can relay information by telemetry techniques as to the onset of fractures or other well conditions. The sleeve for the frac ports can be moved in a variety of ways without intervention tools.

  • Patent number: 9243495
    Abstract: A tool for use in initiating a hydraulic fracture in a bore hole comprises an elongate cylindrical bore hole packer structure (11) having an inner longitudinal passage (12), a mid-portion (13) provided with ports (14) extending outwardly from passage (12) to the exterior periphery of the packer structure (11) and expandable circumferential well portions (15A) surrounding the inner longitudinal passage (12) to each side of the mid-portion (13). In use of the tool the circumferential wall portions (15A) can be expanded by injection of hydraulic fracturing fluid into passage 12) and exit of the injected fluid through the ports (14) to produce a pressure difference between the inside of the packer structure and the outside of the packer structure as the fluid passes through the ports (14) such that the hydraulic fluid exiting the packer structure can initiate a fracture.

  • Patent number: 9074453
    Abstract: A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by extendable members that are located behind isolation valves. The extendable members can comprise a biodegradable plug that allows extension of the extendable members by application of pressure. With the plug remained in place, additional pressure can be delivered until at least a portion of the degradable material is pushed onto the surface of the formation. At least a portion of the pushed degradable material provides a seal between the end of the extendable members and the surface of the formation to allow pressure to build until the formation frac gradient is exceeded and the formation is fraced.

  • Publication number: 20150136403
    Abstract: The system and method for hydraulic fracturing includes a downhole tool with a sub, a sleeve, a ball seat support, and a ball seat holder. A ball dropped through the wellbore sits on the ball interface of the ball seat holder. Fluid flowing through the system pushes the ball against the ball interface, causing the ball seat holder to slide through the ball seat support and the ball interface to clamp the ball. A ball matches only a particular ball interface. Additional pressure forms a seal of the ball, the ball seat holder, and the ball seat support and moves the sleeve to slide through the sub and expose the throughbore to the annulus for the fracturing. Contact distributed between the ball, ball interface of the ball seat holder, and ball seat support withstands the temperature and pressure of the fracturing without deformation or failure of the ball.

  • Patent number: 8881821
    Abstract: A well that has a plurality of sliding sleeves used to originally fracture multiple zones with balls of increasing size dropped on balls seats to sequentially open ports for fracturing in a direction toward the well surface is refractured. The method involves using a bottom hole assembly (BHA) that has a fluid motor driven mill that mills out ball seats and has with it a ported sub and a resettable packer. Once the lowermost ball seat is milled out a ball is dropped into the BHA to isolate the fluid motor and open a ported sub below a resettable packer. The dropped ball also enables a collet to latch an open sleeve to give a surface signal that the BHA is located properly for packer deployment so that the refracturing can begin through the coiled tubing string that can support the BHA or in a surrounding annular space.

  • Patent number: 8875790
    Abstract: A method for fracking and completing a well having a well bore through a formation includes packer jack fracking the formation using a packer to form a packer fractured formation moving the packer to seal the packer fractured formation, and hydraulically fracturing the packer fractured formation by injecting a fracking fluid through the packer. These steps can then be repeated through successive intervals of the formation. To complete a new well, a perforated liner can be placed in the well bore to direct the fracking fluid into the packer fractured formation. To complete an existing or a new well having a cemented liner the packer jack fracking step can also be used to break apart the liner and form at least one opening to provide a flow path for the fracking fluid. A system includes a perforated liner and a packer configured to fracture and seal successive intervals.

  • Patent number: 8857516
    Abstract: Systems and methods for fracturing multiple zones in a wellbore. A first port in a first valve assembly can be opened with a shifting tool. A fluid flows through the first port to fracture a first zone, and the first port can be closed with the shifting tool after the first zone has been fractured. A second port can be opened in a second valve assembly with the shifting tool after the first port has been closed, wherein the second valve assembly is positioned below the first valve assembly. The fluid can flow through the second port to fracture a second zone, and the second port can be closed with the shifting tool after the second zone has been fractured.

  • Patent number: 8851178
    Abstract: A method of fracturing a formation while drilling a wellbore. The method includes providing a bottomhole assembly (“BHA”) having a reamer positioned above a pilot hole assembly, connecting the BHA to a drill string, actuating the BHA to drill a first wellbore section with the reamer and to drill a pilot hole with the pilot hole assembly, hydraulically sealing the pilot hole from the first wellbore section, and fracturing the formation proximate the pilot hole.

  • Patent number: 8851179
    Abstract: A process and process line is provided for preparing a friction-reduced hydraulic fracturing fluid at a central location which can be readily transported to an oil or gas well in a formation at a well site, comprising: preparing a mixture of polymer and water at the central location by shearing the polymer in the water in a high shear environment to create the friction-reduced hydraulic fracturing fluid; pumping the friction-reduced hydraulic fracturing fluid through a series of pumps and pipelines to the well site; and injecting the hydraulic fracturing fluid into the oil or gas well at a pressure sufficient to cause fracturing of the formation.

  • Publication number: 20140284058
    Abstract: A pressure response fracture port tool and method for its use reliably provides a noticeable indication at surface to an operator as to when the flow port is opened. The tool includes an outer housing and a sliding sleeve which resides within the outer housing. The outer housing has a first and second set of flow ports. The inner mandrel moves between a first position and a third position to expose the flow ports to the wellbore. The first set of flow ports, with its smaller area relative to the second set of flow ports, creates a noticeable pressure increase or spike that can be observed at surface when exposed to the wellbore. The second set of flow ports creates a noticeable pressure drop when it is exposed to the wellbore.
