  • Patent number: 11905777
    Abstract: An agitator deployable in a wellbore includes a housing including a central axis and a central passage, a valve including a first valve body having a first contact face and a second valve body permitted to rotate relative to the first valve body and having a second contact face configured to contact the first contact face, a first valve adapter including a first receptacle which receives at least a portion of the first valve body to couple the first valve adapter to the first valve body, and a flexible valve configured to permit the first valve body to flex relative to the first valve adapter whereby an angular misalignment may form between a central axis of the first valve body and a central axis of the first valve adapter.

  • Patent number: 9981362
    Abstract: A method for leaching a PCD table for a cutter element includes (a) positioning a PCD table within a leaching chamber. The method also includes (b) submerging the PCD table in an acid within the leaching chamber. In addition, the method includes (c) sealing the leaching chamber. Further, the method includes (d) increasing the pressure within the leaching chamber to a pressure greater than or equal to 20,000 psi after (c).

  • Patent number: 9598923
    Abstract: A downhole tool comprises a housing having a longitudinal bore and an agitator assembly disposed within the longitudinal bore of the housing. A removable component is disposed within the longitudinal bore and can be removed from the housing so as to at least partially open the longitudinal bore.

  • Patent number: 9269199
    Abstract: A location of a downhole asset relative to a first environment may be tracked. The configuration information for the downhole asset is acquired, where the configuration information includes a measurement of one or more forces applied to the downhole asset during assembly of the downhole asset in the first environment. A service life of the downhole asset is determined from the configuration information. One or more parameters related to usage of the downhole environment in a second environment are measured. A remainder of the service life of the downhole asset is determined by reducing the service life by an amount proportional to usage of the downhole asset as indicated by the measurement related to usage of the downhole asset. The remaining service life may be used to automatically initiate an order for new parts.

  • Publication number: 20070044976
    Abstract: An improved ram inner seal assembly used in ram-type BOPs is disclosed. The disclosed invention provides an inner guide seal assembly that comprises a specially shaped guide body and a separate sealing element. When the ram-type BOP is closed, two opposing rams move toward one another, and the inner guide seal assembly guides a wireline (or other tubular) toward the center of the vertical bore through the BOP. The inner guide seal assembly's proximity to the ram body's centerline axis helps ensure that a positive seal is formed and that no damage occurs to the device in the central bore of the BOP. The separate, specially-shaped sealing element can be easily inserted into and removed from the guide body of the inner guide seal assembly for easy replacement.

  • Publication number: 20060113501
    Abstract: An improved shear/seal ram assembly used in ram-type BOPs is disclosed. The disclosed invention is a unique shear/seal ram assembly in which rail seal actuators attached to or integrally formed in a planar surface of one shear blade mate with and slide within corresponding rail guide grooves formed in a planar surface of a second shear blade. As the shear blades move over each other, the rail seal actuators slide within the rail guide grooves, eventually coming into contact with a seal actuator plate of a unique blade-to-blade seal assembly placed within a shear blade seal groove. Continued movement of the shear blades over each other causes the rail seal actuators to compress, or “energize,” the blade-to-blade seal of the blade-to-blade seal assembly, thereby providing a pressure tight seal between the shear blade assemblies.
