Publication number: 20240018842Abstract: A hydrocarbon extraction system that includes an erosion control system. The erosion control system includes a housing defining a first inlet, a second inlet, and an outlet. The housing receives and directs a flow of a particulate laden fluid between the first inlet and the outlet. A conduit rests within the housing. The conduit changes a direction of the particulate laden fluid and reduces erosion of the housing. The conduit is inserted into the housing through the second inlet. The conduit defines a plurality of apertures between an exterior surface and an interior surface of the conduit. The apertures direct the fluid into a conduit cavity. The conduit guides the fluid entering the conduit cavity to the outlet. The erosion control system excludes a plug and/or a sleeve around or in the conduit.Type: ApplicationFiled: August 8, 2023Publication date: January 18, 2024Inventors: Stuart Robinson, Jerry Martino, Michael Krejci, Abinesh Gnanavelu

Publication number: 20230031920Abstract: A seat assembly for a choke valve assembly includes a housing having an internal passage, in which the housing is formed from a non-superhard material. The seat assembly also includes a seat disposed within the internal passage of the housing. The seat is configured to engage a needle of the choke valve assembly while the choke valve assembly is in a closed state, and the seat is formed from a first superhard material. In addition, the seat assembly includes an annular insert disposed within the internal passage of the housing downstream from the seat. The annular insert is formed from a second superhard material, and a maximum cross-sectional area of the seat along a longitudinal axis of the seat assembly is greater than a maximum cross-sectional area of the annular insert along the longitudinal axis.Type: ApplicationFiled: January 13, 2021Publication date: February 2, 2023Inventors: Declan Elliott, Scott Dahlgren, Edmund Peter McHugh, Abinesh Gnanavelu, Jerry Allen Martino, David C.
