Patent number: 10247314Abstract: A plug valve including a valve body defining a cavity and a pair of fluid passages intersecting the cavity, the cavity defining a tapered interior surface of the valve body, a plug extending within the cavity, the plug defining an exterior surface and a fluid passage adapted to be substantially aligned with the fluid passages of the valve body, and an insert extending within the cavity and circumferentially about at least a portion of the plug, the insert defining a pair of fluid passages substantially aligned with the fluid passages of the valve body, respectively. In several exemplary embodiments, the plug valve is used in oil or gas operations, such as, for example, the fracturing or gravel packing of a subterranean wellbore, with the plug valve being used to control the flow of fracturing and/or gravel-packing fluids. Exemplary embodiments of methods associated with the plug valve are also described.Type: GrantFiled: January 19, 2018Date of Patent: April 2, 2019Assignee: Tech Energy Products, L.L.C.Inventors: Todd Roberts, Barton Hickie

Patent number: 10156106Abstract: A drilling choke including a choke body defining an internal region, an inlet passage, and an outlet passage, a seat extending within the outlet passage, a nose extending within the internal region and defining a recessed region, a plug extending within the recessed region, and a stem connected to the plug and extending axially therethrough, the stem defining an internal passage. The plug can be engaged with the seat to at least partially restrict fluid flow from the inlet passage to the outlet passage via the internal region. The stem and the plug are together axially moveable in opposing directions relative to the seat to thereby control a backpressure of the fluid flow. In some embodiments, the recessed region of the nose is in fluid communication with the outlet passage of the choke body via the internal passage of the stem to thereby pressure balance the plug.Type: GrantFiled: October 23, 2017Date of Patent: December 18, 2018Assignee: TECH ENERGY PRODUCTS, L.L.C.Inventors: Todd Roberts, Nischit Reddy Kadari, Barton Hickie
