Patent number: 11293263Abstract: A technique facilitates rapid transitioning of a valve, e.g. a gate valve. According to an embodiment, a system comprises a valve actuator constructed for coupling with a valve to actuate the valve between closed and open positions. Hydraulic actuation fluid may be supplied to the valve actuator under pressure via a hydraulic supply system to enable selective shifting of the valve actuator, and thus the valve, from a closed position to an open position. The system also comprises a dump tank coupled to the valve actuator in a manner to receive hydraulic fluid. In a rapid valve actuation operation, e.g. closing operation, the dump tank receives hydraulic fluid from the valve actuator rather than returning the hydraulic fluid to the hydraulic supply system. This, in turn, enables rapid shifting of the valve actuator and thus rapid shifting of the valve.Type: GrantFiled: January 13, 2020Date of Patent: April 5, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Jermetris McLin, Mark McGilvray, Jr., Jerry Martino, Carl Toups

Patent number: 11280141Abstract: A technique facilitates monitoring fluid phases of a multiphase flow during, for example, well fluid production operations. According to an embodiment, data may be obtained from devices, such as chokes and pressure sensors. This data is then processed to identify phases of the multiphase well fluid flow. The use of data from such well related devices effectively establishes a virtual multiphase flowmeter. However, the output from the virtual multiphase flowmeter may be calibrated periodically by taking measurements from an actual multiphase flowmeter. In some embodiments, the data from a plurality of flow meters having differing physical operating principles may be correlated in a manner to obtain additional parameters related to the multiphase well fluid flow.Type: GrantFiled: July 23, 2019Date of Patent: March 22, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: David Quin, Edmund Peter McHugh

Patent number: 11274751Abstract: Valves having seats and counterseats with various contours are provided. In one embodiment, a valve includes a body and a flow control assembly inside the body. The flow control assembly includes a ball, a seat installed on the ball, and a counterseat. The ball is rotatable between open and closed positions to control flow through the body and the seat and counterseat include mating surfaces that engage when the ball is in the closed position such that the seat seals against the counterseat along the mating surfaces. Further, the mating surface of the counterseat can be a concave surface, the mating surface of the seat can be a convex surface, and at least one of the mating surfaces can have a toroidal contour.Type: GrantFiled: October 9, 2018Date of Patent: March 15, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Brian Roppolo, Alberto Daglio, Barry Pellichino, Clayton Schenk

Patent number: 11261370Abstract: A method of treating a fluid to reduce the level of H2S therein while inhibiting the deposition of scale on surfaces in contact with the fluid, comprising introducing into the fluid a triazine scavenger compound and a terpolymer. The fluid may be liquid or gas and may be petroleum, petroleum product, natural gas, liquefied petroleum gas or other type of oil fraction or refined oil. The triazine scavenger may be e.g. 1,3,5-tri(2-hydroxyethyl)-hexahydro-1, 3, 5-triazine. The terpolymer may comprise a carboxylate/sulphonate/non-ionic terpolymer. When added to a wellbore fluid, it is effective as a scavenger of H2S and also reduces the amount of scale deposition on a surface in contact with the fluid when the fluid comes into contact with or is mixed with a brine. In some aspects, the composition increases the proportion of precipitated solids held in suspension when the fluid is contacted with or mixed with a brine.Type: GrantFiled: September 30, 2015Date of Patent: March 1, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: James McRae, Suguna Gopal, Anand Annamalai

Patent number: 11261978Abstract: An apparatus includes a valve having a hollow body and an inner sealing assembly positioned in the hollow body. The inner sealing assembly includes a piston and can be moved between an open position and a closed position to selectively control flow along a flow path through the valve. The flow path includes a bore of the piston that allows flow through the piston, and pressure within the valve from a fluid in the flow path within the valve biases the inner sealing assembly toward the closed position to stop flow through the valve. Additional systems, devices, and methods are also disclosed.Type: GrantFiled: March 27, 2019Date of Patent: March 1, 2022Assignee: Cameron International CorporationInventors: Jason M. Pivowar, Delbert Vanderford, Moyosore Terebo, Kristin D. Vorderkunz

Patent number: 11255487Abstract: A pretreatment system and method for a floating liquid natural gas (“FLNG”) facility are presented. The inlet natural gas stream flows through a membrane system to remove carbon dioxide and a heat exchanger, producing first and second cooled CO2-depleted non-permeate streams. The first cooled CO2-depleted non-permeate stream is routed to additional pretreatment equipment, while the second cooled CO2-depleted non-permeate stream is routed directly to a LNG train. Alternatively, the inlet natural gas stream may flow through a membrane system to produce a single cooled CO2-depleted non-permeate stream that is routed to the LNG train after sweetening and dehydration. Because the pretreatment system delivers the incoming gas stream to the LNG train at a lower temperature than conventional systems, less energy is needed to convert the gas stream to LNG. In addition, the pretreatment system has a smaller footprint than conventional pretreatment systems.Type: GrantFiled: October 16, 2017Date of Patent: February 22, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Ankur D. Jariwala, Richard D. Peters
