    摘要: System, apparatus, and method for delivering grease to process valve(s). The system generally includes a grease cylinder to which grease is delivered, a piston, an actuator, and a first process valve. The piston extends at least partially within the grease cylinder. The actuator strokes the piston within the grease cylinder to meter a first amount of the delivered grease to the first process valve. The actuator comprises a power cylinder within which the piston extends. The piston comprises a head portion slidably disposed in the power cylinder and dividing the power cylinder into first and second chambers. The head portion has a first cross-sectional area. The piston includes another portion contacting the grease in the grease cylinder and having a second cross-sectional area smaller than the first cross-sectional area. The actuator may also meter a second amount of the delivered grease to a second process valve.

    摘要: A method, apparatus, and system according to which a swap adapter is connected to a swap station while a discharge manifold is pressurized by at least a first fracturing pump, said discharge manifold being adapted to communicate pressurized fluid to an oil and gas wellbore. The swap adapter is connected to a second fracturing pump via a first suction conduit and a first discharge conduit. The swap station is connected to a suction manifold via a second suction conduit. The swap station is connected to the discharge manifold via a second discharge conduit. After connecting the swap adapter to the swap station, and while the discharge manifold remains pressurized by at least the first fracturing pump: fluid is drawn from the suction manifold using the second fracturing pump; and pressurized fluid is discharged into the discharge manifold using the second fracturing pump.

    摘要: A system and methods according to which a controller communicates control signals to a first frac leg, which includes a wellhead operably associated with a first wellbore, a valve operably coupled to the wellhead, opposite the first wellbore, a frac line operably coupled to the wellhead, and a zipper module operably coupled to the frac line, opposite the wellhead. The first frac leg includes a first sub-controller that receives control signals from the controller. A grease system lubricates the first frac leg and the zipper module. The grease system includes a second sub-controller that receives control signals from the controller. A second frac leg is operably associated with a second wellbore. The second frac leg includes a third sub-controller that receives control signals from the controller. The first, second, and/or third sub-controllers may receive control signals from the controller via a communication bus.

    摘要: Methods and apparatus according to which a first valve is opened, or kept open, the first valve being part of a wellhead including a flow component above the first valve. The method may further include detecting a state of the first valve and, in response to detecting the state of the first valve, metering an amount of grease to the first valve. In addition, or instead, the method may further include opening, or keeping open, a second valve, the second valve being operably coupled to the wellhead and positioned above the flow component, and, after opening, or keeping open, each of the first and second valves, detecting whether the second valve is open or closed, in response to detecting that the second valve is open, preventing the first valve from being closed, and in response to detecting that the second valve is closed, allowing the first valve to be closed.
