A method of pumping an oilfield fluid from a well surface to a wellbore is provided that includes providing a clean stream; operating one or more clean pumps to pump the clean stream from the well surface to the wellbore; providing a dirty stream including a solid material disposed in a fluid carrier; and operating one or more dirty pumps to pump the dirty stream from the well surface to the wellbore, wherein the clean stream and the dirty stream together form said oilfield fluid.

Split stream oilfield pumping systems

An assembly that is usable with a well includes a base pipe, a shroud that is disposed radially outside of the base pipe and tubes. The tubes are disposed radially outside of the base pipe and are radially inside the shroud. The tubes longitudinally extend along the base pipe and radially expand to radially expand the shroud in response to pressurization of the tubes.

Screen assembly

A completions assembly that includes an extendable and retractable shifting tool at a lower end of an upper completion. Outfitted with this type of tool, the upper completion may be sealably landed out at an installed lower completion without prematurely opening an isolation valve that ensures well control thereat. Rather, the full completions assembly may be finished out and the valve later opened by extending of the shifting tool from the upper completion toward the isolation valve at the lower completion. Once more, this type of well control is achieved through use of hydraulic lines that are dedicated to the upper completion even though the isolation valve is located therebelow. As a result, the extended use of hydraulic couplings and other complex or wear-prone well control architecture may be largely avoided.

Completions assembly with extendable shifting tool

The current application discloses various embodiments where a portion of a fluid end pump body is made of a first material the other parts of the pump body are made of a second material where the first material is a material having better resistance to fatigue and the second material used is a material of less quality and cheaper than the first material.

Precompression effect in pump body

A pump assembly having a power end and a fluid end, wherein the fluid end includes a plurality of pump bodies connected side by side between opposing end plates with a plurality of fasteners tightened to compress the pump bodies between the end plates. The power end and at least one of the plurality of pump bodies being connected together by a tie rod having a rod portion and a sleeve portion, wherein the sleeve portion surrounds the rod portion and abuts the power end at an end and at least one of the pump bodies of the fluid end at an opposite end.

Pump assembly

A multiple activation-device launching system for a cementing head comprises a launcher body comprising at least one launching chamber and a device chamber, the launching chamber sized to receive one or more activation devices therein, the launching chamber in fluid communication with a power source for launching the activation device into the device chamber. The launching system may further comprise a pressure sensor, a pressure-relief device or a flow-measurement device, or combinations thereof.

Multiple activation-device launcher for a cementing head

An embodiment of a method of operating at least two pressure vessels to inject a particulate slurry into a high-pressure line, comprises a first operating cycle comprising: isolating a pressure vessel from the high-pressure line, introducing, under low-pressure conditions, particulate solids into the pressure vessel through a particulate solids inlet aperture, a second operating cycle comprising: providing high-pressure flow into the pressure vessel, and providing a high-pressure slurry flow from the pressure vessel into the high-pressure line. The method further comprises causing a pressure vessel to operate in the first operating cycle while operating a pressure vessel in the second operating cycle, and synchronizing switching a first vessel from the first operating to a second operating cycle and switching a second vessel from the second operating cycle to the first operating cycle such that at least one of the vessels is operating in the second operating cycle.

Apparatus and method for oilfield material delivery

An apparatus for use in launching cement plugs in a well cementing operation comprises a cylinder, a piston slideably received in the bore of the cylinder and an actuator extending from the piston through the cylinder. The actuator is operable by the piston for launching plugs from the apparatus into the well. A resilient damper cartridge is slideably mounted on the actuator in the cylinder so as to be contactable by the piston. A series of frangible pins is located in the cylinder wall so as to provide temporary limits to the movement of the cartridge in the cylinder as the piston slides along the cylinder.

Damper cartridge for launching plugs in cementing operations

An optical fiber tape assembly for attaching an optical fiber to the surface of a pipe comprising; at least one optical fiber; and a tape having an attachment means to enable attachment of the tape to the pipe; wherein the optical fiber runs longitudinal along the tape and is integral with the tape.

Fibre optic tape assembly

An apparatus for installing cement plugs into a well, comprising a protective sleeve having one end adapted to be attached to the end of a drill pipe and arranged to carry a cementing plug around its outer surface such that a dart passing through the drill pipe can pass through the sleeve and engage only on formations on the plug to withdraw it from the end of the sleeve.

Apparatus and methods for deploying cementing plugs

A pump assembly and maintenance system and method. An inventory of pump components has an identifier to track the pump component and a sensor to gather operating data associated with the pump component. A population of pumps is assembled from the pump components. The operating data are correlated with the pump components based on the identifiers in a network-accessible database. The pump components can include interchangeable pump body modules that are separately tracked, whereby the pumps can be repaired by removing and replacing the interchangeable pump body modules.

A mechanism for pressurized delivery of material into a well without exposure to a high pressure pump. The mechanism may include material delivery equipment that is coupled to the high pressure pump or other pressure inducing equipment through a material carrier that intersects a fluid line from the pump. The material carrier may include chambers that are reciprocated or rotated between positions that are isolated from the fluid line and in communication with the fluid line. While isolated from the fluid line, the chambers may be filled with oilfield material which may then be delivered to the fluid line when positioned in communication therewith. In this manner, a supply of the oilfield material may be retained in a substantially isolated state relative to the pump and components thereof which may be susceptible to damage from exposure to the oilfield material.
