A wellhead port plug assembly having a sensor unit, a plug, a transmitter unit arranged in the sensor unit and comprising a wireless signal transmitter, and a receiver unit arranged on the spool unit and comprising a wireless signal receiver. There is also disclosed a method for installing, removing or replacing a sensor unit located in a port of a wellhead.

Wellhead assembly and method

A downhole plug, has an elongate body, the body having a longitudinal axis; a first seal arranged on an outer surface of the elongate body; and a second seal arranged on the outer surface of the elongate body and spaced longitudinally from the first seal. A production tubing for a petroleum well, includes a pipe, at least one side pocket mandrel, and at least one plug.

Plug and production tubing for a petroleum well

A gas lift valve for use in a hydrocarbon well includes an elongated valve housing including an inlet port for receiving a fluid from an annulus of a hydrocarbon well, and an outlet port for delivering the fluid to a production tubing of the hydrocarbon well, and an elongated, internal valve body, which is movable along a longitudinal, central axis of the valve housing between a first end position and a second end position. In the first end position, a sealing surface of the valve body is in sealing contact with a valve seat surface of the valve housing prohibiting the fluid to flow from the inlet port to the outlet port, and in the second end position the sealing surface is separated from the valve seat surface allowing the fluid to flow from the inlet port to the outlet port. The outlet port is positioned at a terminal end of the valve housing.

Gas lift valve

A wellhead port plug assembly includes a first plug body including connection elements allowing the first plug body to be sealingly and removably mounted in a port of a wellhead of a hydrocarbon well. The plug assembly includes a spool unit displaying an axial through-channel extending between a first end and a second end of the spool unit, which spool unit includes a first flange section arranged at the first end for sealingly mounting the spool unit to the wellhead aligning the through-channel with the port, and a second flange section arranged at the second end; a second plug body including connection elements allowing the second plug body to be sealingly and removably mounted in the through-channel; and a blind flange which is sealingly and removably mounted to the second flange section allowing the second plug body and the first plug body to be removed from the wellhead via the through-channel.

Wellhead port plug assembly

A bellows valve includes a first bellows connected to a first cap member at one end and to a support member at the other end, and a second bellows connected to a second cap member at one end and to said support member at the other end. Respective first and second bellows cavities are thus formed inside each bellows. An orifice is arranged to fluidly interconnect the first and second bellows cavities, and a bellows-internal valve device is arranged to selectively open and close the orifice. The bellows-internal valve device includes first and second resilient members arranged on respective first and second sides of the support member and having respective portions being coupled to respective first and second holding members on the valve device. The bellows valve is useful in injection valves, such as gas lift valves.

Bellows valve and an injection valve

A valve arrangement for controlling the flow of an injection fluid from a well annulus into a hydrocarbon well, includes a valve body being insertable into a side pocket mandrel, an injection fluid valve for controlling the flow of the injection fluid through the valve arrangement and a bellows arrangement including a first pressure member, a second pressure member and at least one bellows element. A control line port is arranged in the valve body for fluid communication with a control line of the well and a control fluid chamber in fluid communication with the control line port comprises a hydraulic control fluid for biasing the injection fluid valve towards the open position.

Valve arrangement and method of operating the same

A valve system for use in a wellbore includes a side pocket mandrel and one or more well tools, where the side pocket mandrel includes an elongated body section provided with a connector at its ends, the elongated body section being provided with a substantially fully open main bore for alignment with the well tubing and an offset side pocket bore. At least one through opening is provided in the side pocket mandrel, leading into the side pocket bore, and at least one through opening is provided in the internal wall, leading into the main bore, where the at least two openings are in fluid communication through the side pocket bore, in which side pocket bore at least two valves are arranged in series to form a double fluid barrier between the main bore and an outside of the pocket mandrel, the at least two valves being independently retrievable through at least one installation opening arranged in the internal wall of the side pocket mandrel.

Valve system

A valve () having at least one flange portion () for securing to a wellhead Christmas tree () for shutting off a pipe outlet () from the wellhead Christmas tree (). At least one of the flange portions () includes integrated devices () for operation of a second unit () mounted outside the valve ().
