A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a first valve arrangement comprising a first valve member associated with the first port of the tubular body; and a second valve arrangement comprising a second valve member associated with the second port of the tubular body. The first valve arrangement and the second valve arrangement are configurable to lock in a first configuration with the tubular body, such that the first port is closed and the second port is closed; to lock in a second configuration with the tubular body, such that the first port is open and the second port is closed; and to lock in a third configuration with the tubular body, such that the first port is closed and the second port is open.

A fluid control device includes a filtration component, which has a porous filtration medium. The filtration medium contains a shape memory thermoset material foamed with a polymeric microsphere and a gas-producing chemical foaming agent. The porous filtration medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded to conform to a surface of the borehole.

A method comprises operating a first valve arrangement and a second valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed. The method comprises operating the first valve arrangement and the second valve arrangement from the locked second configuration to a third configuration, in which the first port is closed and the second port is open; and moving the first valve arrangement to a third intermediate configuration between a second intermediate configuration and the third configuration, in which the first valve arrangement is locked, the second valve arrangement is locked and the first and second ports are closed.

A downhole apparatus comprises a tubular body having first and second ports in a wall thereof and a first valve arrangement associated with the first port. The downhole apparatus includes a second valve arrangement associated with the second port and a sand control element operable to move between a first deactivated state to a second activated state, wherein the sand control element is in fluid communication with the first port of the tubular body.

A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a valve member that comprises a first port associated with the first port of the tubular body; and a second port associated with the second port of the tubular body. The valve arrangement is configurable to be locked in a first configuration with the tubular body, such that the first port is closed and the second port is closed. The valve arrangement is configurable to be locked in a second configuration with the tubular body, such that the first port is open and the second port is closed. The valve arrangement is configurable to be locked in a third configuration with the tubular body, such that the first port is closed and the second port is open.

A method of operating a valve arrangement of a downhole apparatus comprising a tubular body having first and second ports in a wall thereof includes operating the valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed, wherein the locked first configuration is an initial configuration of the valve arrangement. The method includes operating the valve arrangement from tile locked second configuration to a third configuration, in which the first port is closed and the second port is open.

A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a first valve arrangement associated with the first port and comprising a first valve; and a second valve arrangement associated with the second port comprising a second valve. The valve arrangement is configurable to lock in a first configuration with the tubular body, such that the first port is closed and the second port is closed; lock in a second configuration with the tubular body, such that the first port is open and the second port is closed; and lock in a third configuration with the tubular body, such that the first port is closed and the second port is open.

A method comprising operating a first valve arrangement and a second valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed, wherein the first valve arrangement comprises one or more locking devices configured to lock a first valve member of the first valve arrangement in place relative to the tubular body. The method comprising operating the first valve arrangement and the second valve arrangement from the locked second configuration to a third configuration, in which the first port is closed and the second port is open.

A method comprises operating a first valve arrangement and a second valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed. The method comprises operating the first valve arrangement and the second valve arrangement from the locked second configuration to a third configuration, in which the first port is closed and the second port is open; and moving the first valve arrangement to a third intermediate configuration between a second intermediate configuration and the third configuration, in which the first valve arrangement is locked, the second valve arrangement is locked and the first and second ports are closed.

A well barrier plug and disconnect system for use during drilling operations in wellbore environments. The system comprises of a liner hanger, valve, and a drilling assembly coupled to a liner hanger running tool. The system is used to performing drilling operations in downhole wellbore environments with high risk of uncontrollable losses, cavernous zones, karst formations, or well control issues. In the event the well is on uncontrollable losses or a well control issue occurs, the liner hanger can be set into the downhole wellbore casing and a valve connected below the liner hanger can be closed creating a barrier plug in the well. Further disconnecting the liner hanger running tool from the liner hanger, valve, and drilling assembly allows retrieval of the upper drilling assembly section from the well.
