A sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore. The sealing assembly is configured to be actuatable to extend sealing elements between the tubular string and an inner surface of the casing to form a fluid seal between the tubular element and the inner surface of the casing.

Sealing assembly for wellbore operations

A method for sealing a borehole, that includes lowering a plug into the borehole, where the plug includes a sealing element, a reservoir that includes a liquid, and a one-way valve connected to the reservoir, causing the sealing element to undergo sealing element expansion, where the sealing element expansion causes the sealing element to make circumferential contact with a casing of the borehole, and where the sealing element expansion causes the sealing element to create a void.

Constantly adaptive void elimination system

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.

Downhole apparatus with a valve arrangement

A method of operating a valve arrangement of a downhole apparatus (that includes a tubular body having first and second ports in a wall thereof) comprising 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 valve arrangement includes a valve member including a first port, the first port associated with the first port of the tubular body, and a second port associated with the second port of the tubular body, wherein the valve arrangement comprises a further retaining member. The method includes operating the 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 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 being 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; 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; and 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.

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 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 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 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.

The present invention relates to a downhole apparatus and a valve arrangement for a downhole apparatus having a tubular body having first and second ports in a wall thereof; and a method of operating a valve arrangement of a downhole apparatus. The valve arrangement has at least one locked configuration and the first port provides fluid communication with a tool or a device which is a sand control element having at least one fluid deformable device. The present invention also provides a method of setting a sand control completion, extending the sand control filter element thereof to a wellbore surface and isolating the reservoir from an upper portion of the wellbore.

There is provided a sandscreen joint () capable of providing zonal isolation. The ends of the portion of the () are capable of extension on activation of the sandscreen (), including transition areas (), which are coated with an elastomer sleeve (). On activation of the sandscreen (), the sleeve () is pushed out into contact with the bore wall and serves to isolate the zone on one side of the activated sleeve () from the zone on the other side of the sleeve (). Thus, the provision of the sleeve () on the activated sandscreen () may prevent fluid from flowing axially along the bore between the bore wall and sandscreen. This may serve to protect the weave at the transition area (), preventing axial flow through the transition areas ().
