The valve member is a sleeve having a part spherical surface, is rotationally moveable relative to the body to align and misalign the at least one aperture in the valve member with a port in the body. The valve member is actuable to rotate relative to the body in a single direction, and moves from the open position to a closed position and back by rotation in the same sense. The valve also includes a sealing arrangement adapted to provide a metal seal that is biased to seal against the part spherical surface.

Abstract: A protection sleeve (12) for locking over a seal (72) in a wellbore is described. The sleeve (12) is adapted for releasable engagement to a running tool (14) and has a locking mechanism (28) comprising first and second tubula members and a collet (56) is provided. One tubular member includes a profile adapted to mate with a profile of the seal (72). The sleeve (12) may be located on a work string (14), including a rotary drill string, and the invention also relates to methods of running in, setting, carrying out an intervention operation and retrieving the sleeve in a single run. The invention has particular application in Through Tubing-Rotary Drilling (TTRD).

Abstract: An actuating mechanism for use in a tool such as a plug used in oil and gas wells. The mechanism being operable under pressure in the well bore to set the plug in a first natural closed state for a pressure under a predetermined pressure range; a second closed state wherein the plug is locked closed regardless of the pressure; and a third open state by increasing the pressure to the predetermined pressure range and holding the pressure in the range for a predetermined time. Electronic and mechanical, dual piston, actuating mechanisms are described as is a method of controlling fluid flow in a well bore using the plug and performing a pressure test against the plug.

Abstract: An electronic actuation system for a pressure equalizing device in a downhole apparatus such as a wellbore plug is described. The system includes a pressure sensor for measuring pressure in the wellbore, and means for setting a reference pressure value using a measurement from the pressure sensor. In a method of use, an applied pressure value is determined using a measurement from the pressure sensor and the reference pressure value, and the device is actuated, or opened, when the applied pressure meets a pre-determined condition, such as falling within a pressure window for certain time period. The invention allows natural changes in wellbore pressure to be accounted for when detecting a pressure actuation event.

Abstract: A bag includes a panel having an inner surface and an outer surface and an elongate aperture through the panel. A handle strip having a handle carrying part is disposed adjacent the panel inner surface with the carrying part inserted through the aperture. Extension parts of the handle strip depending from the carrying part are located adjacent the panel inner surface and one or both of the extension parts are folded over and heat sealed to each other and to the inner surface of the bag. The folded extension acts to provide a reinforcing strip and to seal the aperture.

Abstract: A bag structure has a hermetically sealed bag with an outer ply sealed to the bag to define a cavity. The cavity is bounded on one side by a part of the bag and bounded on another side by the outer ply. Perforations are formed through the outer ply to permit passage of gas from the atmosphere into and out of the cavity to reduce unsightly bricking. A one-way valve is formed in the hermetically sealed bag to permit passage of gas from the interior of the bag.
