Abstract: A downhole tool actuating arrangement includes, a control system configured to communicate pressurized fluid to at least one downhole tool actuatable by pressure changes in the control system, a check valve in operable communication with the control system configured to prevent fluid flow through the check valve in a direction opposite to flow that causes increases in pressure in the control system, and a bleed device. The bleed device is in operable communication with the control system downstream of the check valve, wherein downstream is defined by a direction of flow that causes the check valve to open. The bleed device is configured to allow fluid flow therethrough when pressure on the control system side of the bleed device is greater than on a side opposite the control system.

Abstract: A connector is made up downhole and can connect electrical signal or power circuits. The male component features one or more circumferential bands on the exterior and the female component features like bands on its interior. The bands are preferably covered with removable sleeves until the connection is made up. In the preferred embodiment, the sleeves push each other out of the way as the connection is made up. The bands are preferably cylindrically shaped on their respective supporting connection half to make easy and reliable contact when the connection halves are advanced together without need for rotation to get the desired contact. Seals surround the connected contacts after makeup to keep out well fluids.

Abstract: A cable that delivers power, signals, or information is wet connected downhole. The lower portion of the cable can be in an auxiliary conduit to a main tubular and be installed already connected to sensors, instruments or other downhole equipment. The connection is made up downhole to connect a string with its auxiliary conduit to the portion of the string and its auxiliary conduit that are below. The cable already in the hole has an upper end ferrule for connection to a ferrule on the lower end of a cable delivered into the upper auxiliary conduit after the wet connect is made up. When the ferrules connect they are held together and a signal goes to the surface that they have connected. The auxiliary connected conduits have a lateral conduit in fluid communication for use in delivery of the cable with circulating fluid.

Abstract: An all electric subsea tree can be coupled with a hydraulic pressure unit that is fed off electrical and control lines that are in the umbilical from the surface. In that way hydraulic lines do not need to be separately run from the surface to the tree. Alternatively hydraulic pressure can be generated at a downhole tool using power and control lines running from the tree to the downhole equipment. As another alternative, the downhole equipment can be run by electric motor located downhole adjacent the downhole equipment and powered and controlled by lines running from the tree to the downhole location.

Abstract: A spanner joint assembly for connecting between an upper riser and a conventional dual bore tubing hanger in a subsea well. The spanner joint assembly includes upper and lower spanner joint portions connected to each other through an emergency disconnect portion. The upper spanner joint portion has a longitudinal production bore and a longitudinal annulus. The lower spanner joint portion has a longitudinal production bore with a production bore valve and a longitudinal nonconcentric annulus access bore. The emergency disconnect portion includes an upper mandrel connected to the upper spanner joint portion and a lower mandrel connected to the lower spanner joint portion.

Abstract: A surface controlled electrically operated solenoid subsurface safety valve is positioned in a well tubing in a well and controlled by an electrical control line extending from the solenoid coil to the well surface. One or more measuring sensors are positioned in the well for measuring a physical property of the well. The input of the sensor is connected to the control line for receiving electrical power and the output of the sensor is connected to the control power for supplying an output signal proportional to the measurement of the physical property. The output signal is distinguishable from the electrical supply current to the solenoid coil. A signal processor at the well surface receives the sensor output. Preferably the sensors are connected in parallel with at least a portion of the solenoid coil.

Abstract: A subsurface solenoid well safety valve which is locked in the open position, after being opened mechanically, for preventing the valve from closing. A valve closure member is controlled by a tubular member which is mechanically moved downwardly to open the valve. An armature movable in the housing is actuated by a solenoid coil for locking the tubular member in the open position to the valve housing. Deenergization of the coil releases the armature and the lock and allows the tubular member to be biased to the open position.

Abstract: A subsurface solenoid operated well safety valve which is locked in the open position, after being opened by the solenoid, for preventing the valve from closing by various forces overcoming the solenoid. A valve closure member in the bore of a housing moves between open and closed positions and is controlled by a tubular member which is biased in a direction to close the valve. An armature is movable in the housing and a solenoid coil is energized to move the armature. A first releasable lock connects the armature to the tubular member for allowing the movement of the solenoid to open the valve. The first lock is released when the valve is opened. A second releasable lock locks the tubular member to the housing in the open position prior to the release of the first lock means. The de-energization of the coil releases the armature and the second lock to allow the valve to close.
