| A ball within a ball valve comprises an interior fluid passage extending through the ball, a first flow passage disposed in the ball that allows fluid communication between an exterior fluid and the interior fluid passage, a second flow passage disposed in the ball that extends through a wall of the ball to the interior fluid passage, where the first flow passage and the second flow passage are on opposite hemispheres of the ball, and a flow through device. The flow through device comprises a plug disposed in the second flow passage and configured to sealingly engage the ball, and a shear device configured to engage the plug and retain the plug in the first flow passage or the second flow passage. The shear device may comprise a shear ring, a shear pin or a shear screw. | ||||||

A device for use in a subterranean well. The device comprising an actuator sleeve (210) coupled to an actuated element (200) of the device to operate the actuated element when the actuator shifts axially in the device, and an actuator (220) comprising a spring (222) to act on the actuator sleeve (210). The actuator is responsive, independent of well annulus pressure, to a remotely generated hydraulic signal in a central bore (208) of the device to change from an unactuated state, with the spring compressed, to an actuated state, with the spring expanded to shift the actuator sleeve from a first position to a second position, and the actuator is responsive to reset to the unactuated state when the spring is recompressed.

| 90 | HIGH-RATE INJECTION SCREEN WITH ONE-WAY VALVES | EP15150122.8 | 2015-01-05 | EP2891763B1 | 2018-05-16 | Hall, Christopher A |
| A screen assembly can be used for "gravel pack" or "frac pack" operations and can then withstand high rate injections. The disclosed screen assembly is able to withstand the flow of the packing operation by not allowing fluid passage from the annulus to inside the screen assembly. Then, the screen assembly can be opened and facilitate high rate injection for the life of the well. To achieve this, the disclosed screen assembly does not allow slurry flow to enter the screen assembly during the packing operation. Then, after the packing is completed, the screen assembly provides enough open flow area so that a high injection rate with solid content can be introduced into the annulus without eroding the screen. | ||||||

| A downhole tool has a housing, a mandrel, a seat, and a piston. The housing defines a first bore, and the mandrel is movably disposed in the first bore and defines a second bore. The mandrel has first and second mandrel sections or upper and lower cones, and the first mandrel section defines a cross-port communicating the second bore with an annular space between the mandrel and the housing. The seat is disposed in the first bore of the housing between the first and second mandrel sections. The seat is movable to a constricted state in the first bore to catch a dropped ball and is movable to an expanded state in the first bore to pass a dropped ball. The piston is disposed in the annular space and at least temporality supports the seat in its constricted state. | ||||||

| A downhole tool has a housing, mandrel, and ball seat. The housing defines a first bore, and the mandrel defines a second bore. The mandrel is disposed in the first bore of the housing and defines an annular space with the housing. The ball seat is rotatably disposed in the second bore of the mandrel and defines an interior passage with a seat profile. First and second pistons are disposed in the annular space on opposing sides of the ball seat. These first and second pistons are movable along an axis of the tool in the annular space in opposing directions and are adapted to rotate the ball seat. Additionally, first and second biasing members are disposed in the annular space and bias the first and second pistons toward one another to reset the ball seat in the absence of pressure. | ||||||

| A valve system for providing fluid flow through radial openings disposed along an axial length of a tubular. The tubular comprises at least one valve group containing at least two valves operable by one drop ball. An inset 302 e.g. of standard grade steel provided in a harder liner 301 in the opening provides an intermediate small opening for at least the time required to open all the remaining valves in the group. The small opening limits the pressure drop over the valve. When all valves are open, the insets 302 are eroded away by an abrasive material, e.g. a slurry used for hydraulic fracturing, and permanent full openings are created. | ||||||
| 94 | WELLHEAD SAFETY VALVE ASSEMBLY | EP15786205 | 2015-04-30 | EP3137726A4 | 2018-02-07 | LANDRY HAROLD WAYNE |
| A valve assembly is installed within a wellhead such as a conventional tubing hanger or casing hanger used to suspend pipe or other tubular goods in a well. A seal bushing assembly is installed in a tubing head assembly or other wellhead component. A hanger valve assembly is stung into the seal bushing assembly and includes a valve that can be selectively opened or closed. In the open position, the valve does not restrict a central flow path diameter through the hanger and wellhead. In the closed position, the valve contains pressure and/or fluid flow and fully seals against wellbore pressure acting on the valve. A wellhead adapter covers the hanger valve assembly and provides an attachment point for a conventional Christmas tree or other wellhead equipment. | ||||||

In another embodiment, the apparatus comprises a motor operating system disposed in a motor system housing, a shaft operatively connected to the motor operating system, the shaft having a passageway, and a divert assembly disposed to direct fluid flow selectively to the motor operating system and the passageway in the shaft. In another aspect, methods and apparatus for directionally drilling a casing into the formation are disclosed. Methods and apparatus for measuring the trajectory of a wellbore while directionally drilling a casing into the formation are also described.

| Systems and methods for using propellant as a force generator in component actuation are disclosed. One embodiment may take the form of a method including deploying at least one component to a subsea location, controlling operation of the at least one component using a control system, and igniting a propellant.

Another embodiment may take the form of a subsea system including a control system, a propellant system in communication with the control system, and a component in communication with the propellant system. The propellant system is ignitable by the control system upon receipt of a ignite signal and upon losing communication with the control system after being placed in an armed state by the control system. The component is actuatable by the propellant system after ignition of the propellant system. | ||||||

| An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured tool body assembly having valving members (e.g., safety or kelly valves) and valving members holding plugs, balls, or darts to be dropped. A transmitter (or transceiver) provides an ability to generate a wireless signal that is received by receivers (or transceivers) on the tool body assembly. Each receiver (or transceiver) controls an electrical actuator that engages a valving member. Wireless signals can be used to open or close a selected valving member. | ||||||
