A downhole tool (100) is responsive to passing objects and applied fluid pressure. A plugless valve (120) in the tool (100) is operable from an unobstructed condition to an obstructed condition unobstructing the tool's bore (104) to an obstructed condition obstructing the tool's bore (104) to the applied fluid pressure. An indexer (130) counts the objects passing through the tool's bore (104) and permits operation of the plugless valve (120) from the unobstructed to the obstructed condition in response to the counted number. The applied fluid pressure in the bore (104) obstructed by the plugless valve (120) can then communicate outside the tool (100) via at least one port (106). The plugless valve (120) can have a movable insert that moves relative to a flapper. The indexer (130) can use ratcheting dogs, collet, J-slot, electronic sensor, and other components to count the passing objects.

| A technique facilitates valve operations in many applications including well related applications. A valve utilizes a piston which moves along an arc. The valve has an outer housing and an inner housing spaced to create an arcuate pressure chamber which extends along the arc. A piston is mounted in the arcuate pressure chamber for movement along the arc. A hydraulic force or other force may be selectively applied directly against an end of the arcuate piston to shift the arcuate piston along the arc. In some applications, the piston comprises a cutting edge oriented to enable performance of a cutting operation. | ||||||

| 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 wellbore ball valve includes a ball-type valve closure having an interior, central bore. A lower ball carrying assembly defines a first annular, sealing seat surface in contact with and adapted to seal with the exterior of the valve closure. The first seat surface defines a first through hole. An upper assembly defines a second annular seat surface in contact with the exterior of the valve closure. The second seat surface defines a second through hole. The second through hole is shaped differently from the first through hole in that it at least partially overlaps with the central bore while the first through hole is sealed from the central bore. | ||||||

| A pressure responsive downhole tool comprises a power piston pressure relief valve that is selectively activated and deactivated to allow pressure-related operations to be conducted. The pressure relief valve will not open until the power piston is activated, which also requires the operating element (ball valve, for example) to be opened, thereby avoided situations in which the ball valve is inadvertently placed in the Lock Open position. | ||||||
| 238 | HIGH-RATE INJECTION SCREEN WITH CHECKABLE PORTS | EP15150122.8 | 2015-01-05 | EP2891763A2 | 2015-07-08 | 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.

| The present Invention relates to a device and a method for perforating downhole casings. The method comprises the steps of arranging a device (1) comprising a pipe section (3) on a drill string, running the device (1) into a bore hole to a desired location in the well, dropping a ball (7) down through the drill string down to the device (1), where the ball (7) rests in a ball seat (5), thus blocking fluid communication between the inside and the outside of the device (1), whereby the pressure on the Inside of the d rill string and the device (1) is pumped up to a first pressure level and a first sequence of pressure rises and pressure reliefs is carried through within a first pressure level Interval, whereby a firing system (4), arranged to react to said first sequence of pressure rises and pressure reliefs, triggers a charge or group of charges (2), whereby the charge or group of charges (2) punches one or more holes through a surrounding casing wall, driving the pressure on the inside of the drill string further up to a second level causing a rupture disc (8), arranged in an opening (10) in the pipe wall to the pipe section (3) somewhere above the ball seat (5), to burst and establishing a fluid communication between the inside and outside of the drill string through the opening in the pipe wall of the pipe section (3), and to start a circulation In the well by pumping a fluid down through the drill string and out through the opening which is created when the rupture disc (8) bursts. | ||||||
