摘要： A control system for a subsurface safety valve references the surrounding annulus to put the operating piston in pressure balance. Depending on the configuration and which seal in the system fails, the various embodiments can differ in their failure modes. With the lower end of the piston exposed to annulus pressure all failure modes close the flapper. With the lower end of the piston exposed to tubing pressure, failure of any of the seals except one will result in flapper closure.

摘要： Thin wall sleeves are inserted into a well and expanded into sealing position to a surrounding tubular. Each sleeve has a ball seat. A zone is perforated after a sleeve is secured in position below the perforations. The ball is dropped onto the seat and pressure is built up to complete the fracturing. After all zones are perforated and fractured, the balls are removed, preferably by dissolving them and the thin walled sleeves are left in the tubular against which they have been expanded. Production can then begin from a selected zone. The objects can be of the same size for each sleeve. The sleeves can be run through tubing and into casing. Acid can be pumped to dissolve the objects.

摘要： A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.

摘要： A debris removal tool has a lower end pickup hose into which debris laden fluid is pulled when there is circulation through the debris removal tool from the surface. An anchor near the open end of the hose stabilizes the lower end near a recess or groove from which debris is to be removed. Once the anchor is set the hose can be extended or retracted as well as rotated on its axis to pick up debris. A camera can be located in or near the hose opening to be able to see where the debris is located and for confirmation that the debris is being removed and that the debris has fully been removed.

摘要： A string with a plurality of telescoping members has the telescoping members initially sealed preferably with a shape memory foam so that the foam is initially impervious when run into a subterranean location. Then, after extension of the telescoping members, using pressure in the string, the foam gets above its transition temperature and grows axially in a passage of the telescoping members, to the point of becoming porous so that it can serve as a sand control or other debris exclusion device. Plates with openings can be deployed at opposed ends to maintain the assembly in position when subjected to differential pressure as flow goes through the foam. Alternative materials are envisioned.

摘要： A valve is mounted to a tubular string and has an actuation assembly that is isolated from well fluids. The valve member can be a ball that rotates on a pivot and is actuated by relative rotation of string components that straddle the ball. Rotation of one string component is linked to the closure ball by an external slanted slot with an operating ball that rides in it and connects the rotating string component to the closure ball. Travel stops limit the desired rotation of the closure ball in opposed directions. The closure ball can alternatively be rotated by relative longitudinal string component movement that is converted to relative rotation such as through the use of a j-slot mechanism. Internal seals isolate the slanted slot and operating ball from well fluids.

摘要： A screen section is made with variable resistance to flow in the screen material to balance the flow along the screen length. In one variation different discrete zones have screens configured for different percentages of open area while all have the same particle filtration capability. In another variation discrete portions have differing amounts of overlapping screen portions so as to balance flow without affecting the particle size screened. The cross-sectional shape of a wire wrap underlayment for the screen is made closer to trapezoidal to decrease the angle of opening for the incoming flow paths toward the base pipe. In this manner flow resistance is reduced and flow is increased due to reduced turbulence.

摘要： A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. In some embodiments the solids come out of openings in the side of the inlet pipe and in others the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.
摘要翻译：地下碎屑捕集器通过在入口管的内侧放置凹槽或螺旋突起来旋转进入的碎屑流。在一些实施方案中，固体从入口管侧面的开口出来，而在另一些实施方式中，固体可以直接从顶部出口离开出口直接进入封闭的固体容积中，或者固体可以直接排出入口管进入由外壳限定的较大的开放空间。在后一种情况下，内部壳体壁可以具有屏幕或叶片，当流体继续到壳体出口并且最终到达出口屏幕之前，当放电到达表面或者沿着外部的外部再循环时，固体颗粒减慢该工具进入管道，同时拾取额外的碎屑。

摘要： A cutting assembly for external conduits on a tubing string features a breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing. Upon severing of the string and applying a pickup force, a tension is applied to each external conduit since the severing of the string happens above all the cutter housings. Each housing cuts at least one conduit and the upper portion of the string brings with it the upper portion of the external conduit while the lower portions of each cut external conduit are retained in the cutter housings that remain downhole below the breakaway. In that manner there are no loose external conduit ends to interfere with and/or disturb subsequent fishing or other wellbore operations.
