20110220362 | Method and Materials for Proppant Flow Control With Telescoping Flow Conduit Technology - Porous objects, such as porous balls, may be employed within telescoping devices to control proppant flowback through a completed well during production. The telescoping devices may connect a reservoir face to a production liner without perforating. Acid-soluble plugs initially disposed within the telescoping devices may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes. The porous balls may then be inserted into the telescoping devices to block proppant used in the fracturing process from flowing out of the reservoir with the production fluids. | 09-15-2011 |

20110315226 | Telescoping Conduits With Shape Memory Foam as a Plug and Sand Control Feature - 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. | 12-29-2011 |

20120298351 | Fracturing Nozzle Assembly with Cyclic Stress Capability - A fracturing jet nozzle assembly features a series of angles nozzles on a rotatably mounted plate that operates in conjunction with a central nozzle or nozzles. The slanted nozzles are aimed into the perforation where the central nozzle is aimed directly so that the rotation of the nozzle plate from the slanted nozzles results in cyclic impacts in the perforation from where the fractures will propagate. The cyclic loading results in greater fracture formation and propagation. In another variation, relatively movable plates employing slanted nozzles rotate one plate with respect to another to get the effect of cyclic pulses of jetting fluid impingement in the perforation to enhance formation and propagation of fractures from the perforation. | 11-29-2012 |
20120298781 | Enhanced Penetration of Telescoping Fracturing Nozzle Assembly - A fracturing jet nozzle assembly has nested telescoping sections that each have nozzles in them. The outermost stage makes for a large perforation as it and the adjacent stages begin extension. As the stage adjacent the outermost stage continues to extend into the perforation and reaches maximum extension the nozzles in the outermost stage are cut off from fracturing fluid flow and that flow is in turn redirected to the remaining stages that have not yet fully extended. The innermost stage preferably does not get cut off from jet fluid flow even at its full extension. | 11-29-2012 |
20130000914 | Through Tubing Expandable Frac Sleeve with Removable Barrier - 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. | 01-03-2013 |
20130020089 | TUBULAR VALVING SYSTEM AND METHOD - A tubular valving system includes, a tubular, a seat, a sleeve movably engaged with the seat between at least a first position, a second position and a third position, a release member between the sleeve and the seat that maintains the sleeve relative to the seat in the first position until release thereof, a biasing member configured to urge the sleeve from the second position toward the third position, and a flapper sealingly engagable with the seat. A first threshold pressure against the seated flapper causes release of the release member allowing the sleeve and the seat to attain the second position. A subsequently drop in pressure against the seated flapper below a second threshold level allows the biasing member to move the sleeve relative to the seat to the third position thereby unseating the flapper from the seat and preventing the flapper from again seating with the seat. | 01-24-2013 |
20130043021 | Subterranean Vibrator with Lateral Vibration Feature - A vibratory tool for use in a tubular string to prevent sticking or to release a stuck string features a fluid operated dart valve working in conjunction with an impact sleeve to deliver continuous axial jarring blows in opposed directions as long as flow is maintained. Movement of one of those components axially in opposed directions opens and closes access to opposed lateral ports so that a lateral vibration is also established as flow cyclically occurs and stops sequentially at opposed lateral outlets. | 02-21-2013 |

The screen assembly carries a series of chambers internally that are located between the producing zones generally in the area of blank pipe between the zones. The wash pipe has a shifter associated with it so that extraction of the wash pipe after gravel packing will serially shift pistons that reduce chamber volume where the chemical is stored. The chemical will exit through a rupture disc and nozzle and will commingle with the gravel and make an impervious annular barrier. | 05-23-2013 |
