摘要： A transition piece is provided near an end of a screen assembly to allow transition from a lighter weight and collapse resistant pipe under the screen sections to a heavier wall and higher collapse strength pipe between the top of the screen and the isolation packer. When a screen out occurs, the heavier wall pipe can handle the new pressures that are applied to the formation and to the tubular to try to collapse it. The screen portion can still be built with thinner wall pipe as the screen out condition protects that pipe from collapse pressure because the fully gravel packed annular space keeps the surface applied pump pressure from exerting a collapse force on the base pipe under the screen. The internal diameter under the screen does not have to be reduced because the heavy wall pipe is not provided there. Above the screen, a heavy wall pipe can be provided because the absence of the screen layer allows more room for a larger pipe with thicker wall without decrease in internal diameter as compared to under the screen.
摘要翻译：在屏幕组件的端部附近设置过渡件，以允许从屏幕部分下方的较轻重量和抗倒塌管道过渡到屏幕顶部和隔离封隔器之间的较重壁和较高的塌陷强度管。当出现筛选时，较重的壁管可以处理施加到地层和管子的新压力以试图将其压扁。屏幕部分仍然可以用更薄的壁管构建，因为屏幕排出状态保护管道免受坍塌压力，因为完全砾石填充的环形空间使表面施加的泵压力不会在屏幕下方的基管上施加塌陷力。因为没有设置厚壁管，屏幕下方的内径不必减小。在屏幕上方，可以提供厚壁管，因为与屏幕下方相比，没有屏幕层允许具有较厚壁而不减小内径的较大管道的空间更大。

摘要： The present invention is directed to systems and methods for initiating annular obstructions in wells used in, or in support of, enhanced oil recovery operations—particularly enhanced oil recovery (EOR) efforts involving steam injection (e.g., steam flooding). In at least some instances, system and method embodiments of the present invention utilize one or more passively-activated annular obstruction devices (and/or hybrid active/passive devices) for inducing annular obstruction, wherein the associated passive or hybrid activation is at least partially controlled by thermal means such that it can be deemed to be thermally-directed or thermally-controlled. Such thermally-directed passive activation can afford considerably more control over the annular obstruction process and, correspondingly, over the overall steam injection into the formation and associated reservoir—thereby providing more efficient recovery of hydrocarbons.

摘要： A fluid loss valve is disposed in a wash pipe in a gravel packing assembly. It is preferably held open initially and when in the process it is time for the valve to be able to go closed a pulling force is applied that creates relative movement to either close the valve or allow it to close without release of the assembly when under tension. This allows a surface signal that the valve is to be released for closure. The tension is relieved before string movement with the valve can occur. This can happen by slacking off before picking up again or through other time delay features that allow the tension to be removed and a lock to collapse before a lift force is applied for subsequent gravel packing operations. The valve in its closed position acts to eliminate fluid loss when excess gravel is reversed out.

摘要： A crossover tool assembly is run in with a packer and after the packer is set it is released from the packer for independent movement. The assembly is picked up to allow spring loaded dogs to come out so that upon setting down weight the crossover assembly has an outer assembly that is supported on the packer mandrel. The crossover mandrel can then be set down and picked up to operate a j-slot mechanism in the crossover. Relative movement induced by the j-slot with the outer assembly of the crossover supported by the dogs allows a return path within the crossover to be opened or closed independent of any contact with the packer mandrel.

摘要： A frac pack system and method for operating a frac pack system wherein an isolation string assembly has a lower circulation valve with lateral flow ports that are operated to an open position without the use of shifters on a wash pipe. The isolation string assembly is incorporated into a frac pack assembly within a wellbore and includes an upper sleeve tool that provides selective production of fluids through the frac pack assembly. In addition, the isolation string includes a lower circulation valve having a sliding sleeve that is shiftable from an open position to a closed position upon receipt of a suitable pressure differential. This configuration is particularly valuable for permitting monitoring of pressure or other conditions in the annulus of the wellbore portion being packed during frac pack operations. Further, the lower circulation valve tool can be used to selectively allow fluid returns during the frac pack operation.

摘要： Systems and methods for guiding a seal assembly associated with a string of production tubing, or a tubular member generally, into a receptacle within a wellbore. The muleshoe of a seal assembly is provided with an auto entry guide device in the form of a guide member or kickover lug that is radially moveable with respect to the muleshoe. The kickover lug is collapsible radially inwardly and biased radially outwardly. The auto entry guide device may also include a centralizer bowspring that is mounted upon the muleshoe. Additionally, the muleshoe is mounted for rotational movement with respect to the seal assembly.
