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 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.

摘要： A gravel packing method and apparatus so that when setting the packer, a ball is dropped to a seat that is isolated from the effects of formation pressures when trying to set the packer. This is accomplished by isolation of the gravel pack outlet port when setting the packer and locating the ball seat in a position where the effects of formation pressure are irrelevant. Additionally, by positioning the evacuation ports above a seal bore in the screen extension during circulation to deposit gravel and further putting check valves in the evacuation ports, the evacuation step after circulation can be accomplished without having to reposition the crossover.
摘要翻译：一种砾石包装方法和装置，使得当设置封隔器时，当试图设置封隔器时，将球落到与地层压力的影响隔离的座椅上。这是通过在设置封隔器时将砾石包装出口隔离并将球座定位在地层压力的影响无关的位置来实现的。此外，通过在循环期间将排出口定位在筛网延伸部中的密封孔上方以沉积砾石并进一步将止回阀放入抽空口中，可以实现循环后的抽空步骤，而无需重新定位交叉。

摘要： The present invention is, in some embodiments directed to methods for optimizing wellbore displacement operations via in situ fluid property assessment/monitoring. By monitoring fluid properties in situ (i.e., downhole), fluid property assessment is direct instead of being inferred. Additionally, wherein such assessment/monitoring is carried out in real time, changes to the displacement fluid can be made “on-the-fly,” thereby contributing to an enhancement of the overall efficiency of the method.

摘要： The present invention is directed to completion fluid compositions and methods of making same. Such completion fluids are unique in that they utilize nanoparticles as weighting (densification) agents that increase the specific gravity (or density) of the fluid into which they are dispersed. Depending on their properties, such nanoparticulate weighting agents can vastly broaden the types of base fluid used in the completion fluid, permitting the use of non-aqueous and even hydrocarbon base fluids. Additionally, such nanoparticle-densified completion fluids can provide reduced environmental risks, and the nanoparticle weighting agents used therein can be more easily recovered from the based fluids into which they are dispersed.

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.
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。
