    • A method of recovering hydrocarbons from a porous subterranean hydrocarbon-bearing formation comprising: (a) feeding a first stream comprising a high salinity water to a first side of a semipermeable membrane of at least one forward osmosis unit of a desalination plant and feeding a second stream comprising an aqueous solution of a removable solute to a second side of the semipermeable membrane wherein the solute concentration of the aqueous solution of the removable solute is sufficiently greater than the solute concentration of the high salinity water that water passes through the semipermeable membrane from the high salinity water into the aqueous solution of the removable solute to form a diluted aqueous solution of the removable solute; (b) withdrawing a third stream comprising a concentrated brine and a fourth stream comprising a diluted aqueous solution of the removable solute from the first and second sides respectively of the semipermeable membrane of the forward osmosis unit; (c) substantially separating the removable solute from the fourth stream comprising the diluted aqueous solution of the removable solute to form a low salinity water stream having a total dissolved solids content of less than 5000 ppm; (d) if necessary, increasing the salinity of the low salinity water stream to a total dissolved solids content of at least 200 @ @ m; (e) introducing the treated low salinity water into the hydrocarbon-bearing formation via an injection well; (f) displacing the hydrocarbons with the treated low salinity water towards an associated production well; and (g) recovering hydrocarbons from the formation via the production well.
    • 一种从多孔地下含烃地层回收烃的方法,包括:(a)将包含高盐度水的第一物流供给至少一个脱盐设备的至少一个正渗透单元的半透膜的第一侧,并将第二物流 包含可去除溶质的水溶液到半透膜的第二侧的流,其中可除去溶质的水溶液的溶质浓度足够大于水从半透膜中通过半渗透膜的高盐度水的溶质浓度 高盐度水进入可除去溶质的水溶液中形成可去除溶质的稀释水溶液; (b)从正向渗透单元的半透膜的第一侧和第二侧排出包括浓缩盐水和第四料流的第三料流,所述第四料流包含可除去溶质的稀释水溶液; (c)将可移除溶质与包含可除去溶质的稀释水溶液的第四料流基本分离,以形成总溶解固体含量小于5000ppm的低盐度水流; (d)如有必要,将低盐度水流的盐度提高至至少200 @ m的总溶解固体含量; (e)通过注射井将经处理的低盐度水引入含烃地层; (f)将处理过的低盐度水代替烃与相关的生产井; 和(g)通过生产井从地层回收碳氢化合物。

    • An emulation component for a data backup system is provided. The emulation component represents a storage device, such as a flash memory device or a partition of a disk drive, as if it were an auto-launch device, that will trigger applications to execute automatically. Accordingly, other computing systems, such as personal computers, interact with the storage device, through the emulation component, as if the storage device were the auto-launch device. Because the emulation component makes this representation, merely connecting the emulation component between the storage device and the computing system can cause a backup application stored on the storage device to automatically execute on the computing system. A data backup appliance including an emulation component and a storage device is also provided. The backup system can also include an interface for connecting another removable device, such as a disk drive, for storing backup content from the data source.
    • 提供了一种用于数据备份系统的仿真组件。 仿真组件表示存储设备,例如闪存设备或磁盘驱动器的分区,就像它是自动启动设备一样,将触发应用程序自动执行。 因此,诸如个人计算机的其他计算系统通过仿真组件与存储设备交互,就像存储设备是自动发射设备一样。 由于仿真组件做出这种表示,只需将存储设备和计算系统之间的仿真组件连接起来,就能够使存储在存储设备上的备份应用程序在计算系统上自动执行。 还提供了包括仿真组件和存储设备的数据备份设备。 备份系统还可以包括用于连接另一个可移动设备(如磁盘驱动器)的接口,用于从数据源存储备份内容。
