    • A wellbore fluid comprises an aqueous carrier liquid, hydrophobic particulate material suspended therein and a gas to wet the surface of the particles and bind them together as agglomerates. The hydrophobic particulate material has a specified maximum particle size and/or minimum surface area: namely a volume median particle size d50 of not more than 200 micron, determined as median diameter of spheres of equivalent volume and/or a surface area of at least 30 m2 per liter (0.03 m2 per milliliter), determined as surface area of smooth spheres of equivalent volume.The agglomeration of the particles by gas leads to the formation of agglomerates which contain gas and so have a bulk density lower than the density of the particles. This reduces the rate of settling. The fluid is particularly envisaged as a slickwater fracturing fluid in which the suspended particles are proppant. We have found that the small particle size and/or substantial surface area increases the amount of gas which can be retained within agglomerates and so enhances the buoyancy of the agglomerates. The end result is that a greater proportion of a hydraulic fracture is propped open.
    • 井眼流体包括水性载体液体,悬浮在其中的疏水性颗粒材料和用于润湿颗粒表面的气体并将其作为附聚物结合在一起。 疏水性颗粒材料具有规定的最大粒径和/或最小表面积:即体积中值粒径d50不大于200微米,确定为等体积的球体的中值直径和/或至少30的表面积 m2 /升(0.03平方米/毫升),确定为相当体积平滑球面的表面积。 通过气体的颗粒附聚导致形成含有气体的聚集体,因此其密度低于颗粒的密度。 这降低了沉降的速度。 流体特别设想为浮水压裂液,其中悬浮颗粒是支撑剂。 我们已经发现,小的颗粒尺寸和/或实质的表面积增加了可以在附聚物中保留的气体的量,并且因此增强了附聚物的浮力。 最终的结果是水力裂缝的比例较大。

    • Methods, systems, and computer program products for multiplexing a target communication port to provide an additional independent communication channel sharing at least some portion of hardware associated with the target port. Typically, a device, such as a disk drive, is also connected to the target port. An out-of-band signal indicates when the shared hardware is being used to provide the additional independent communication channel to avoid interfering with the target port device. A communication board with one or more communication ports may be coupled to the additional independent communication channel for communicating data from the target system to other devices or systems, such as a host system, through the communication board. In communicating with the target system, the communication board may emulate a particular interface that is supported by the target port. One type of host system may be a development system for designing, testing and debugging the target system.
    • 用于复用目标通信端口以提供附加独立通信信道的方法,系统和计算机程序产品,共享与目标端口相关联的硬件的至少一部分。 通常,诸如磁盘驱动器的设备也连接到目标端口。 带外信号指示共享硬件何时被用于提供额外的独立通信信道,以避免干扰目标端口设备。 具有一个或多个通信端口的通信板可以耦合到附加的独立通信信道,用于通过通信板将目标系统的数据传送到诸如主机系统的其他设备或系统。 在与目标系统通信时,通信板可以模拟由目标端口支持的特定接口。 一种类型的主机系统可以是用于设计,测试和调试目标系统的开发系统。
