Abstract: A wellbore fluid comprises an aqueous carrier liquid, hydrophobic fibers suspended therein, hydrophobic particulate material also suspended in the carrier liquid, and a gas to wet the surfaces of the particles and fibers and bind them together as agglomerates. The wellbore fluid may be a slickwater fracturing fluid and may be used for fracturing a tight gas reservoir. Using a combination of hydrophobic particulate material, hydrophobic fibers and gas inhibits settling out of the particulate material from an aqueous liquid. Because the gas acts to wet the surfaces of both materials and agglomerates them, the particulate material is made to adhere to the fibers; the fibers form a network which hinders settling of the particulate material adhering to them, and the agglomerates contain gas and so have a bulk density which is less than the specific gravity of the solids contained in the agglomerates.

Abstract: A wellbore fluid is an aqueous carrier liquid with first and second hydrophobic particulate materials suspended therein. The first hydrophobic particles have a higher specific gravity than the second hydrophobic particles and the fluid also comprises a gas to wet the surface of the particles and bind them together as agglomerates. The fluid may be a fracturing fluid or gravel packing fluid and the first particulate material may be proppant or gravel. The lighter second particulate material and the gas both reduce the density of the agglomerates which form so that they settle more slowly from the fluid, or are buoyant and do not settle. This facilitates transport and placement in a hydraulic fracture or gravel pack. One application of this is when fracturing a gas-shale with slickwater. The benefit of reduced settling is better placement of proppant so that a greater amount of the fracture is propped open.

Abstract translation: 井眼流体包括水性载体液体，悬浮在其中的疏水性纤维，还悬浮在载体液体中的疏水性颗粒材料，以及将颗粒和纤维的表面湿润的气体，并将其作为附聚物结合在一起。 井筒流体可以是一个滑水压裂液，并可用于压裂一个紧密的气藏。 使用疏水性颗粒材料，疏水性纤维和气体的组合可以防止从水性液体中沉淀出颗粒物质。 因为这些气体用来润湿两种材料的表面并使它们聚集，所以使颗粒材料粘附到纤维上; 纤维形成阻碍粘附在其上的颗粒材料的沉降的网络，并且附聚物含有气体，因此其堆积密度小于附聚物中所含固体的比重。
