摘要： The productivity of sandstone or carbonate formations is enhanced by contacting the formation with a deformable particulate and a HF-containing acidizing solution. The deformable particulates create a partial monolayer in the formation while the HF-containing acidizing solution differentially etches the rock around the deformable particulate. The surface of the formation is partially blocked from reaction with the acidizing solution by the creation of the partial monolayer. Conductive channels are therefore created on the surface of the formation. The deformable particulates deform on closure. As the closure stress increases, the formation faces compress the non-dissolved, sandwiched formation points. These points function as pillars of un-reacted formation and act similar to a partial monolayer of proppant, providing the highly conductive channels.
摘要翻译：通过使地层与可变形的颗粒和含HF的酸化溶液接触，提高砂岩或碳酸盐岩层的生产率。可变形颗粒在地层中产生部分单层，而含HF的酸化溶液在可变形颗粒周围差异地蚀刻岩石。通过产生部分单层，地层的表面部分被阻止与酸化溶液的反应。因此，导电通道在地层的表面上产生。可变形的颗粒在闭合时变形。随着闭合应力增加，形成面压缩未溶解的夹层形成点。这些点作为未反应形成的柱子起作用，类似于支撑剂的部分单层，提供高导电通道。

摘要： Solid surfactant suspension compositions are formed by combining solid surfactants, such as alpha-olefin sulfonates, with an organic base fluid, such as diesel. Solid surfactant suspensions may be combined with an aqueous carrier fluid to form surfactant-containing fluids suitable for, among other things, forming foams or for water wetting surfaces. Solid surfactant suspensions may also be combined with additive materials, such as polymer particles, to form a dispersion or emulsion. Polymer-containing solid surfactant suspensions may also be combined with aqueous carrier fluids to form, for example, viscosified, gelled, or foamed fluids. Concentration of solid surfactant materials contained in a solid surfactant suspension may be varied to affect the function the solid surfactant suspension. For example, the solid surfactant material may function as a polymer surface wetting agent, an emulsifier, a dispersant, a viscosifier, and/or a foamer in well completion and remedial and/or workover fluids.
