    摘要： Fluid compositions and methods of making and using same are described, one composition comprising a well treatment fluid and an additive combined with the well treatment fluid, wherein the additive is selected from solids, liquids and combinations thereof, the additive having a surface shape, at least one property of the surface shape enabling it to change under influence of a controllable parameter after the composition is deployed into a hydraulic fracture or gravel pack. In methods of the disclosure, the additive exists initially in a first state, and then is changed to a second state. The first state may increase proppant flowback efficiency, while the second state may increase hydraulic conductivity. In certain embodiments, the additive may change back to its first state.

    摘要翻译： 描述了制备和使用它们的流体组合物和方法，一种组合物包含井处理流体和与井处理流体组合的添加剂，其中添加剂选自固体，液体及其组合，添加剂具有表面形状， 表面形状的至少一个性质使得其在组合物部署到水力裂缝或砾石包装之后在可控参数的影响下变化。 在本公开的方法中，添加剂最初存在于第一状态，然后变为第二状态。 第一种状态可能会增加支撑剂回流效率，而第二种状态可能会增加水力传导性。 在某些实施方案中，添加剂可以改变回其第一状态。

    摘要： Composition including a fluid and a plurality of solid particles dispersed in the fluid. The plurality of solid particles includes a thermoplastic composition having a softening temperature in a range from 50° C. to 180° C. and a curable resin; optionally at least some of the particles in the plurality of solid particles comprise both the thermoplastic composition and the curable resin. The solid particles have an average aspect ratio of less than 2:1. A method of modifying a wellbore within a geological formation is also disclosed. The method includes introducing the composition into the wellbore. A method of making a plurality of particles, for example, to use in the composition, is also disclosed.
