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. |
