摘要： Elongated shapeable particles, for example bi-component fibers that are reshaped into tighter structures when heated, are injected into fractures generated during acid fracturing. Collections of such particles form as the temperature in the fracture increases, heterogeneously masking portions of the fracture faces and causing differential etching and increased fracture conductivity when formation-dissolving agents contact the fracture faces. Optionally, the elongated shapeable particles may decompose to release formation-dissolving agents.
