Hydro-fracking of a typical gas well in Australia consumes around 3000 tonnes of proppants to keep open the created fractures, costing over $1.5 million. This project investigates proppant transport behaviour in non-Darcy turbulent flow during fracking of underground reservoir rock by combining Hele-Shaw-cell experiments with Particle Image Velocimetry and conceptual/numeric modelling. The generating advanced proppant transport knowledge is expected to be more accurate than laminar flow-based theories currently relied on. Expected outcomes include more efficient/safer proppant-assisted fracking strategies to reduce wasteful proppant disposition and inform industry/government management of fracking based on the reservoir geological features.

在澳大利亚，一口典型的气井的水力压裂法消耗约3000吨支撑剂来保持裂缝的开放，成本超过150万美元。该项目研究了地下储层岩石压裂过程中支撑剂在非达西湍流中的运移行为，方法是将Hele-Shaw细胞实验与粒子图像测速技术和概念/数值模拟相结合。预计生成的先进支撑剂运输知识将比目前依赖的基于层流的理论更准确。预期结果包括更有效/更安全的支撑剂辅助压裂策略，以减少浪费的支撑剂处置，并根据储层地质特征通知行业/政府管理压裂。
