Oil and gas production from tight hydrocarbon resources by drilling and completion of multilateral/multifractured horizontal wells is becoming a common practice in the North America. However, efficient, responsible, and sustainable development of such resources requires careful evaluation of massive hydraulic fracturing operations involved. The main concerns include 1) inefficient recovery of fracturing water, 2) high concentration of various salts in the produced water, and 3) lack of reliable models for characterizing the induced fracture network using the pressure, rate and concentration data measured during flowback operations.

在北美，通过多分支/多裂缝水平威尔斯井的钻井和完井从致密烃资源生产石油和天然气正在成为一种普遍的做法。然而，高效、负责任和可持续地开发这些资源需要仔细评估所涉及的大规模水力压裂作业。主要问题包括1）压裂水的回收效率低，2）采出水中各种盐的浓度高，以及3）缺乏用于使用返排操作期间测量的压力、速率和浓度数据来表征诱导裂缝网络的可靠模型。
