This project aims to develop experimentally verified models for designing and monitoring of hydraulic fractures with constricted openings, to ensure adequate and robust hydraulic fracture control for example in petroleum production. Hydraulic fractures are often constricted by bridges that hold two sides of the fracture together. Failure to account for bridges and constriction of fractures can lead to premature screen-out (exceeding available pump pressure) of proppant and inadequate fracking control. The project results are expected to substantially increase the accuracy of design and monitoring of fracture opening, geometry and fluid flow to improve efficiency, safety and environmental security of the resource and energy extraction.

该项目旨在开发经过实验验证的模型，用于设计和监测具有狭窄开口的水力裂缝，以确保在石油生产中充分和稳健的水力裂缝控制。水力裂缝通常由将裂缝两侧连接在一起的桥梁收缩。如果不考虑桥和裂缝的收缩，可能会导致支撑剂过早筛出（超过泵的可用压力）和压裂控制不足。该项目成果有望大幅提高裂缝开度、几何形状和流体流动设计和监测的准确性，从而提高资源和能源开采的效率、安全性和环境安全性。
