Development of an Enhanced Numerical Modelling Visualization (NMV) Approach for Wellbore Stability Mechanisms

复杂三维数据的可视化是利益攸关方成功参与和传播/管理地球科学数据的重要组成部分。例如，井眼稳定性的评估需要了解下伏地质的复杂相互作用、宿主岩石的断裂力学以及在开采油气藏过程中不断变化的应力重新分布的不利影响。这项研究将利用钻孔数据的数字重建和结合钻孔失稳机理的三维数值模拟来展示虚拟和增强现实(VR和AR)的创新使用如何提供更好的可视化，并增强对控制深部钻孔围岩变形和破坏的复杂现象的理解。该项目通过对案例研究数据的分析，将为通过虚拟环境记录和交流模拟结果提供新的方法，突出应力引起的井壁破坏演变所造成的空间和时间变化。AR和VR平台提供了易于分发的文件格式，可供广泛的利益相关者在动态环境中从任何角度探索虚拟空间中的数据时使用。

Visualization of complex three-dimensional data is an important part of successful stakeholder engagement and dissemination/management of geoscientific data. For example, evaluation of borehole stability requires an understanding of the complex interaction of the underlying geology, fracture mechanics of the host rock mass and the detrimental effects of the changing stress redistribution during extraction of the hydrocarbon reservoir. This research will utilize digital reconstruction of borehole data and incorporation of three-dimensional numerical modelling of borehole instability mechanisms to demonstrate how innovative use of both virtual and augmented reality (VR and AR) can provide improved visualization and enhanced understanding of complex phenomena controlling deformation and failure of rock surrounding a borehole at depth. The project, through analysis of case study data, will provide new approaches for documentation and communication of modelled results through a virtual environment, highlighting spatial and temporal changes resulting from evolution of stress induced wellbore failure. AR and VR platforms provide easily distributed file formats that can be used by a wide range of stakeholders exploring the data in virtual space, from any angle, in a dynamic environment.
