Subsurface reservoir models have a high degree of uncertainty regarding reservoir geometry and structure. A range of conceptual models should therefore be generated to explore how fluids-in-place, reservoir dynamics, and development decisions are affected by such uncertainty. The rapid reservoir modelling (RRM) workflow has been developed to prototype reservoir models across scales and test their dynamic behaviour. RRM complements existing workflows in that conceptual models can be prototyped, explored, compared, and ranked rapidly prior to detailed reservoir modelling. Reservoir geology is sketched in 2D with geological operators and translated in real-time into geologically correct 3D models. Flow diagnostics provide quantitative information for these reservoir model prototypes about their static and dynamic behaviours. A tracing algorithm is reviewed and implemented to compute time-of-flight and tracer concentrations efficiently on unstructured grids. Numerical well testing (NWT) is adopted in RRM to further interrogate the reservoir model. A new edge-based fast marching method is developed and implemented to solve the diffusive time-of-flight for approximating pressure transients efficiently on unstructured tetrahedral meshes. We demonstrate that an implementation of the workflow consisting of integrated sketch-based interface modelling, unstructured mesh generation, flow diagnostics, and numerical well testing is possible.

非结构四面体网格的快速流动计算方法，用于快速油藏建模

地下储层模型对于储层的几何形状和结构具有高度的不确定性。因此，应生成一系列概念模型，以探讨这种不确定性如何影响就地流体，储层动力学和开发决策。快速储层建模（RRM）工作流程已开发为跨各个规模对储层模型进行原型设计并测试其动态行为。RRM补充了现有的工作流程，因为在进行详细的油藏建模之前，可以对概念模型进行原型设计，探索，比较和排名。利用地质算子以2D方式绘制储层地质，并将其实时转换为地质上正确的3D模型。流量诊断为这些油藏模型原型的静态和动态行为提供了定量信息。审查并实施了一种跟踪算法，以在非结构化网格上有效地计算飞行时间和示踪剂浓度。RRM中采用了数值井测试（NWT），以进一步探究储层模型。开发并实施了一种新的基于边缘的快速行进方法，以解决漫射飞行时间，以有效地逼近非结构化四面体网格上的压力瞬变。我们证明，实现由集成的基于草图的界面建模，非结构化网格生成，流量诊断和数值试井组成的工作流程是可能的。开发并实施了一种新的基于边缘的快速行进方法，以解决漫射飞行时间，以有效地逼近非结构化四面体网格上的压力瞬变。我们证明了实现由集成的基于草图的界面建模，非结构化网格生成，流量诊断和数值试井组成的工作流的实现是可能的。开发并实施了一种新的基于边缘的快速行进方法，以解决漫射飞行时间，以有效地逼近非结构化四面体网格上的压力瞬变。我们证明了实现由集成的基于草图的界面建模，非结构化网格生成，流量诊断和数值试井组成的工作流的实现是可能的。
