Advanced techniques for geostastical modeling considering complex geological features

确定准确的地质边界和区域对于任何应用于矿产或石油储量的数值模型的健全实施至关重要。复杂的地质环境是难以模拟的，但有许多基于地质沉积环境的技术可用。这项工作探索了对当前建模技术的一些改进，特别是多点统计（MPS）和基于对象/过程的建模（OBM），以在分类和连续变量地质统计模型中再现非常复杂的地质特征。这些改进将导致更准确的储层预测和改进储层管理决策。建模的好处在支持组织提供的许多实际油藏和矿床上得到了证明。

Determining accurate geological boundaries and domains is critical for a sound implementation of any numerical model applied to mineral or petroleum reserves. Complex geological environments are difficult to model but there are a number of techniques available based on the geological depositional environment. The work explores a number of improvements to current modeling techniques, specifically, multiple point statistics (MPS) and object/process based modeling (OBM) to reproduce very complex geological features in categorical and continuous variable geostatistical models. These improvements will lead to more accurate reservoir forecasting and improved reservoir management decision making. The benefit in modeling is demonstrated on a number of real reservoirs and deposits provided by the supporting organizations.
