The Midwest Regional Carbon Sequestration Partnership has been investigating various reservoir characterization and modeling technologies as part of its commercial-scale implementation of carbon dioxide injection for geologic storage in multiple Silurian carbonate pinnacle reefs in northern Michigan, USA. This paper presents a discussion of the reservoir modeling study that was conducted for history-matching oil production and CO2 injection responses, forecasting CO2 plume migration and estimating associated storage to characterize the closed, depleted Dover-33 reef which has undergone extensive primary and secondary production. Dynamic modeling using equivalent simplified descriptions of reservoir heterogeneity were found to be numerically efficient and successfully explained the observed pressure buildup in the reef during the MRCSP CO2 injection phase. The validated history matched models are extremely useful for potential predictive modeling for considering operational optimization and evaluating subsequent production scenarios relevant to the reef.

动态模型,以了解贫瘠的尖峰礁储层中来自采油和注入CO 2的压力响应:使用简化的储层非均质分辨率手动校准

中西部地区碳固存伙伴关系一直在研究各种储层表征和建模技术,这是其在美国密歇根州北部志留系碳酸盐岩顶峰礁石中二氧化碳注入地质储存的商业规模实施的一部分。本文介绍了针对历史匹配的采油量和CO 2注入响应,预测CO 2进行的储层建模研究的讨论。羽流迁移并估算相关的储藏量,以表征已经历大量初级和次级生产的封闭,枯竭的Dover-33珊瑚礁。使用等效的简化描述的储层非均质性动态模型被发现在数值上是有效的,并且成功地解释了在MRCSP CO 2注入阶段在礁石中观察到的压力累积。经过验证的历史记录匹配模型对于潜在的预测模型非常有用,可以用于考虑运营优化和评估与珊瑚礁相关的后续生产方案。
