Sequence Stratigraphy and 3-D Reservoir Characterization of the Ray Reef, Macomb County, Michigan
Western Michigan University Department of Geosciences Kalamazoo, MI
The Michigan Basin Silurian pinnacle reefs are known oil and gas reservoirs. A fully integrated sequence stratigraphy based study including modern reservoir characteristic analogs, 3-D modeling, subsurface core analysis, and wireline logs has never been done in the reservoirs in the Michigan Basin. The purpose of this study is to enhance the knowledge and understanding of Silurian carbonate reef facies to apply to predicting reservoir quality with emphasis on the Ray Reef, Macomb County, Michigan. The ability to predict reservoir characteristics, identify facies variability, and establish a sequence framework is a significant tool when producing hydrocarbons from carbonate rocks. Subsurface cores, facies analysis, well logs, and petrographical analyses will be incorporated to produce a 3-D model of the reef which can be used to define reef variability and architecture to predict reservoir characteristics. This research will result in knowledge of structure and evolution of these Silurian reefs in the southern Michigan trend that will produce enhanced understanding of reservoir distribution and performance.
