Study Highlights

Summary

This study of the Ordovician sandstones of the Michigan Basin is designed to assist exploration and production geologists in their understanding of factors that control hydrocarbon distribution and production in these reservoirs.

Exploration for Ordovician sandstone reservoirs in the Michigan Basin has been primarily a structural play. However, recent drilling has shown that numerous other stratigraphic intervals are potentially productive.

This report documents the role of depositional and diagenetic systems in defining the distribution of porous reservoir sandstones. Geological, petrophysical, and engineering characteristics for several fields are combined into field studies to document reservoir characteristics, drive systems and production potentials. This provides valuable analogs for future exploration and development.

The study covers 54,000 square miles, within which 437 wells were correlated, and represents six man-years of geologic research.
