Stratigraphic Distribution of Rogers City Dolomitization Across the West-Central Region of the Michigan Basin

E. T. Taylor
Independent Geologist, Traverse City, MI

Historically, the upper Dundee (Rogers City formation) has been an important oil and gas zone in the west-central portion of the Michigan Basin. Approximately 100 MMBO has been recovered from the 40 commercial Rogers City fields within this region. Primary geologic controls on production include structural uplift and adequate reservoir development at the top of the Dundee.

In west-central Michigan, the Rogers City carbonate interval exhibits two distinct lithotypes; regional dense limestone laterally abutting secondary dolomite. The superior oil production is associated with the dolomite facies as porosity and permeability development is greatly enhanced. Utilizing the existing well database, the dolomite facies can be mapped across this region as laterally extensive trends. Identification of these stratigraphic fairways provides important information for future hydrocarbon exploration. Maps exhibiting trends of Rogers City dolomitization will be displayed during the presentation.
