Silurian (Niagaran) reefs are significant hydrocarbon reservoirs in the Michigan Basin, having produced nearly 470 MMBO and 2.75 trillion cubic feet of gas. Detailed facies analysis of the Belle River Mills Silurian reef indicates that a correlation may exist between depositional facies and permeability values. Sequence stratigraphic analysis conducted on cores revealed 3 fourth-order high frequency sequences, seen consistently throughout the reef. Schlumberger's Petrel modeling software was used to generate 3-D facies and petrophysical models as a means of enhancing the understanding, and possible controlling mechanisms, of reservoir property distribution in the BRM reef.
Results reveal a well-developed windward geometry at the east/southeast margin of the reservoir, with an increase in porosity and permeability distribution along the eastern section of the reef. Identification of the sequence stratigraphic framework and correlations between detailed facies and reservoir quality can enhance primary and secondary production in these reservoirs by increasing the visualization and understanding of the reservoir's internal architecture.
