Depositional Facies And Sequence Stratigraphic Model For The Silurian Reefs, Michigan Basin, Usa, Zaid N. Nadhim

Masters Theses

Depositional models for the Silurian reefs in the Michigan Basin suggest that internal facies are either (i) randomly distributed within a symmetrical reef structure, or (ii) highly asymmetrical and strongly controlled by paleo-wind direction. To further test the applicability of these models, internal facies distributions were mapped using high-resolution core and log data in two sets of Silurian reefs. The results suggest that the relationship between reef geometry, facies distribution and proposed paleo-wind direction is more inconsistent than recently proposed. More specifically, facies descriptions from the Silurian reefs suggest the following. First, overall reef geometry and facies distributions are not …

Integrating Depositional Facies And Stratigraphy In Characterizing Hydrothermal Dolomite Reservoirs: Trenton Group Of The Albion-Scipio Trend, Michigan, Marcel R. Robinson

Masters Theses

Reservoir characterization of carbonate rocks requires understanding the role of depositional and diagenetic parameters in reservoir distribution. This is especially true for the diagenetically-altered and structurally-influenced Trenton-Black River reservoirs of the Michigan Basin. Evaluating the depositional evolution and reservoir characteristics of component depositional facies through modeling and stratigraphic reconstruction would aid in exploration and characterization through providing a prediction tool for reservoir distribution, both within and outside of the Michigan Basin.

Results indicate that reservoir development is controlled by primary rock fabric related to depositional facies. Depositional and stratigraphic reconstructions show facies distribution trends occur consistently and therefore predictably away …
