Abstract

Reservoir characterization of carbonate rocks is complicated by heterogeneous pore architecture related to primary depositional facies and subsequent diagenesis; this is especially true in diagenetically-altered and structurually-influenced Trenton-Black River reservoirs of the Michigan Basin. Accurate and reliable prediction of reservoir properties within hydrothermal dolomite reservoirs through the use of acoustic properties would aid exploration and characterization both within and outside of the Michigan Basin.

Results indicate that measures of pore architecture when integrated with measures of physical properties into multiple variable linear regression can accurately predict permeability of core plugs. However, due to the highly-heterogeneous distribution of pore architecture and resultant petrophysical properties, upscaling these relationships to wireline log or seismic scale is problematic.

Integrating modem borehole measures of physical properties and measures of pore architecture derived from cuttings data may increase the predictability of permeability within hydrothermal dolomite reservoirs.
