SKU: GRI-00/0158
Hydrogeochemistry of the New Albany Shale, Illinois Basin. Phase III

This research project investigated gas occurrence and production from the New Albany Shale, a Devonian black shale of equivalent age to the Antrim Shale, Michigan Basin. Exploration focused on the eastern basin margin, with the expectation that microbial gas would be associated with freshwater recharge.

Summary:
This research project investigated gas occurrence and production from the New Albany Shale, a Devonian black shale of equivalent age to the Antrim Shale, Michigan Basin. Exploration focused on the eastern basin margin, with the expectation that microbial gas would be associated with freshwater recharge. Compositions of formation water and casing gas samples, as well as core gases, were determined. Although the New Albany Shale is both organic-rich and extensively fractured, hydrostratigraphic relations limit the invasion of meteoric water locally. The New Albany Shale is confined by the overlying Borden Group, a thick aquitard. Patterns of formation water salinity and gas chemistry reveal that meteoric water entered the shale from underlying Devonian carbonate aquifers, except in a small area where porous Mississippian carbonates directly overlie the shale. These factors produced an irregular production pattern and also led to unacceptably high water production rates when confined aquifers were tapped. Gas associated with these recharge areas is a mix of microbial and thermogenic. Deeper basin drilling targets produce small volumes of highly saline water and only thermogenic gas.
