Mt. Simon Sandstone, Illite, Diagenesis, geologic carbon storage, Diagenesis, Illite, Mt. Simon Sandstone, geologic carbon storage
Anthropogenic greenhouse gases such as carbon dioxide (C02) must be mitigated and reduced to preserve a stable climate for future generations. One promising technology is carbon capture and storage (CCS) in geologic formations, which is currently being deployed in numerous pilot projects across the United States. One of these is the Illinois Basin–Decatur Project that has successfully stored 1 million metric tons of C02 in the Mt. Simon storage complex. The Mt. Simon Sandstone reservoir has been largely unexplored due to a previous lack of economic interest. Oil-bearing formations in the Illinois Basin are in younger successions and formation waters in the Mt. Simon are highly saline but with low levels of critical elements (i.e. lithium, magnesium). In the Illinois Basin, a limited number of drill holes penetrate the Mt. Simon formation with an even smaller number of core samples in these deep strata. This has left the earliest Paleozoic rocks in the Illinois Basin poorly understood. The stratigraphic test well at the IBDP revealed the lowest most section of the Mt. Simon to be a thick highly porous and permeable sandstone. With a near to complete lack of other wells penetrating this lower Mt. Simon unit, major questions arose such as 1) what is the origin of this deep porous sandstone; 2) what controls the distribution of this sandstone and where can more of it be found; 3) what controls porosity at this depth when overlying sandstones have largely poor reservoir ...
