Abstract
The New Albany Shale in the Illinois Basin is a Middle and Upper Devonian to Lower Mississippian unit correlative with the Antrim Shale of the Michigan Basin and the Ohio and Marcellus shales of the Appalachian Basin. These shale units are thought to be part of an epicontinental succession deposited in response to a sea-level rise over large areas of the North American craton, and they are important targets for recent unconventional gas and oil shale developments.The New Albany Shale is org. matter rich kerogen Type II sequence spanning a thermal maturity range corresponding to vitrinite reflectance (Ro) values 0.5% and lower close to the basin margins to 1.5 % in the southern part of the basin in Illinois. The presence of gas in the New Albany Shale sparked continued industrial interest since the late 1800s. It has been also well documented that the New Albany Shale is the source of the majority of oil produced in the Illinois Basin.This study re-examines geol. and reservoir properties of the New Albany Shale as a potential liqs.-from-shale play in the Illinois Basin. Data on org. matter content and maturity will be discussed to understand the hydrocarbon generative potential and quality of the generated hydrocarbons. Geochem. data in combination with depth and pressure will be used to suggest best targets for in-place liq. hydrocarbons in the basin. Applicability of gas prodn. experiences to potential unconventional oil prodn. will also be discussed. on SciFinder(R)]
