The Barnett Shale is of Mississippian age and of marine origin (similar to the Upper Alum Shale). Organic matter from the Barnett Shale generates about 30% gas in the oil window from primary cracking based on laboratory experiments (Jarvie et al., 2003). The Woodford Shale occurs in the Lower Mississippian/Upper Devonian and is also of marine ...Causal inference in complex systems has been largely promoted by the proposal of some advanced temporal causation models. However, temporal models have serious limitations when time series data are not available or present insignificant variations, which causes a common challenge for earth system science.5503.
