Integrated Subsurface Carbon Sequestration and Enhanced Coalbed Natural Gas Recovery Using Cement Kiln Emissions, Wilson County, Kansas

Depositional Setting

Depositional setting is a key control of coal distribution, thickness, and coal quality. A continuous core from Wilson County was used to collect coal samples and to help identify lithotypes within the study area. The core was described and broken into 10 lithofacies. Interpretations into processes and environments were made. A variety of depositional settings were determined, ranging from subaerial exposure to deep-water environments. The distribution and occurrence of lithofacies within the Cherokee and Marmaton groups indicates cyclic fluctuations in relative sea level. The following table outlines the facies, processes, and environments found in the Cherokee and Marmaton groups in the study area.
