Figure 7. Sterane [5α, 14β, 17β (20S), mass-to-charge ratio 218] distributions. The EQT 504353 label refers to the six solvent extract analyses from the downdip high-maturity EQT 504353 well. Average Berea- and Ohio Shale–reservoired (n = 23) and lower Paleozoic–reservoired (n = 34) oil from eastern (E.) Ohio shown for comparison using data from GeoMark (2015). Modified from Parris et al.
