Triaromatic steroid maturity

Phase fractionated condensates and oils from Haltenbanken have an effect on the gross composition, GOR and API of the petroleums (Karlsen et al. 1995). The ratio of hopanes to steranes, triaromatic steroid maturity parameters, and, in extreme cases, also the Pr/Ph, Pr/ -C)7 and Ph/ -C 8 ratios and the carbon isotope values are altered by this effect (Karlsen et al. 1995). The effect on the latter is due to... [Pg.345]

Figure 4 Distribution of triaromatic steroids (68) in GC-MS m/z = 231 selected ion chromatograms in (a) a Phanerozoic oil of low thermal maturity, (b) a mature Phanerozoic oil, and (c) an overmature bitumen from the late Archaean Fortescue Group in Western Australia. The inset in (c) is a 20 X magnification of the elution range of C26 to C28 triaromatic steroids (68b) (Brocks et ah, 2003a,b) (reproduced by permission of Elsevier...
