Petroleum generation by laboratory-scale pyrolysis over six years simulating conditions in a subsiding basin

Transition metal catalysis in the generation of petroleum and natural gas. Final report, September 1, 1992--October 31, 1995

“…of Interior database (Hamak and Sigler, 1991). The horizontal lines indicate the compositional regions for gas products from the indicated processes: Oil & SR Pyrolysis: taken from reported products of oil and kerogen pyrolysis experiments (Horsfield et al, 1991;Espitalie et al, 1987;Saxby and Riley, 1984;Evans and Felbeck, 1983;McNab et ai., 1952). SR Catalysis: from experiments using a Monterey source rock (Miocene) described in Mango et al,(1 994).…”

“…Disturbing contradictions exist, however: oil is found at great depth, at temperatures where only gas should exist (Price, 1993) and oil and gas deposits show no evidence of the thermolytic debris indicative of oil decomposing to gas (Mango, 1987). Moreover, oil and kerogen pyrolysis typically produces between 10 and 60% wt methane (in C&) (Horsfield et al, 1991;Hikita et al, 1989;Espitalie et al, 1987;Saxby and Riley, 1984;Evens and Felbeck, 1983;McNab et al, 1952) while natural gas contains between 60 and 95+ 'YO methane (Hamak and Sigler, 1991). n-Alkanes give 6 and 13 % methane at 600 and 7OO0C, respectively (Fabuss et al, 1962;Appleby et al, 1947).…”

Long-chain aliphatic nitriles in pyrolysates of young kerogen: implications for the intermediates in petroleum hydrocarbon formation.

“…This type of experiment is one of the more useful approaches to elucidating the chemistry of petroleum genesis, although it has been often criticized because of its completely different time-temperature relationship as compared with geological processes (Durand 1983;Ishiwatari et al 1976Ishiwatari et al , 1977Ishiwatari and Fukushima 1979;Saxby et al 1986;Saxby and Riley 1984;Tegelaar et al 1989).…”
