Geochemistry of petroleum systems in the Niuzhuang South Slope of Bohai Bay Basin: Part 3. Estimating hydrocarbon expulsion from the Shahejie formation

The effect of oil expulsion or retention on further thermal degradation of kerogen at the high maturity stage: A pyrolysis study of type II kerogen from Pingliang shale, China

“…The high oil expulsion efficiencies for type I and type II kerogen in the oil window were also validated by geological section studies in the Ordos Basin (Zhang et al, 2006) and Bohai Bay Basin (Pang et al, 2005). Meanwhile, the transformation ratio of oil from type I and II kerogen may reach 60% or more, as evidenced by many laboratory and field observations (Andresen et al, 1995;Pepper and Corvi, 1995;Behar et al, 1997;Lewan, 1997;Xiong et al, 2002;Pan et al, 2010;Lewan and Roy, 2011;Wei et al, 2012).…”

Source rock characteristics and hydrocarbon expulsion potential of the Middle Eocene Wenchang formation in the Huizhou depression, Pearl River Mouth basin, south China sea

“…The method used in this study was the hydrocarbon generation potential model proposed by Pang et al (2005) (Fig. 3).…”

“…Hydrocarbon expulsion occurs when the hydrocarbon generation potential decreases (Fig. 3;Pang et al, 2005;Guo et al, 2014), and the corresponding geological condition is defined as the hydrocarbon expulsion threshold (Zhou and Pang, 2002;Pang et al, 2005). Before hydrocarbons begin to be expelled, the hydrocarbon generation potential index is called the original hydrocarbon generation potential index (GPI o ) (Fig.…”

Evolution and Movement of Source Kitchens and Their Control of Oil and Gas in the Tarim Cratonic Basin, China

“…Quantitative predication of mixed oils should include linear or non-linear binary or ternary model utilizing hydrocarbons indices Jiang et al, 2002;Van Aarssen et al, 1999), carbon isotopic method Santos et al, 1999), experimental modeling and calculation of hydrocarbons expelled based on material balance principles (Pang et al, 2005). The former researchers have already got many qualitative and quantitative achievements in the aspects of oil and gas from which sets of source rocks, or two sets of source rocks, and mixed relative contribution amount (Shi et al, 2005;Liang et al, 2000;Zhang et al, 2000Zhang et al, , 2005Wang et al, 2008 andLi et al, 2009).…”

This paper studies hydrocarbon source kitchen controls on mixed crude oils based on material balance principles (Pang et al, 2005). (Table 2).…”
