“…The preferential 93 expulsion of aliphatic over aromatic hydrocarbons 94 was first noted by Baker (1962). A preferential expul-95 sion sequence (saturated hydrocarbons > aromatic 96 hydrocarbons > polar compounds), i.e., chemical frac-97 tionation because of the polarity of compounds, was 98 proposed by Leythaeuser et al (1988a) Lafargue et al (1990) and Sandvik et al (1992), and 102 eventually theoretically modeled by Ritter (2003) and 103 Kelemen et al (2006). A preferential expulsion of 104 smaller molecular size components over larger ones, 105 i.e., physical fractionation, has also been documented 106 as having taken place (Mackenzie et al, 1983; 107 Leythaeuser et al, 1984), though the phenomenon is 108 not always readily discernable (Leythaeuser et al,109 1988c; Eseme et al, 2007).…”

9 The Marathon 1 Mesquite well was drilled in Hamilton County, 10 Texas, targeting the Barnett Shale with late oil window maturity. 11 Combining a large suite of petrologic and high-resolution organic 12 geochemical analyses on 120 core samples, we have been able to 13 document qualitatively and quantitatively the effects of petroleum 14 retention and expulsion within and from five intervals within the 15 Barnett Shale. Lithological heterogeneities control the composi-16 tion and amount of retained fluids; the sorption of oil by solid 17 organic matter is important in all intervals. Applying empirical 18 formulas, we have been able to demonstrate not only that retention 19 is primarily controlled by total organic carbon (TOC), but also 20 that the "live" or "labile" component, rather than "dead" or "inert" 21 carbon, constitutes the most active sorptive sites. Additional reten-22 tion in the micropores provided by biogenic microcrystalline 23 quartz (sponge spicules) accounts for the sweet spot defined by 24 an "oil crossover" in the 914-m (30-ft) thick second interval. The 25 fluorescing oil occurring in the axial chamber of the sponge spic-26 ules and that sorbed on organic particles are together enriched in 27 saturated hydrocarbons, whereas the dispersed oil from the adja-28 cent interval 3 is depleted in this compound class. Mass-balance 29 calculations reveal that short-distance migration of petroleum into 30 this "reservoir" interval (second) fractionates the generated oil 31 into a higher quality oil by preferential retention in the order polar 32 compounds > aromatic hydrocarbons > saturated hydrocarbons 33 within the underlying organic matter and clay-rich third interval This has to be remedied because even subtle changes in bulk fluid M51South Africa, China, Australia, and North M52Africa are key activities in service and M53research at the present time.We wish to thank D. M. Jarvie and R. J. Hill M56for their careful reviews and helpful M57comments. The editorial comments and M58suggestions by Terrilyn Olson are also M59gratefully acknowledged. Parts of this study M60were carried out during the course of the M61"GASH-Gas Shales in Europe" initiative. The M62authors wish to thank the sponsors of this M63project, especially Marathon Petroleum M64Corporation, for providing sample material. M65We are also grateful to Prof. (Bowker, 2007;Jarvie et al., 2007; Bunting and 139 Breyer, 2012) as well as in reservoir diagenesis 140 (Milliken et al., 2012 (Bowker, 2003). Rather than detrital quartz, micro-147 crystalline quartz is the major component of the sili-148 ceous Barnett facies (Loucks and Ruppel, 2007). 149 Milliken et al. (2007) interpreted the microcrystalline 150 quartz in Barnett Shale as being derived from mainly 151 agglutinated foraminifera, whereas others have 152 emphasized the importance of siliceous sponge spic-153 ules (Hickey and Henk, 2007; Slatt and O Brien, 154 2011; Abouelresh and Slatt, 2012). 155 In this paper, we (1) assess the amount and quality 156 of retained hydr...

“…partial resins and asphaltenes, were not included in the S1 values due to their relatively high stability and boiling point. Experimental simulation and kerogen swelling data has indicated that oil expulsion results in richer resins and asphaltenes in the residual bitumen than in the expelled oil (Kelemen et al, 2006a;Lafargue et al, 1990Lafargue et al, , 1994Ritter, 2003;Sandvik et al, 1992). Delvaux et al (1990) used the comparative Rock-Eval analysis of solvent-extrated and unextracted rocks to allow a better estimating of total bitumen content based on the pyrolysis data.…”

“…Many methods exist for the study of the expulsion characteristics of source rocks (Magara, 1986;Lafargue et al, 1990;Xu et al, 1995;Lu et al, 2000). These can be classified into three main types: (1) models based on thermal simulation experiments, (2) the chemical dynamics method based on chemical reactions, and (3) the material balance method based on substance conservation.…”
