P-046 Characterization of the source rock of Jurassic (Tithonian) in Southeastern Mexico applying the organic facies Jose Antonio Perez Ortiz 1 , Luis Lopez Lopez 1 , Esaul Gutierrez Mejia 1 , Luis Manuel Medrano Morales 2 1 Instituto Mexicano del Petroleo, Pachuca, Mexico, 2 Petroleos Mexicanos, Cd. del Carmen, Mexico (corresponding author:jortiz@imp.mx) We performed optical-geochemical study of 10 wells located in the Southeastern Mexico Basins in order to make a correlation of organic facies. The wells studied they are located in the marine region, the call Sonda of Campeche, where the carbonated rocks, they are rich in organic matter laminated of algal-sapropelic and ligneous type. In Sonda of Campeche, in which to the Upper Jurassic it corresponds, we can mention that are rocks of Tithonian age, which are represented by calcareous argillaceous limestones and shales; with an irregular distribution rocks of Kimmeridgian age, composed by fine terrigenous horizons and micritic carbonates. Finally we can indicate rocks of Oxfordian age, where some associate fine terrigenous horizons with evaporítes Optical and geochemical characterization studies were made in order to know whether these are source or reservoir facies. We studied 250 samples of core and 25 oil samples from these 10 wells. Geochemical studies were applied to these samples: - Gas Chromatography - Saturated biomarkers - Diamondoids - Pyrolysis - Compositional kinetic - Carbon isotopy While optical analysis the samples were made: - Transmitted Light - Fluorescent Light - Reflected Light - Confocal Study The analysis of reflected light allowed to know the range of maturity of organic matter and studies with confocal microscopy were performed to correlate the oils with organic facies. Thanks to the findings and conclusions of this study, largely eliminated the geological and economic risk, as recommended and prevented the drilling of new wells in areas of low maturity of organic matter. In addition, this study allowed to know and characterization of oils in relation to the organic facies and characterize mixtures of oils 193
P-047 Characterization of lignites from the Drmno field, Kostolac Basin, Serbia, based on biomarker composition Dragana Ņivotiš 1 , Ksenija Stojanoviš 2 , Aleksandra Ńajnoviš 3 , Olga Cvetkoviš 3 , Hans Peter Nytoft 4 , Georg Scheeder 5 1 University of Belgrade, Faculty of Mining and Geology, 1100 Belgrade, Serbia, 2 University of Belgrade, Faculty of Chemistry, 11000 Belgrade, Serbia, 3 Center of Chemistry, IChTM, 11000 Belgrade, Serbia, 4 Geological Survey of Denmark and Greenland, DK-1350 Copenhagen, Denmark, 5 Federal Institute for Geosciences and Natural Resources, 30655 Hannover, Germany (corresponding author:xenasyu@yahoo.com) The Kostolac lignite basin of Upper Miocene age is located about 90 km east of Belgrade. It is divided into three coal fields: Drmno in the eastern, Širikovac in the central, and Smederevsko Podunavlje in the western part of the basin. Coal from the Drmno field is typical humic coal with huminite concentrations between 50.8 and 90.3 vol.%, liptinite less than 6 vol.% and inertinite between 1.5 and 21.6 vol.%. Saturated and aromatic hydrocarbons were analyzed by GC-MS. The relative proportions of hydrocarbons in the SOM are low (< 11 %), consistent with the low maturity of the organic matter. The n-alkane patterns of the coal samples are dominated by long-chain nalkanes (C27-C33) with a marked odd over even predominance (CPI 3.1-5.6), indicating a significant contribution of epicuticular waxes. The pristane/phytane (Pr/Ph) ratio varies in range 0.24 to 1.74. Based on the maceral composition, it could be concluded that Pr and Ph most probably originated from chlorophyll in land plant-dominated organic matter. Therefore, the values of Pr/Ph could imply anaerobic to slightly oxic conditions during sedimentation, consistent with maceral composition. In all samples, aromatic sesquiterpenes are observed in low quantities. Cadalene predominates over cuparene, calamenene and 5,6,7,8-tetrahydrocadalene. Diterpenoids are main constituents of saturated and aromatic fractions of investigated coals. 16�(H)-phyllocladane and pimarane are dominant by far in the saturated fractions, whereas norpimarane, kaurane and beyerane are present in minor amounts. The aromatic diterpenoids consist of norabietatetraenes, norabieta-trienes, dehydroabietane, bisnorsimonellite simonellite, retene, sempervirane, totarane, bisnordehydroabietane, hibaene, ferruginol, with 18-norabieta-triene, dehydroabietane, simonellite and retene predominating. Due to the fact that in all samples totarane was identified, the precursor of which is totarol [1], it was assumed that ferruginol, 18norferruginol and 12-hydroxysimonellite may be subjected to the same diagenetic transformations as totarol, specially in anoxic conditions, forming dehydroabietane, 18-norabieta-triene and simonellite, which are dominant compounds in aromatic fraction (Fig. 1). Almost all of the samples contain nonhopanoid triterpenoids in very low amounts, consisting of de-A-ring degraded triterpenoids (des-Aolean-enes, des-A-urs-enes, des-A-lupane, tetramethyl-octahydro-chrysenes and trimethyltetrahydro-chrysenes). Strong domination of diterpenoids over triterpenoids implies that the coalforming plants were mostly gymnosperms (conifers). A high amount of 16α(H)-phyllocladane and presence of pimarane, ferruginol, totarane, hibaene, and cuparene indicates that the coal forming plants belonged to the conifer families Taxodiaceae, Podocarpaceae, Cupressaceae, Araucariaceae and Phyllocladaceae [1,2]. The hopanoid patterns are characterized by the occurrence of C2713,18-hop-ene, 17α,21β(H)- and 17β,21β(H)- hopanes from C27 to C32 with the C28 being absent. Domination of ββ-isomers in range C27 - C30 over αβ-hopanes confirms an immature stage of the organic matter. Steroid biomarkers in Drmno samples consist of C29 Δ 2 -, Δ 4 - and Δ 5 -sterenes. Low steroids/hopanoids ratio (0.07-0.22) indicates a more bacteria-influenced facies and argues the role of bacteria in degradation of plant tissue. Fig. 1.
