1-30 (source unit).Furthermore, molecular fractionation, i.e., a preferential expulsion of lower weight hydrocarbons (n-alkanes) could be calculated.An additional practical result for source rock assessment is that corrected S2 (petroleum generated by pyrolysis) and TOC values should calculated combining Rock-Eval pyrolysis data on whole rocks following Soxhlet extraction.Using parameters based unextracted only, the petroleum systematically overestimated degree kerogen conversion is,...
Petroleum is retained in shales either a sorbed state or free form within pores and fractures.In with oil resource potential, organic matter properties (i.e.richness, quality thermal maturity) control retention general.In gas shales, govern occurrence.While some may originate via secondary cracking reactions, it still largely unclear as to how these originate.Here, we present case histories mainly for two classic the Barnett Shale (Texas, USA) Posidonia (Germany).In both cases, shale...
The primary migration of petroleum has been recently described in detail for a thermally mature core the Barnett Shale with almost nonvariant organofacies and maturity. Here, we use samples from same well to provide new insights into fractionation pyrrolic nitrogen compounds during migration. Using gas chromatography–mass spectrometry (GC-MS), decrease concentration carbazoles benzocarbazoles was observed which correlated distance. However, preferential removal individual isomers like...
This paper clarifies the controls of oil retention in Niobrara Formation, Denver Basin, western United States.Sweet spots have been recognized using a total 98 core samples from 5 wells with maturities covering window.Oil source rock (carbonate content <70 wt.%) is controlled by organic matter richness and thermal maturity.In general, vaporizable hydrocarbon (HC) yield at nominal temperatures 300°C (572°F) (Rock-Eval S 1 ) positively correlated to carbon (TOC).With increasing maturity,...
Carboxylic acids (CAs), common oxygen-containing compounds in petroleum samples, have been paid high attention several areas, including geochemistry, processing, and pollution research. This paper focuses on the overview of separation analysis CAs its geochemical significance. The first section describes those studies that aimed to separate enrich from extremely complex samples prior instrumental analysis. In second section, methods for identifying quantifying are discussed, which...
