Abstract A comparative analysis on source rock properties has been carried out the Miocene-Pliocene formations as well Quaternary terrace deposits using Rock–Eval pyrolysis results and organic petrography some biomarkers results. Samples were obtained from outcrops of deposits, Pliocene-aged Liang Formation together with Miocene Miri Setap Shale in Brunei-Muara district, sample lithologies rang...

Abstract In this study the hydrocarbon generation potential of coal and coaly shale samples collected from mines in Attock-Cherat Range Pakistan is optically analytically evaluated. These samples, representing Paleocene Hangu Formation, are analyzed across a range thermal maturity stages to understand their potential. The visual examination maceral type values vitrinite reflectance have been co...

BACKGROUND Pyrolysis of slaughterhouse waste could promote more sustainable phosphorus (P) usage through the development of alternative P fertilizers. This study investigated how pyrolysis temperature (220, 350, 550 and 750 °C), rendering before pyrolysis, and wood or corn biomass additions affect P chemistry in bone char, plant availability, and its potential as P fertilizer. RESULTS Linear ...

Characterizing the origin of natural fractures in organic-rich fine-grained deposits is key to constraining permeability evolution these potential source rocks and tight reservoirs, as well assess hydraulic connectivity fluid systems which they develop. Differently oriented calcite-filled (i.e. veins), hosted by mudrocks Lower-Middle Triassic Montney-Doig unconventional resource play (Western C...

In this paper, we report the pyrolysis and formation of magnetic minerals in three source rock samples from the Wessex Basin in Dorset, southern England. The experimental conditions in the laboratory recreated the catagenesis environment of oil source rocks. Magnetic analysis of both the heated and the unheated samples at room temperature and at very low-temperatures (5 K), coupled with transmi...

This study investigates the role of zooclasts in bulk organic matter composition, kerogen type, and hydrocarbon generation potential lower Paleozoic marine Alum shale Baltoscandia, northwestern Europe. The results show that graptolite periderm is composed non-granular cuticles granular filling. cuticle non-fluorescing has a well-polishing measurable surface, while fraction semi-translucent brow...

Chemometric methods can enhance geochemical interpretations, especially when working with large datasets. With this aim, exploratory hierarchical cluster analysis (HCA) and principal component analysis (PCA) methods are used herein to study the bulk pyrolysis parameters of 534 samples from the Persian Gulf basin. These methods are powerful techniques for identifying the patterns of variations i...
