Dec 1, 2002 · The maturation characteristics of coaly source rocks are fundamentally different to those of marine and lacustrine rocks, and warrant separate guidelines for Rock-Eval-based assessment of their petroleum generative potential and thermal maturity.

Triassic and Jurassic sandstone plays charged from coaly Middle Jurassic source rocks have proven to be economically viable in the North Sea.

sediments. The main source rocks, especially within west Balingian, are coals of a lower coastal plain setting (Mazlan and Abolins, 1999). Towards the east, the source rocks are reported to become increasingly marine-influenced and increasingly gas-prone. For a thorough review on the exploration history and the petroleum system of this province,

Mar 1, 2021 · Coaly facies (coals, shaly coals and coaly mudstones) are the primary source rock in several important petroleum basins in SE Asia and Australasia. Delineating these facies and quantifying their organic richness within kitchen areas are some of …

Feb 1, 2019 · This study derives the kerogen type, thermal maturities, and hydrocarbon generating potential of the Carboniferous source rocks from the geochemical and organic petrological data of 146 source rock samples from 20 wells.

These results demonstrate that the coaly source rocks are dominated by vitrinite macerals with a relatively higher content of liptinite macerals, especially resinite, and these source rocks are more prone to both total hydrocarbon and liquid hydrocarbon generation.

Feb 8, 2022 · Carboniferous–Permian coaly source rocks deposited in North China were investigated using organic–inorganic chemistry, organic petrology, and biomarkers to analyze their hydrocarbon generation potential, maceral components, and depositional environments.

Mar 13, 2018 · The coaly source rock of the Middle Jurassic petroleum system in the greater North Sea is included in the Bryne/Lulu Formations (in Denmark), the Pentland Formation (in the UK), and the Sleipner and Hugin Formations in Norway.

Mar 19, 2020 · The coaly source rocks from the Pinghu Formation in the Xihu Sag have relatively high values of effective HI, which ranges from 167 to 281 mg HC/g TOC (mean 223.5 mg HC/g TOC). Rock-Eval and optical microscopic evaluation results suggest that the coals in the Xihu Sag belong to type II organic matter.

Coaly source rocks deposited in a paralic-deltaic environment are noteworthy potential oil and gas reservoirs. This study aims to contribute to the optimiza-tion of conventional oil and gas exploration through an understanding of the general char …
