This paper reviews the significance of solid bitumen with emphasis on source-rock
reservoirs. We discuss difficulties and discrepancies with terminology, especially those …

Organic petrology developed as coal petrology at the beginning of the 20th century
dedicated mainly to the study of coals because of their utilization in industry. Coal petrology …

Petrographic and organic geochemical analyses on solid reservoir bitumen from the Late
Precambrian to Early Cambrian Ara Group indicate polyphase thermal evolution in the …

Petroleum geochemistry improves exploration efficiency by accounting for many of the
variables that control the volumes of crude oil and natural gas available for entrapment …

This review examines the history and current practice of technologies for imaging of pores in
sedimentary rocks. Pores are that portion of the rock volume occupied by components of …

Thermal maturity is critical to evaluate petroleum systems and to interpret biomarker results
for paleoenvironmental and geobiology studies. Many thermal maturity indices were …

The tight reservoir of the Lucaogou Formation in the Jimsar sag, located in the southeastern
Junggar Basin, northwest China, has been investigated for its great potential tight oil …

After 35 years of exploration, creaming of the conventional plays in Oman is nearly
complete, and consequently, the search has commenced for new, less obvious plays. Many …

Hydrocarbon evolution is extremely challenging to determine, both temporally and spatially,
in complex tectonic settings. Here we investigate the western margin of the Xuefeng uplift …

Shale is now commonly exploited as a hydrocarbon resource. Due to the high degree of
geochemical and petrophysical heterogeneity both between shale reservoirs and within a …
