Rock typeExploration significanceOrdos BasinFor a long time, the Chang 73 sub-member of the Ordos Basin was mostly investigated as a single source rock, with hardly any investigation into the characteristics of various rock types or the integration of source and reservoir. Based on correlation ...
we systematically studied the geochemical and lithological characteristics, accumulation space types and their distribution patterns as well as reservoir physical properties in addition to the hydrocarbon source rock of the F2 and the F4
They are methods based on mineral constituents, rock strength properties, stress-strain characteristics, and energy balance analysis. The first two types are derived from parameters under no confining pressure. So, these methods could not consider the effect of confining pressure on brittleness and ...
Rock physics concepts are widely used to establish connections between rock compositions and macroscopic properties. A proper rock physics model can help effectively study the rock characteristics. As an unconventional resource, shale gas has recently received increasing attention. Many challenges have been...
Occurrence state and characteristics of organic matter in over-mature marine shale : a case study for the Lower Cambrian Niutitang Formation in Guizhou Pro... The black shale deposited in the Lower Cambrian Niutitang Formation in Guizhou is a favorable source of the rock. Taking the shale of...

For the other two blocks, the Changning Block is better than the Zhaotong Block. By comparing with the Mississippian Barnett shale, characteristics that are crucial for a high-yielding in the Sichuan Basin include a high content of organic matter (TOC>2.5%), a moderate thermal maturity (R...
3.1.2. Lithofacies characteristics of high-quality shale gas reservoir Shale gas is in organic-rich shale, and the fine division of shale rock types and lithofacies types is the foundation for determining high-quality reservoirs [6,22,23]. According to core observation, sheet identification, and...
