Pore evolution characteristic of shale in the Longmaxi Formation, Sichuan Basin

Petroleum Research, 2017
Through the field emission scanning electronic microscope (FESEM) and the nitrogen adsorption test, pore type and structure of shale reservoir in the Longmaxi Formation in the Sichuan Basin were well studied. Result showed that the pore type includes organic pore, intercrystalline pore, dissolution intracrystalline pore and interparticle pore, and the ...

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Reservoir diagenesis research of Silurian Longmaxi Formation in Sichuan Basin, China

Journal of Natural Gas Geoscience, 2016
AbstractThe reservoir diagenesis of Silurian Longmaxi Formation in Sichuan Basin was studied based on a large number of thin section identification, scanning electron microscopy analysis, X-ray diffraction tests, and some other experiments. Seven diagenetic processes were identified, including compaction, cementation, clay mineral transformation ...
