Application of mapping and dating techniques in the study of ancient carbonate reservoirs: A case study of Sinian Qigebrak Formation in northwestern Tarim Basin, NW China

Petroleum Exploration and Development, 2020
Ancient marine carbonates experienced complex modifications, making it difficult to identify reservoir genesis and effective porosity before hydrocarbon migration.

Factors affecting metal mobilisation during oxidation of sulphidic, sandy wetland substrates [PDF]

, 2010
Most metals accumulate as sulphides under anoxic conditions in wetland substrates, reducing their bioavailability due to the solubility of metal sulphides. However, upon oxidation of these sulphides when the substrate is occasionally oxidised, metals can

Reservoir characteristics and genesis of the Lower Ordovician Tongzi Formation in central Sichuan Basin, China

Frontiers in Earth Science, 2023
Although the Ordovician petroleum exploration in the Sichuan Basin has been developed slowly for a long time, deepening the research of reservoir characteristics and genesis is still a robust way to accelerate it.

Long-time evolution of sequestered CO$_2$ in porous media [PDF]

, 2014
CO$_2$ sequestration in subsurface reservoirs is important for limiting atmospheric CO$_2$ concentrations. However, a complete physical picture able to predict the structure developing within the porous medium is lacking.
