Selecting appropriate hydraulic fracturing methods for wells in deep and tight fractured sandstone reservoirs

Deep Underground Science and Engineering, EarlyView.
Deep and tight sandstone reservoirs require hydraulic fracturing treatment to enhance production, even in the presence of natural fractures. In the oil and gas industry, two commonly used methods are open‐hole multistage fracturing (MSF) and cased‐hole perforation fracturing. Both methods can fail or underperform in deep and tight reservoirs.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.
