Characteristics of Tight Reservoirs in the Oligocene Huagang Formation, Xihu Sag, East China Sea Basin
… thin section observations, it was found that the reservoir rock went through moderate compaction, and reservoir porosity decreased with increasing depth. The cement of the sandstones is relatively simple, containing mainly carbonate minerals, such as calcite, ferrocalcite, dolomite and ankerite, …

New technologies for unconventional reservoir characterization: Seismic inversion, focal-time estimation, and signal processing to improve reservoir imaging
… requires a multifaceted approach to optimize reservoir development and to mitigate geohazards such as induced seismicity. Frequently, hydraulic fracture stimulation programs do not go as planned; fractures occur out of zone, depart from the predicted models, and, in some cases, induce felt …
