Review of Well Logs and Petrophysical Approaches for Shale Gas in Sichuan Basin, China
China has vast reserves of shale gas. Currently, shale gas is one of the focuses of the unconventional reservoir. Well logs play an import role in shale gas production, and it is the bridge connecting geology, geophysics and petroleum engineering. In the exploration stage, well logs are used to identify lithology, evaluate the parameters of mineral types and compositions, total organic carbon (...
متن کاملComparison of Three Key Marine Shale Reservoirs in the Southeastern Margin of the Sichuan Basin, SW China
This study performs a comprehensive comparison of three key marine shale reservoirs in the southeastern margin of the Sichuan Basin, and explains why commercial gas production was only achieved in the Lower Silurian Longmaxi (LSL) and Upper Ordovician Wufeng (UOW) formations, but not in the Lower Cambrian Niutitang (LCN) formation. The experimental methods included in situ gas content and gas c...
متن کاملDetermination of Time of Oil Cracking into Gas in Weiyuan Paleo-Oil Pool in Sichuan Basin, South China
Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...
متن کاملshale geological features of qiujiahe (є1q) and longmaxi (s1ln) formation
the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...
متن کاملLitter Accumulation and Nutrient Content of Roadside Plant Communities in Sichuan Basin, China
It is widely recognized that feedbacks exist between plant litter and plant community species composition, but this relationship is difficult to interpret over heterogeneous conditions typical of modified environments such as roadways. Given the need to expedite natural recovery of disturbed areas through restoration interventions, we characterized litter accumulation and nutrient content (i.e....
