Oil shale, shale oil, shale gas and non-conventional hydrocarbons [PDF]
EPJ Web of Conferences, 2015 In recent years there has been a world “revolution” in the field of unconventional hydrocarbon reserves, which goes by the name of “shale gas”, gas contained inside clay sediments micropores. Shale gas finds particular development in the United States, which are now independent of imports and see a price reduction to less than one third of that in ...

A salt-induced viscosifying smart polymer for fracturing inter-salt shale oil reservoirs
Petroleum Science, 2019 Inter-salt shale oil reservoirs located between two salt layers are always accompanied by high temperature and high salinity. However, the present commonly used water-soluble polymers in fracturing fluids suffer from poor tolerance to high temperature ...

PINN-Based Method for Predicting Flow Field Distribution of the Tight Reservoir after Fracturing
Geofluids, 2022 The physical-informed neural network (PINN) model can greatly improve the ability to fit nonlinear data with the incorporation of prior knowledge, which endows traditional neural networks with interpretability.
