The Effect of Slickwater on Shale Properties and Main Influencing Factors in Hydraulic Fracturing

Geofluids, 2023
As shale gas reservoirs have low porosity and low permeability, hydraulic fracturing is a necessary means for industrial exploitation of shale gas. In this study, aiming at the problem of reservoir damage in the process of hydraulic fracturing of shale ...

Rapid and Slow Unlocking-Induced Startup Mechanisms of Locked Segment-Dominated Landslides

Geofluids, 2023
Locked segment-dominated landslides initiate when locked segments are sufficiently damaged to be unlocked. The evolution of such slopes toward instability displays either an exponentially or stepwise accelerated displacement pattern, but the underlying ...
