Abstract: Hydraulic fracturing becomes a necessary method to exploit shale gas, and the imbibition behavior of fracturing fluid can cause the pore structure variation. At present, the evaluation of this variation has less been ...

Abstract: Imbibition under overburden pressure can simulate the imbibition behavior in reservoir conditions during hydraulic fracturing, about which the mechanism is still unclear. This study investigated the imbibition with overburden ...

Abstract: Bubble influence makes the measured liquid content in rock become less during continuous imbibition because it attaches to the surface of the tight sand increasing the buoyancy of rock in liquid. The imbibition experiment ...
