.... At every steady saturation reached, we estimated the relative permeability measurement and measured the compressional wave velocity (V p ), and two shear wave velocities (Vs and Vs*) at the 500 kHz using a multichannel pulser-receiver. We found that Vp decreased and Vs and Vs* increased slightly as brine...

The sensitivity test with variation in host rock permeability indicates that less permeable shale retards re-saturation of the buffer, such that slower increase of swelling pressure delays reduction of DRZ permeability. 1.

... interference. The pores occupied by one phase are unavailable for flow by the other (Persoff and Pruess, 1995). Relative permeability is also known to be a dynamic property because it is affected by several factors, such as stress, wettability, interfacial tension (IFT), and saturation history (Hamoud 2012...
