... Testing System (MTS-810) was then employed to test the elastic properties and UCS of those partially saturated Barnett shale's samples under uniaxial conditions. Experimental results show that 1) water saturation has a significant impact on Young's modulus and UCS. Young's modulus decreases 6.1‰ with an...
