... ABSTRACT: Mechanical properties of siltstone such as compressive strength and Young's modulus are commonly used in the design of geotechnical structures. This paper highlights the effect of physical properties (i.e., porosity) and environmental conditions (i.e., water content and confining...

..., and decreases with the increase of injection end to sample center distance. Silty mudstone has a certain permeability and water absorption characteristics between mudstone and argillaceous siltstone, and there is a phenomenon of fluid pressure transmission in the pores. The water absorption characteristic...

However, the fracture performance of SCDA in common reservoir rocks (sandstone, siltstone and granite) has not been investigated or compared. Therefore, a series of SCDA charged fracturing experiments were...
