View source for Smear-gouge ratio

Smear-gouge ratio is the ratio of sand to shale that has moved past some critical portion of the fault plane.<ref>Skerlec, G. M., 1996, Risking fault seal in the Gulf Coast (abs.): AAPG Annual Convention Program and Abstracts, v. 5,  
p. A131.</ref> Although not simply relatable to the shale gouge ratio, the smear gouge ratio varies in an inverse manner; i.e., high shale gouge ratio corresponds to low smear gouge ratio and vice versa.

Both ratios are commonly called SGR.
