Definition: The term shale is often used as a very general term for all kinds of clay rich sedimentary rocks. Shales are the most abundant kind of all sedimentary rocks accounting for around 60% of the stratigraphic column. As such, most of the time spent drilling oil wells is spent drilling through shales.
