Fracking oil is a misleading term. The industry uses Hydraulic Fracturing on traditional fields as well as tight formation like shale. ~90% of all on shore wells today will be hydro frac’d within their production life.

interesting - have also read that there is a break point whereby if the cost would go below that point it would no longer be profitable to extract by fracking as they do in ND. Do you know what it is?
