Study: Fracking, north-south drilling open up Wyoming oil

CHEYENNE, Wyo. (AP) — Certain approaches to hydraulic fracturing — the more of it, the better — and directional drilling appear the secret to successfully tapping a previously unprofitable oil deposit, according to a Wyoming State Geological Survey report released Monday.
