By securing ownership or mineral rights to around 85% of the 1.5 million acre Permian basin, and by watching pioneering operators in the region develop more efficient shale-drilling techniques, Chevron is well positioned to try something new: earn a profit from shale.

“The market may be underestimating the ability of these companies to change or adapt,” John Dowd of Fidelity Select Energy Fund was quoted by the WSJ as saying. The firm has about $2 billion worth of holdings in energy assets.
