Woodruff Formation

Introduction
The Woodruff Formation in Nevada contains petroleum - kerogen-rich, marine deposited shales that have high concentrations of heavy metals such as vanadium, selenium, and zinc. The Woodruff Formation has shales that yield from a few gallons to as much as 15 to 30 gallons of oil per ton, however oil yields are lower on the average. The possibility of metal extraction as a byproduct of oil-shale development may make this formations attractive for development in the future. Woodruff is considered a "promising formation" for future oil development, which may require fracking.
