The author of this research mapped strata, facies, and permeability trends through a compasite valley-fill standstone in the Fall River Formation, exposed in Red Canyon, South Dakota. Findings demonstrate the complexity of depositions formed in low-accommodation basin settings.

The Leonardian Spraberry Formation is a major oil-producing formation of the Permian Basin, accounting for more than 700 million barrels of oil produced from heterogeneous submarine-fan reservoirs.
