SK E&P America entered the U.S. shale oil market in 2014 when it acquired two oil fields in 2014, one each in Oklahoma and Texas.

Longfellow's oil assets are located in Oklahoma's Stack play, about 40 km from SK E&P America's existing Oklahoma field, the statement said.

Moelis & Co. was the exclusive financial adviser and Gibson, Dunn & Crutcher LLP and Hall Estill were legal advisers to SK for the transaction. (US$1 = 1,071.1000 won)
