What you’ll need

A B.S. degree in Petroleum Geology
Over five (5) years of experience using interpretation software to maintain a geologic database and generate maps
Over five (5) years of experience extensively applying facies modeling, sequence stratigraphy, basin analysis, and petrophysical analysis to define petroleum-producing lithologies
