Hydrocarbon seep composition can play an important role in evaluating the exploration potential of a basin, play, or prospect. Petroleum in most visible oil and gas seeps (i.e., macroseeps) generally has been altered by processes such as [http://www.oiltracers.com/services/exploration-geochemistry/oil-biodegradation.aspx biodegradation], water washing, and evaporative loss of volatile components. Despite these changes, chemical and iso-topic analysis of such seeps can enable inferences about the nature of the source rock facies and maturity as well as permit correlation with known source rocks and reservoired petroleum.
